[quote user="manisandher"]The only issue that I have with it is that I can't use the PMII in Master mode at rates of 176.4 and 192KHz... the AFI1 cannot double the clock frequency from the PMII.[/quote]The latest firmware 'fixes' this issue. The AFI1...

This is left channel. Right channel is mirror image.I am using 6db active crossovers all around.The subs are pair of 18" Aurasound 1808 per side. The current midbass is the white color horn you see. It is Funktion One DS15. The issue with this one i...

A “casual” look at full range usually results in 3 or 4 way playback for standard dynamic drivers or horns. There are a handful of “full range” commercial efforts from Edgar, Wilson, JBL, etc that are doing similar things with the range of each chann...

Some background first... My first initial foray into buying some decent speakers took me onto the path of Quad 57's, they had their limitation that are well documented i.e. sweet spot, not the most extended treble and not a speaker for a party.....

Hi Romy,
I spoke to Mr. GOTO about your question today and he told me that the reasonance of SG145LD4 is at 24Hz. If customer want to build a 20Hz, he will recommend to use at least 2 driver per channel but best to use 4 driver per c...

Chris,I wonder what your like in the Quads, the actual performance of the loudspeaker or the way in which those delay lines shape the front of the attack wave? Anyhow I thin to mention the Quad in the Vitavox S2 thread would not be ethical… :-)...
|
|
I see, this tri-way Quad system for sure shall be much different from regular Quas. I kind of even understand why you stay with open baffle bas to support the system’s bass. For sure it will not Bruckner-style pressurize a room as non-dipole bass wou...

It is interesting indeed how people allow their attention to go from fixation to fixation without ever changing/adapting methodology, believing none the less that each single idea in turn is The Answer. I remember the first time I heard th...

I think conceptually it would be great if everything were streamed even at CD levels. For 90% or more of listeners that would be an improvement. Given the wide scale manipulations in the remasterings being done by the iphone listening staff at the re...

[quote user="noviygera"]Number one, that I'd like to run by you guys due to it's simpler nature and closer to reality execution is the idea I have been thinking about. No first hand experience with any of this.Say we use something like altec 1505b mu...

Romy, hi Firstly it's probably worth a few minutes about me and my preferences, this will probably add some context. I have 'preferences' and priorities that don't match everyones, but are somewhat consistent with my group of friends who have hifi s...

Here is a VERY interesting paper http://www.anstendig.org/Stereo.htmlSTEREO: A MISUNDERSTANDINGTHE THEORY, SOUND-SYSTEMS, AND PROBLEMS OF HEARINGThere is a common misconception that the addition of stereophonic sound-reproduction was the necessary, c...

Well, maybe a little cussing first to set the tone. The older SPU's are now well sought after, many will end up in collections at now over inflated prices probably in the Far-East where they are worshipped. I've heard a few older SPU's and even those...

Thank youxandcg do you think Voyage MPD/ALSA/Ronald Config is not bit perfect? or you think it is not good?AMR (thorsten) guys in munich 2017 recommended my friend to use Volumio . Volumio use Debian/MPD/ALSA and they claim it is bit perfect.I think ...

Without regulation, this amp would not work correctly due to its design: DC coupled and fixed bias. The high transconductance will make the bias current varied as much as 50-100ma due power line fluctuation without the regulators. It mi...

I agree the "period" closing needs more words, Roman.The P.A. horns/drivers were mounted in stadiums, convention centers, maxonic halls, cinemas, theaters, everywhere was needed a broad music or speech dispersion, trouble free operation and high S.P....

Musicians do respond differently to music than non-musicians. Brain scans have shown that different parts of the brain light up when their 'genre' of music or something close to it, or otherwise something easily comprehensible, is played to them,...

Paul,
I have been working with trumpets since 1966 and horn speakers since 1975. I have built both and am pretty familiar with what they are, the similarities and the differences.If I had to pick THE major sin when thinking about all of the horns th...

[quote user="KOTriode"] On dynamic, the 6C33C tube showed its ability to go deep in the bass on Ray Brown trio recording of Soular Energy which is excellent for a 15W SE , the 845 amp can do better, but not by much, but probably because of its 25W ou...

[quote user="Gregm"]This would involve some researching... thus introduing (possibly unecessary) complexity: look for a Sony or Yamaha or Sansui "power j-fet" amp. These were produced s/where in the mid '70s and should be very cheap now. I have ...

I chose the EdgarHorns for fairly simple reasons. I have listened to them and I loved the way they sound. They are not the perfect loudspeaker, but they make much truer music than what I have now. Also, the price I paid is less than...

The other night I listened to a Girl with Guitar master tape. A friend has a home recording studio that would make most comercial studios not only jelaous, but also broke. A highly modded ATR 102 in 1/4" half track and a vintage stereo microphone; ...

I have heard hundreds and hundreds of audio systems and mine is by far the best. Honestly nothing even comes close. There is a scientific reason for this. MY system starts with a PERFECTLY tuned room...something overlooked by ma...

The reason that I built the 6C33C preamp was to explore the 6C33C true musical potential like I did with the 845. Not only did I compare the sound of these tubes in power amp, but also in preamp. The reason is that with power amp you might hit some l...

Wow! I did not realized that almost 4 months have passed since I wrote last.
Quite a few things have happened the last 4 months that I have played with the 6C33Camp/preamp combo. I have tried at least 3 different vendors on the Ulyanovsk type, the ...

[quote user="el`Ol"] I know the PAC tweeter of the WLM has the best transients and transparency of all tweeters I know and so is the best tweeter above 5kHz I know, although I hated the implementation (crossed far too low, harsh-sounding upper midran...

Can you remind me what you do at this forum? I mean, if it is what you like then the BS of a horn-snob like me that being constantly expressed at this site should relay drive you nuts… :-)
Anyhow to be a little bit more serious: my problems with Qua...

Romy,It is indeed an interesting subject; I am instinctively drawn to it due to the fact that the majority of orchestral instruments - the majority of my listening is orchestral/chamber/classical soloists - produce their own sound through the resonan...

[quote user="el`Ol"]David Wilson says about the WAMM:
Atkinson: What range does the electrostatic unit cover?
Wilson: It operates above 5kHz. And it operates at a very low level. It functions primarily to provide part of the leading edge of high-f...
