I'm enjoying this account of Melquiades upbringing. I must ask though: how are you sure that what you are hearing isn't on the recording? Not that I don't believe you, I just wonder if the stuff has been there all along and undiscovered until now.

Well, I would not say that “it was not on the recording” but rather it was not retrievable by any know to me means. Those very minute fluctuations of dynamic assents are completely not handleable by any amplification that I have heard. Our amplifiers amplify everything EQUALLY. It is very much like a microphone that “hears” of the far-located sounds too prominently (our awareness filters them out). Melquiades does not amplify dynamically-linearly whatever it gets but it does it in a VERY different manner: It emphasizes the things that should be emphasize and subdue the things that should be subdued. So, when I tell that “Melquiades Sound” ™ is an absolutely unprecedented and unique event in audio consciousness then not juts my drooling about my new amplifier but my very sober recognition of the fact that “Melquiades Sound” is a quite revolutionary achievement in audio.

Then again, I understand that the driver valve does have some fairly unique distortion characteristics which in conjunction with the 6C33 are giving these results.

Chris, I can’t explain why it happens. I do not think that 6C33 in a picture in here at all. I would say that “Melquiades Sound” does not “use” the 6C33C. I think that hard of the “Melquiades Sound” derived form the “unique distortion characteristics” of the driver stage and from the unique biasing-decoupling topology of the first stage. Before the Melquiades was born in the way in which it exists now, there was multiple versions of the same basing topology tested and evaluated. All of them “operated” OK but the “Melquiades Sound” was born only after the “dual active basing” :-) was employed.

OK, you've convinced me: I'm going to build one... perhaps with an aircore toroid OPT for the S2.

In the “Super Melquiades” where the S2 will be driven by a desiccated channel I will be using an air coupling cap between the stages and OPT with reduced number of turns, low inductance of primary (~1.5H).

Incidentally, I must agree with you regarding the S2: in its range, it is wonderful, it is just simply more alive and vibrant than any other driver I've heard. What I also like is its composure; at low levels, it has a very delicate touch and when it is called upon to raise its voice, it does so without strain. Unlike other drivers which sound like a teenager whose voice has just broken...

No kidding? :-)
