Romy,I try to remove the step-up transformers & short the
input grid, the hum has gone.Than, I did next changes:1. Twisted wire from input RCA to step-up transformers. Connect transformers input & output ground directly (not thought ground ...

...IMO, at least. I strongly believe the name of the publication game is entertainment and the vehicle is audio-visual hardware "news" & "opinion" & pictures.[quote user="guy sergeant"]I stopped paying any attention to the ravings of magazine...

Hi Romy Im just trying to imagine that. If you got to keep the vertical offset small, between the ways, this would rip a hole in the middle, wouldnt it ? Also bit surprising as i thought you liked the injector on the ground initially. I hope I unde...

Hi Romy,I guess I view absolute tone a bit differently than what you describe. I think that each real instrument or person (as in singer) has its own "absolute" tone. It is the sound of what it is (or its gestalt). The ideal speaker...

[quote user="guy sergeant"]The load lines are horrible. I can't imagine it gives a very accurate representation of what is fed into it. Maybe that's not what you are after.[/quote]It is not that I completely agree (or completely understand) the Eduar...

Thank you all for your ideas and suggestions on RTA.Romy -- you are correct, measurements always need to be made in context of sonic experience and more importantly musical intention. For me, though, to begin the process, I need to unlearn much of wh...

[quote user="Paul S"]Andy, I will say right away that I am not at all set up to "exploit" online music, but this comes across to me as "clean" and "noise free", with some nice spacial effects, basically devoid of harmonics, and not much in...

[quote user="jessie.dazzle"] Back when Fane were still in business, I ordered a pair in 16O (I don't know if there is a theoretical best choice between the two for horn loading... Any thoughts ? However, the 8O model will require a smaller coil in th...

[quote user="Romy the Cat"] Even if it is possible with a given (multichannel, faulty design) loudspeaker then the DPLOS become very fragile and appears/appears too sudden, without a gradual improvement while approaching the DPLOS. The keys are phase...

Yes, Paul, you are right that it has to be pointed that the frequency extension, by itself, does not guarantee anything (but that’s why I posted the thread in Audio For Dummies section :-) ). OK, now let’s see how the tweeters should be used (in cont...

Experimenting with Decca carts, I've temporaly disconected the SUT's and decided to check the RIAA calibrationand I think I have some (circuit?) problem.[quote user="Romy the Cat"]
In the end of everything I was able to get very nice response. The...

Thorsten Loesch who came up with the mods, details what caps and why on the first page of this thread. Lacking interest for multiple years of auditioning caps, I just built it that way (2012 or so) and have had no urge to change anything. Romy has pi...

I have identified a direction for my next speaker system. Whether it is a good one or not is a different topic -- I think it's a good one because I've lived with my current horn system for 10 years and have since developed an understanding of it's st...

I must say that I have always thought the Cardas "Golden Ratio" schtick was pretty lame. So it was with no small measure of trepidation that I sent off a rather outlandish sum of money for two Cardas Golden Whatever 4.7 uF caps for th...

Romy,Your Macondo system is something that has been a "role model" for what I'd like my playback system to be in the coming years. And much of what I've learned about horn playback systems I've learned from reading your writing and other posts on thi...

Hi Romy,Well, this is my (and my dad's) first horn system so we're learning/building one step at a time. Our motivation is simple, to use horns as low as possible.The very first DIY configuration was:TAD ET-703TAD 4002GOTO 505TTTAD 1603 Woo...

[quote user="DHT4ME"]Well we know that Steinberg who created Wavelab is also behind ASIO. The Ottachan ASIO notes state that Wavelab was the sonic standard for compiling the plugin. It is possible to get very close to the Wavelab sonic standard...

I read one more page from the Tenor description, before the author begun to talk about sound. A correction need to be made, from the first pages I understood that the amp use 6N6P driver but on the next pages it was not the case. Perhaps I confused s...

Romy,I know you know there is no such thing as perfection.My favorite quote is from S. Dali who warned, "never fear perfection, you won't achieve it". But in that statement are, at least, two messages.Nothing wrong in striving for perfection. Being...

Romy I have not herd so much doulble talk in a long time. Some of the best sounding drivers on the market in the last 60 years, were for sound reinforcement. I do believe, in a 2 way speaker system crossed over at 800hz with a good wood horn i wil...

I think I need to make some commentary in here as BS will be swallowed as usually and somebody shall take stand on it. Before is a small prelude. Sometimes back in his comments about RMAF 2010 Show Report the Federated Mike wrote in his blog:

I think it is quite helpful to have some information about VTA in general.In the 50's there was no cutting standard, that means, every Label did cut their records the way they wanted ( the angle for Mercury, RCA LS, Decca etc. are all different). At ...

[quote user="Ronnie"] Listening to the horns, it seems that they indeed die somewhere below 120Hz. I was surprised, and a little disappointed that it seemed so steep. Good to hear that it's to be expected!!Yes, I'm using a 30-something-Hz 1st order h...

I do not blame John Atkinson specifically. He is not better or worse than any other his idiot-colleges. Take a look the level of the moronity this time John Atkinson allows himself to fell. In his “review” of Lamm M2.1:
