Romy, et al, I got rid of my tube tester a few decades ago... yet I still need to match sets of tubes for equipment. When you consider many SE designs with no feedback loops, you need to match "sets" of tubes to get matched performance between ampli...

And as one of the other perpetrators...The nature of this kind of thing is compromise. The owner of the bass horn system wanted to run them together, for the enlarged horn mouth, and so we did - there was never going to be enough time to play about ...

The Japanese Christopher Witmer posted at the Sewers some finny pictures of another Klangfilm “invention”. It is hardly could be imagined more bogus design for a two way horn systems – no wonder that people hate horns…
I wonder if one of the ...

Well, I figures that while I am not sure what to do with LF section and where to locate it I will live with my woofer tower from my old listening room. They did not work well as Lower-Upper-bass channel installed next to Macondo but in odd place, han...

Work has been so crazy busy all last year and through these strange times right now that I have not been having any time to think about the audio project let alone indulge in advancing it. One DSET/Macondo has been playing mono and I have really bee...

If it is the CG it should say Dia 25 somewhere - unless it is for 78s when it would say Dia 65.
"Dia" for Diamond, the number for the diameter in microns.
I guess if it doesn't say this it will be the SPU Mono.
Actually, if you remove it from th...

So what was next...They build the DAC, patented the clock... ok.They build their own preamp. Fully descrete class-a balanced, john curl wouldnt do it differently. Nice. Low and adjustable gain - very nice. Constant impedance step attenuator - my favo...

[quote user="op.9"]Yes, I agree they are different issues. However, quite a big however too...It all depends on where we believe 'reproduction' starts. We are very rarely simply reproducing the feed form one single microphone. Choices are made very e...

...simpler...Yes, I heard 90x multiple times in the diverse systems but it was never possible to make any judgment about 90x as the systems always were inadequate. I got feelings what 90x’s sound is all about. Mostly got the feelings from the feedbac...

I keep receiving emails asking me and complimenting me about this “Chernobyl Arm”. I have difficulties to estimate the worth of the entire project and the most important to pass the value of this worth to others. The project was very valuable f...

[quote user="cv"] But the real reason for my post is to ask:I was thinking about the results you reported and am really scratching my head as to why the FC S2 should sound honky, given that its acoustic geometry is completely unchanged. Any idea...

When you say it was not very high end...but that you found the sound very good....doesn't that mean you should redefine the term high end?
Also. Why can't the purchase of a $20k speaker in itself not be regarded as audio ambition?
Regards.

Best amplifier is the one that you just built…Yes, it is a common unfortunate law of Audio but the people who know me personally know that try do not behave according to this behavioral pattern. So, this weekend I decided to do try the new Melquiades...

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="Romy the Cat"] When you used your 25Dia then can you recall a similar experience at the beginning of the cartridge live (sharpness and bass)? [/quote]
I have yet to own a CG25 Romy, my very first Ortofon - SPU Mono - is on its way fro...

First off, I will point out that neither Silbatone nor I claim or agree that the Aporia horn is a point source, because clearly it is not. The sound comes from two "areas" but even that is not a particularly useful notion.Although some do make that c...

Finally, it has happened. Sound. Two weeks ago I had a couple of mates help me carry up and install the first DSET on its pedestal on the horn stack. It was quite a bit of effort and three were definitely required for the heavy but delicate operat...

[quote user="jessie.dazzle"]To my understanding, taken individually, your attic horns would be more obviously working in a half-space environment. For any output that is common to both the L and R channels (some in the case of stereo recordings a...

I have 4 arms on my TT: reference stereo, romantic stereo, mono and the “shitty” arm. The “shitty” arm is Grado Reference platinum needle with SME M2-12 arm. It is not shitty arm but it has shitty purpose in my setup. When I buy records I pay the...

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 Vincent SP-T100 looks close
"The SP-T100 is a hybrid mono block with tubes in the input stage where voltage is amplified. The power output Amplifier circuitry works without feedback."
Nominal output power Class-A 8 Ohm: 10 Watt

I've no idea if the LP will be better. In my experience Mike Dutton really makes excellent transfers. I'd be fascinated though if you could do better...
BTW. do you listen to mono recordings with one single speaker? I've listen to this recording b...

Hi Romy
I have a mono completed full range Melquiades and another only with the bias circuit hooked-up.
The bias voltage I get on the 6e5p is around minus 4.4v on both the circuits. This is with the inputs shorted. With the inputs connected to adj...

Here is an opportunity to here in slightly better. It is 24/88K, 47M mono - file with Kalman from 1954. Do not download it is you can not play high resolution files.

Hm, this is what I am playing how: the new 18-cell and S3. I run it from a full time Milq and use it with no filter of any kid. Rony is right the depth effect is there, it is not even depth but rather multi-dimensionality. Indeed very pleasant feelin...

[quote user="jessie.dazzle"] I don’t have a pair of Melquaid DSETs. I drive the horns with a pair of Lamm ML2s, running full range. I use a second pair of M1.1s for lower bass. The ML2s are hard to fault. In fact at this point, I can only find positi...
