OK, now I recognize my S2 driver, thank God.
I was give to my new PS for MF channel one more change today to show itself off. I relayed the Hartmann ‘s first movement of the Shostakovich First Violin Concerto. As I said above the progress was very nice and the majority of the problems that I was experiencing at beginning were not there or were at much-much less degree presented. Still, there was an effect that I did not like, and since the bigger problem got burned out this “effect” become to annoy me quite annoyingly. I am talking about some strange micro-details and micro-dynamics eliminating noise. Those who use S2 driver properly knows that this driver has an ability to track all engravings of musical texture with a level of discrimination that no other compression driver can approach. So, my MF does not do “tracking” but rather sliding across the texture of event, filing the dynamic indentations with some kind of generic noise. Furthermore, when a tonal event decays into ambiance or is cared juts above ambiance then the event do not decay into “ambianic nothingness” but rather it dives into a “foggy noise-like substance”. Do you know what happen next? What the tonal event ended then the “foggy noise-like substance” is ended.
I really did not know what it is. Bad electricity gives it but left channel have no such an effect. So, I decided to take actions. I got rid the last 100uF Ansar polypropylene cap in MF power supply and replaced it with my well tested and well beloved 250V/3000uF Nichicon electrolytic and just “in case” bypassed it with 100V/1uF MultiCap RTX.
When I turned the amp back (again the MF and upper bass only) it was with the very first none obvious that ALL problems are gone. You remember the bass section opening of the Shostakovich First Violin Concerto? Before, playing it juts with MF it was not sound from channel but a spray of radioactive noise. Now it was… nothing “radioactive”. With the very first second of the play I know that the problem was not there anymore. The rest of listing was nothing new to me and I did not detect any issues of any kind that would make me to be concerned. So the journey with power supply for one-stage amps is over. One more notch on the project. Now I might covert the left amp to dedicated PS for one-stage amps and the entire project of 6-ways Super Melquiades will be over
Does the new dedicated PS for MF one-stage amps sounds better than in the situation when I sors3ed voltage from B+ of 6C33C? I do not know. Perhaps before I convert the left amp I would need to make this observation for myself… Perhaps I should… anyhow, now I am happy. Well, happier…The Cat
