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.....

[quote user="Paul S"]It seems like many speakers that might be acceptabe at low to mid volume with simple music begin to compress and otherwise screw up when "pushed", either dynamically or with more complex music. Of course, plenty of people really ...

[quote user="miab"]I'm about to place an order for some 12AX7 tubes. The GA 12ax7 tube you mention doesn't seem to come up in my search. Is there other info regarding this tube?[/quote]I am not sure but it is possible that General Electric never ...

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 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...

The preamp has the classic tube regulated power supply using 5R4, 6AS7, 6SJ7. It is transformer coupled output and has no capacitor in the signal chain, the gain is about 8db, so it is not a buffer. For convenience, it does has a remote control. It i...

Edgar, of course I am not interested in blanket "recommendations" out of context. After all, it's a Big World out there, and time grows short for me. Do you know that there are several GSC threads where RI has been discusssed, going back some time? S...

I see now. Quad can’t be driven by single 6C33C. This is well know fact and I did a lot of experiments with Quads and Lamm ML-2.0. For whatever reason as ML-2.0 drives Quads it produces Stingy Sound. I can’t explain it but it is not the sound that ML...

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...

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 ...

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...

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...

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,...

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; ...

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="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...

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...

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="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...

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...

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...
