Audio Event / Music Event
Amir,
an audio event can be anything that our ears hear. It can be live music, a baby crying, a recording, playback in the car.
Playback is much different than live music - especially if we are familiar with the recording. First of all, stereo does not have enough information to „recreate“ a live event. It can create only a plausible proxy. This proxy does not need audiophile artifacts to work.
If we are familiar with a recording, we already know what is going to happen musically. That anticipation changes the way that we listen. No surprises.
The geometry of live music is mostly not present in playback. This is because early reflections are far more prominent in domestic spaces. It is especially distorted in audiophile setups that brag about „imaging“ as a thing and not a result.
In live music, we have intermodulation. Two trumpets or a trumpet and oboe playing together create sum and difference tones that change depending on pitch interval for instance. For music in major keys, this intermodulation is additive - for music in minor keys, it is destructive. Bruckner used this to great advantage for instance. This effect is never as present in playback as in live music. This is because the intermodulation requires LF response to 1 Hz as well as integration of the highest frequencies.
Low frequency response is hugely different between audio events in a „smaller“ fixed space and „larger“ spaces. In a typical living room with the doors or inside an automobile, we have a pressure chamber. Our bodies react differently to this LF - a pressure chamber is impossible to musically integrate!
Tone: live music has „Tone“. The various octaves have a sense of pitch and softness and articulation all at the same time. Audio playback very seldom can unite these factors.
There are hundreds of further differences. You seem to want to argue, but never provide details.
I will not talk about synthesized tone from electronic or heavily DSPed music. Here there is no „reference“ tone (well except compared to the live PA sound...) and more (LF/HF/transients) is simply only more - not better or worse.

Rowuk,This is my idea about playback, and kind of a question, I would like to know your opinion as a professional musician.
I deal with this problem like I convince myself watching a movie or even a cartoon, though I know it's not real but if the package -ie. director, actors, story and etc. are convincing enough, it "fools" me to accept it as a "reality". So I may cry, laugh or feel different emotions during the event. For me same applies to my listening, the playback must be "good enough for me" to sink me in music, and when I reach to that level I become funny to watch. I act like a musician or at worse a conductorSmile

rouwk  
our discuss was about my audio judgment and my music background and my audio philosophy, you told musicians know the sound better than audiophiles and they listen to sound in musical level and you told audiophiles care about artifact sound. i think we should first close this discussion and next we could go for next discussion.please read romy post about audio vs music , i believe audio is separate subject . he can help

 This is very complicated question, rowuk, at least in my estimation. I do not argue that solutions feed our egos, there is plenty of it but it does not exhaust the whole picture. I have been in hear a strong supporter of a view that music and audio have distinctly different objectives and means, probably it is better to say not “means” but inner-mechanism for declaring itself. It is not that music and audio do not have arrays of inner-penetration, for sure they do. Still, they are different animals. It is would be similar to design treadmills and health, they for sure are connected and one can be used to evaluate other but essentially they are very different sectors of humans endeavor. 
 
Now the complex thing: the relationship between are hardware solutions for sound quality. I very much insist that quality of hardware solutions are very directly impact sound quality and very directly impact music consequences of that sound quality. I know that you expressed skepticism but I think you incorrect.  The problem is not in the supposition that I am expressing but with the definition sound quality that might be interrupted very wide. The “audiophoolery tries to convince us that there are hardware solutions [do something] for sound quality”, and they are absolutely correct. The key is their definition of “sound quality”. The sound quality that industry is patronizing for many year is a direct consequence of hardware solutions, some of them positive, some of them negative. Did you ask yourself why for over 100 year of audio industry, in one form or another, the industry never formulated more or less standard methodology for sound quality evaluation and assessment? My point is that when “sound quality” has a proper formulation in the ears (and the most important in the minds) of sound consumers then the relationship between hardware solutions for sound quality is very direct and very unambiguous. Unfortunately, the definition of “sound quality” as it been sponsored by audio industry is not the sound that has any relation to musicality or to any other human benefits … besides the “feeding our egos”. 
 
So, are the hardware solutions and sound quality related, yes they do. Does “sound quality” is a known ingredient or even to say commodity in the industry he produced the hardware solutions? Absolutely not and therefore in most of the cased the hardware solutions indeed are just to feed our egos. It might not ned to be this way…

i have told in this topic the audio is not nessesary to enjoy music and audio has his rules and it could affect us .audio to me is like buying better instrument (trumpet) to you . i ask you , do you like to have a better trumpet? most professional musicians like to have good instrument and we know they do not need better instrument because they play in their mind but sometimes they pay for better instrument.please do not say musicians do not like audio systems because they are communicate only in musical level , it is 100% wrong and i believe going for better audio is not related to being musician or not being musician. both musicians and regular listeners are equal about going to or not going to audio.
audio has his own world and it is open to you , me and others and i do not believe all musicians should be better than all professional audiophiles because musicians are every day in live stage and their mind is better than audiophiles in reacting to sound. i think this is not true and we should consider audio from a right perspective. audio is not about artifact sound and it is about reflecting beauty and power of music in our mind.the only thing we should discuss is about how a professional listener react to sound and what is the right sound. i write about it more ...

please read my first posts in this topic. i told reproduced sound is a new sound and we should not compare it to original event. all you say about stereo can not create live event is not important to me .
i do not care about mono or stereo or any other format, i do not play stereo in regular speaker position and i spend time to find a good place for my loudspeakers to hear sound from my room not my speakers.in a good speaker placement the speakers hide in room and you hear the sound from room.i will continue my response in next post.

A lot of words
Hi Amir,I have many trumpets, some for early music, some for historical playing, some for jazz, some for modern symphony playing. One thing that I teach my students is that the instrument must never be an excuse. We can play stylistically correct with many different trumpets. I choose the instruments because of their „inspiration“ inside me, for their palette of colors. This has nothing to do with an audio event.

Proper playback assumes that we understand the „Real“ geometry, that we understand articulation as it applies to voices and instruments. Only then does transient behavior make sense. It also assumes that we are familiar with Sound in space. Does the space fit the music, or is it too large or too small. Are voices plausible, not etched in space. LF and HF extension are optional when listening. Our brain can insert LF proxy information. At a live classical concert, none of the better seats has response over 15-16K and no one is bothered.
Audio recreation assumes experience, not „smarts“. Knowledge in itself is useless. The practical application towards musical goals is a very big subject. Our path gets more valid the more questions that we ask - not the more answers that we believe to have.

The catch is
people who are not exposed to a  possibilities of certain (SOTA) sound reproduction level  have NO IDEA what's actually achievable. To have a luxury of choosing five SOTA Trumpets from the masters is very nice indeed but assume that you're only able to get DDR quality tin crap trumpet made in Soviet republic and have no exposure whatsoever? Where that "inspiration' inside of you takes you ? This is reality of an average audio crowd. They are not so moronic or deaf actually.

Funny enough, the west block orchestras did not make „better“ music than the east, in spite of „better“ instruments. The reason is clear - the musician makes the music, even the „lesser“ instruments are still „good enough“ in the parameters that count. I believe that this is also true for playback. We do not need the „best“ hardware for the „best playback“. The hardware has to be „good enough“ and in the hands of someone who makes it sing.

If we start to analyse the finest playbacks, what do we learn? Higher distortion in SET? uneven polar response? Inconvenient to use? Ugly?I think not. I think that we learn that there is too much that we do not understand and that technical argumentation from audiophiles has NOTHING to do with Sound. That is the problem with this thread - more hardware than common sense.

if romy says there is information between 20hz and 30hz and he goes for sealed box bass topology because he listen to classic music but in persian classic music and some other type of music we do not need to have clear bass under 40hz .
i do not want discuss about playback limits because it exists and we can not fight it.
I agree we have many limits in sound reproduction but i think there also a large space to work in audio. i believe we have large sonic difference between those stereophile recommended carp hardware and what we hear in good hardware. listen to CEC TL0 (in a good setup) and you will be surprise how digital could sound. listen to pure power 3000+ and you can not believe how your system could sound when the Pure Power is there. those hardware directly affect the musicality and i remember when we tested good digital cable vs bad digital it was similar to listening to properly tuned instrument and non tuned instrument.  i believe many hardwares in market destroy the musicality (like that digital cable) and you can not listen to those hardware for long priode of time. somtimes the hardware it is not about good vs better , it is about bad vs good.

I have a question, did you heard living voice roon in 2014 munich high end show ?

it is true , I remember my dulcimer teacher (for 3 years i was player but i did not continue playing) told me a professional player does not need good instrument and he could play musically with/without good instrument and i believe it but we see many professional players like to have better instrument and we can not ignore it. now we back to the same question of Audio vs Music. they are separate but not 100% isolated . i had a book about beauty philosophy (Babak Ahmadi) and i remember there was an discussion about importance of body (maybe the body is not right word i do not know but i hope you undrestand what i mean) and the relation of body vs soul. it is very complex subject and i believe at higher level of perception the importance of sound is less than music. http://www.goodsoundclub.com/Forums/ShowPost.aspx?PageIndex=1&postID=50#50

Wojtek I 100% believe in you but only in right speaker placement and right room acoustics. if you listen to romy playback or those million dollars Living Voice/kondo playback (battery powered) in not optimum speaker place and bad acoustic then you will not surprise . in my idea good hardware is not more than 20% and we need proper speaker placement and proper acoustics to achieve the 100%.
I think most audiophiles never have chance to hear a good Audio playback and 99% of sounds they hear are not good.

LF extension is important
Hi Amir,we must be careful when talking about limits. We need much more than we think. This is because instruments interact. One instrument playing 440Hz (A) and another playing 465Hz (Bb) create a difference tone of 25Hz. Depending on the intensity and quality of the tone, the beats are very audible. This is also information that our brain does not substitute when playback is LF deficient. A lot of the concert hall room resonances are also LF, so our sense of space is directly affected. This is one of the reasons that a sharp lower knee is a bad thing for the ULF driver.

I have no reason to go to audio shows. The last one is certainly 20 years ago in Frankfurt near my home. I only went because a friend was exhibiting. I get to hear a fair amount of high price audio at colleagues homes. Some are interested in opinions, others only talk about their philosophy, then turn the volume up...

I'm not in disagreement with you at any level actually. I do believe though that the west bloc orchestras made better music, were more principled and disciplined and certainly on average made a better sound and better recordings. While referring to SOTA quality playback I meant evolved systems not the regular collection of high end A rated  components. At some point technicalities have to take a place otherwise it will all descend to a blank canvas with an "artists " signature in the corner and empty attempt to create philosophy justifying $100k price. It is a "GoodSoundclub " after all and there should be a place for a  hardware discussion . What motivates a guy to build a copy of Roman's system? His inner feeling or simply a herd driven desire for something better,not motivated by personal development but mostly by flowery prose of the site owner promising that the canned food recorded music really in essence is could be equally stimulating to real event. All  your ideas and actions related to playback , noble as they can be will eventually come down to bringing home another box. I absolutely believe that sensible person can have a very good system made of simple components. But without some knowledge of what's out there you're stuck with your ideas. I'm not that much interested in Amir's journey and his motivations but they are not that different than convoluted attempts of other posters. And I fully agree with Amir that people take Romy's and other articulate  "thinkers"audio solutions and apply it in the "copy & paste" manner with often comical results . Worse , against their inner feelings they will defend those solutions as the right ones. 
I didn't hear personally any "finest playback" in existence if it comes to classical repertoire. I heard a decent horn based pop&rock &jazz setups , spectacular in a sense . They also were spectacularly bad with Classical .

I think i can not undrestand your text because of my poor english.
I guess you think the listener should listen to the live music and he should judge the hardware by his knowledge about live music . am i right?

yes , hardware should be good enough but over 90% of hardware in this market are not good enough.the hardware discussion is not about "good vs best" and mostly it is about "bad vs good". bad hardware kill the musicality and very very few components are designed properly.you can check the stereophile amplifier measurement page and between 100 amplifiers you find only 3 amplifier with low feedback design and over 97% of amplifiers use high negative feedback.

Bad hardware does not kill musicality, ignorance does
Amir,there is simply too much with your posting that I disagree with. Yes, knowledge and experience with live music is a powerful tool when thinking about musical goals for playback - even when considering that they are very much different events.Musicality has NOTHING to do with hardware and everything to do with the performance. A musical message can be adequately conveyed with a Bose wave radio or cheap car system. Musicality is not a feature of a sound system in my world. It is the soul of the performer.
If we are talking about proper playback, I think we need terms that more closely describe what is happening. The audiophool speak is useless when defining goals. Distortion of geometry (placement of acoustic events), distortion of space (the physical size of the instruments and the distance between them), distortion of articulation (the characteristics that make instruments speak - related to transient behaviour and color). Distortion of pitch (when notes are in tune but sound like they are not) is a very big issue for me. Many audiophile systems have a sense of being high on the pitch. Strings need air, trumpets „brassiness“. Voices need „substance“. Proper playback can be soft and aggressive at the same time. An orchestra can create a billowy cloud and have sparks fly from the wind section. All of the factors mentioned are needed to avoid these unmusical distortions.
I do not think that feedback is a problem or that eliminating feedback is a general solution. I use single ended pentodes (connected as pentodes) with Schade type feedback for my amplifiers (RH 307A Super and multiple RH 84). The issue is how the amplifier and speaker work together.  My experiments with pure feedbackless SET amplifiers was not as gratifying (in respect to the distortions mentioned above).

How We Get From Here to There
So many "parts" to a particular hi-fi system, and not just the gear, and so many reasons why a given system turns out the way it does. Didn't Amir say he doesn't listen to a lot of classical music? I was pretty happy with tubes for quite a while, including SETs, when I listened mostly to jazz and I accepted that I couldn't get my system to convey much of the classical catalog. Once I started to develop the Lamm ML2s, however, things changed for me. I got into recorded classic music in a big way and I never backtracked. Again, the Lamm ML2s are SETs that also use global feedback, and I wonder if there are better "full range" SET amps available for a good deal of classical fare. If there is a "problem" with SETs as a genre it's that they want/need easy loads, and this is the reason for DSET with horns, to make it as easy on each output leg as possible. But IMO there are "alternatives". Regardless of what others say, I know from experience that there are better ways to drive big, conventional type drivers than typical SET, especially no-feedback SET, and especially if one wants to explore "big" classical works. On the other hand, if one listens mostly to "easy" music, then no need to go crazy trying for the "ultimate system" in the first place, unless it's the sound itself one listens to, rather than the music, and in that case one might even be happiest simply playing around with different gear as an end in itself.  In that case, more power to you, but you are wasting your time on this forum.

By the way, Robin, when I referred to "Furtwangler's incomparable war time Beethoven 7" in my Neumann mic post a while back I of course meant his 9th. You mention how great performances "trump" the gear, or even the recording itself, and here's an excellent case in point. So very true, and what a shame so many people miss so much while listening to the sound itself and/or the gear. C'est la Guerre. There have been several posts over the years opining in various ways that a well chosen table radio is better for listening to Music than a "pretentious" hi-fi system. Generally speaking, I agree.

There have been several posts over the years opining in various ways that a well chosen table radio is better for listening to Music than a "pretentious" hi-fi system. Generally speaking, I agree.

Perhaps we could create a postulate that with increasing system complexity, it gets harder to get good sound - not easier.
Actually, Furtwänglers Beethoven 7 from 1943 is VERY, VERY good. Some reviewer said something like “Two sayings come to mind when one thinks of the Beethoven Seventh: Wagner described it as the 'Apotheosis of the Dance' whereas Weber declared that his fellow composer was nuthouse-bound on the evidence of the first movement.”. This is what I hear in that 7th.

Amir,
In live music, we have intermodulation. Two trumpets or a trumpet and oboe playing together create sum and difference tones that change depending on pitch interval for instance. For music in major keys, this intermodulation is additive - for music in minor keys, it is destructive. Bruckner used this to great advantage for instance. This effect is never as present in playback as in live music. This is because the intermodulation requires LF response to 1 Hz as well as integration of the highest frequencies.
Low frequency response is hugely different between audio events in a „smaller“ fixed space and „larger“ spaces. In a typical living room with the doors or inside an automobile, we have a pressure chamber. Our bodies react differently to this LF - a pressure chamber is impossible to musically integrate!

Musicality has NOTHING to do with hardware and everything to do with the performance. A musical message can be adequately conveyed with a Bose wave radio or cheap car system. Musicality is not a feature of a sound system in my world. It is the soul of the performer.
If we are talking about proper playback, I think we need terms that more closely describe what is happening. The audiophool speak is useless when defining goals. Distortion of geometry (placement of acoustic events), distortion of space (the physical size of the instruments and the distance between them), distortion of articulation (the characteristics that make instruments speak - related to transient behaviour and color). Distortion of pitch (when notes are in tune but sound like they are not) is a very big issue for me. Many audiophile systems have a sense of being high on the pitch. Strings need air, trumpets „brassiness“. Voices need „substance“. Proper playback can be soft and aggressive at the same time. An orchestra can create a billowy cloud and have sparks fly from the wind section. All of the factors mentioned are needed to avoid these unmusical distortions.
I do not think that feedback is a problem or that eliminating feedback is a general solution. I use single ended pentodes (connected as pentodes) with Schade type feedback for my amplifiers (RH 307A Super and multiple RH 84). The issue is how the amplifier and speaker work together.  My experiments with pure feedbackless SET amplifiers was not as gratifying (in respect to the distortions mentioned above).

for defining proper playback I will write about my idea about good sound with writing about harmonic dynamic and .... be sure you will not be upset if you come to iran and listen to my system.
just let me share my first audio system experience.i really believe bad audio systems make listener sad. i had NAD cdplayer NAD amplifier and 86db Dynaudio speaker. my cell phone Siemens SL45 had a better sound than my audio system and i listened more to Siemens mp3 player. i think the audio industry destroyed audio.
this is your post about your amplifier 5 years ago :

I ran across this site quite a while ago http://rh-amps.blogspot.de and decided to have a go at building one of Alexs amps. The idea of using a real pentode the way it was originally designed for appealed to me. 
I had a chance to get some 307A tubes at a decent price and built the 307A Super. http://rh-amps.blogspot.de/2013_09_01_archive.html
It is safe to say that I am VERY happy. I am listening to more complete works and almost never zap anymore. The amp has plenty of power and that something special that makes you sit down and listen. The sense of "melody" is very good even at the lower range of the contrabass. Since the amplifiers are done, I have identified some other areas in my playback that need attention.
More on the process that brought me to this decision and what it now "after the fact" has fulfilled in upcoming posts.

I have tried the 307A in triode connection in the "standard" no feedback moron 12Axx (in my case 12 AT7) easy configuration with a coupling capacitor and it was "nice". Critical listening was almost impossible, I kept zapping around to find more "impressive" cuts. With Alex Kitics RH concept I have more than enough power (+7Watts?), and very interesting "Sound". Good recordings have a certain "explosiveness" without the etched imaging or mush of the "easy triode". There seems to be some "intelligence" depending on how "thick" the instrumentalist plays. The most important aspect is that I am motivated to keep listening and discovering things not through more "detail", rather by being able to follow the musicians line.
The zeners seem to be one of the key factors to the Sound. I tried a resistor, but the entire presentation changed in the direction of "soft". I can compare this to different trumpets that I own. The RH amp has more core and meat, the triode was big and fluffy but was more like a 3d animation than the space that I have when I am on stage. I just turn on the amp. wait about 5 minutes and listen.
In the past years I have had EL34 and 84s in various configs, a PP config the longest with relatively inefficient speakers. I changed to a 4 way system with horns a couple of years ago and there was a fairly long list of things that I thought could be better that I thought were related to the amplifier - This is the first major step.
Alex Kitic is a very vociferous designer, very convinced about what he is doing - He is very responsive to questions by mail and this venture to get a reference "melody range" for myself has been very good in terms of the sonic results and in getting some independent background behind what I am doing.
It is worth looking through his website. I find plenty of inspiration and because he sells nothing and "gives away" his ideas, there is a credibility that is hard to find anywhere else - except here.......

Exactly! And you are floating in that sheer volume of music. Like a hovercraft lifted in air by air pressure.

Amir, 

yes it is very much true but not in the context you think it is true. The main force of audio industry distraction of audio was not introduction of bad equipment or faulty audio producing techniques but seeding in the audio consumer faulty expectation regarding the entire meaning of “better” audio. As the resole we have generation or audio consumers who are kind of clueless what they do in audio and the industry juts keep furnishing irrelevant products and means of audio production to these aimless people. Frankly speaking most of you thinking about audio that you expressed at this site is just an evidence of audio aimlessness, and to a degree I feel that you are very much a victim of the consumerism of the audio industry that you are trying to criticize.  I’m might be getting you wrong, I admit that I do not read your posts attentively  but from the few that I did read I feel your criticism about audio industry is no different than a blind person criticize people who use canes or waking dogs.  
 
If you care about my view than I would recommend you to take time out of internet audio and exchanging your idea with others about audio. This is very much dead end. Focus of specific segment of music you are interested. It might be a period, a composer of even one specific work. Then learns whatever you might about this work, about the history and circumstances, get 100s different recommended interpretations of the work. Learn the world to the point that you can play it in your head. Think about this work, connect it to everything you know about life and your other experiences. Then, only then begin to listen this selected work on you playback and try to answers to yourself a question if your playback is something that helps you or prevents you to get the deeper meaning of the work or a specific interpretations of the work. If you feel that your playback does not advance you in getting this sepsis work and do not offer to you any new opportunities in your ethical or spirituals development then trash your playbacks and start collecting stamp. If you feel that your playback does something to you but not in the direction where you feel you would like to go culturally of musical then start to work on your playback. Then, only then you can ask others what/how to do with your playback but I promise you then you will be asking very different questions…  
 
Until then I do not think whatever you write manes any sense, at least to me. I have plenty of 3 years old in my life to hear their conclusions about world and I do not need to read about the same conclusions from my audio site that reportedly should be about “advanced audio and evolved music reproduction techniques”

I am done posting in or reading this thread
Amir, you are not listening or trying to understand. You are doing the same things that Stereophile/Audiogon/TAS audiophiles are doing - posting about things that you are not even trying to understand - and copy pasting other peoples ideas without understanding what they mean. I thought that I would just play the game for a while - unfortunately you are just as weak now as with your first post in this thread.

Romy had no answer - but he does have a different view that he can very well define. If you read the whole thread and understand what we are saying, you will realize that both sides are reality viewed from a different point of view.

Amir, why do you refer to someone that you do not understand (the pianist)? Why do refer to Romy that you also do not understand the context of his posting? Your pianist friend may just get great performance of the Weiss DAC and his .000000001 distortion amplifier. If you could understand his viewpoint, he may be closer to the "musical" truth in spite of your condescending opinion of his hardware. As you do not understand what he is talking about, your words have no meaning to me.

Actually, I feel that it would be best if you just stopped posting for a while and spent some time thinking about everything that has been written.

It is not the job to fix me in the chair. I can be off axis and have a great listen too - albeit with a different "Sound". Sometimes I like listening from another room with the stereo turned up. Romy has written also about this.

By the way, I read the forum posts but Romys site feature of posting Music News is very unique and attracts my attention very seriously.

I regard your audio ideas and i find them very useful to me though i do not listen to classic music. I think your audio ideas or any right audio idea is not limited to just one music type. i mean if you use purepower 3000+ for classic music then we will not get bad result from purepower on other type of music like persian classic music.
it means if there is a right direction (or right hardware) in audio then the music type is not matter. before posting here i had many times (from 2002) to think and listen to different audio hardwares and if I write here because i find some common grounds between your audio result and my audio finding.
if you think i should listen more and do not exchange my ideas in internet then i will stop posting here because i regard your view but i am sure you can not be sure about your judgment (your judgment about my audio thinking) before listening to my audio system.
I believe no body could have a good sound with blind eyes or limited experience.
If you had any interest to have a trip to iran then i will be happy to be your host. Thank you
