Chris,

I see where you are coming form and I was thinking about it myself. I would say that anything above 0.68uF was in somewhere listenable but I would not say that it was day and nigh difference. The increase of capacitance GRADUALLY improved sound and the larger cap was there the more natural HF were. I think if I put in there 4uF or 6uF then the result will be even better although the common sense sagest threat the more turns I have in the caps then more then should be prone to the “vibrative” distortions. Yes, the 2uF was better then 0.68uF (quite substantial better) and it still dose not make sense as the difference between them 0.8Hz and 2.3Hz.

I certainly would not insist that the modulations have anything to do with it – although the look for me the most plausible explanations. BTW, I did drop the load of the filter down to 30Hz when I use smaller caps and had no effect. I mean I gained some very minor amount of HF but the nature of Sound did not change.

Running the fully closed Super Milq for a few days I noted some amassing qualities that took the HF performance of Super Melquiades even further then Melquiades. This quality consists of a complete absent of any king of glitz and very atypical for the 6C33C gentleness. Certainly a new “yellowish” driver in HF channels and using a half of the 6C33C do pay great dividends! The HF channel was a reason of some concern of mine as the HF channel has too high PS capacitance that always makes sound harder and was planning to drop the last cap significantly. Most likely I still will go into this direction but for now I am experimenting with a new output tube for HF channel. I will post my observations about this journey when I will be through…

It is kind of pleasant and insulting at the same time. Insulting because I thought I know the Super Melquiades better then anyone else or at least was able to say about the Super Milq Sound whatever might be said. :-)

However, today my ego was severally damaged. I have today a third person in my room who heard the completed Super Melquiades and when I, as usually,  was asking about the problems with my Sound, he made very fascinating comment. The comment was very interesting, educational and it made me to look at the things differently.

He said: “The Super Melquiades makes Sound that allow you to hear very clearly the lowest octaves of the bass instruments but you do not hear.... the actual bass.”

Think about it….
