SY, I understand and have experienced that selection process. I don't intend to take up any more time and space on this thread as my points are so simplistic that even I am aware of the overstatement produced by my several posts.

I will read those items I have not gotten to as yet, but I have said enough and learned much.

Thanks for sharing your knowledge and PEACE

Should be interesting to hear from a fellow Linear Audio contributor.

"The case for subjective Listening Tests
Hans van Maanen

In his Guest Editorial, Hans van Maanen argues that although in theory decisions for audio development should be based on scientifically conducted controlled listening tests, there are many reasons why this in practice almost never happens.. Well-controlled tests are very difficult to organize and execute and the results are often ambiguous. On the other hand, there is a large body of subjective listening results and other circumstantial evidence for audible effects in audio equipment. Although not strictly ‘scientific’, when analyzed rigorously, this evidence can be used to determine promising avenues of development

you can't get any energy from a capacitor if you insist on holding the voltage at 55V.

The energy gets released by allowing the voltage to deplete.

read Gootee's Threads & posts.

i see many people using 3300uf as standard value per ampere of current drawn from the trafo. Considering that if 20amps is drawn then we need 60000uf of psu cap.

How do you calculate 20 amps?
