Vinnie I build amps where I can change components with nut removal. I use solid pure silver wire with copper and brass hardware.

That being said I have built 2,3 and 4 stage amps with all the so called great load devices. Throw in different transformers and driver and output tube variations and you are well into the hundreds to thousands of variations. Did I mention caps, resistors, wire, fixed, tube fixed, cathode, diode, and various battery bias. Did I forget to mention power supplies? Choke loaded cap loaded small cap loaded with values all over the place.

To give you an example my latest phono stage is 3 stages lcr transformer coupled go against the mainstream monster. I tried about 15 different tubes in the first position with different b+ and current. Guess what did not need a switch to tell me the difference between them. Off the top of my head and it has been a year, some popular ones 12at7 lean
6922 to rich 5842 boring Da3 transistor sounding. Of the well known tubes the 12at7 showed some real promise. The texture and tone on the piano was really good. Attack and decay where also good. It could get a little bright on some recordings so it is gone. The moral of the story no one has my phono stage not even close, so I had to try all this stuff that all the graphs in the world will not do it for me. In regards to not being able to hear differences for more than a few seconds I have no real answer.

Well you seem intent on your position. But you will not be able to further it with my lack of building experience. You could say I am delusional and need to be blind tested into submission but lack of experience, probably not your best defense.

It is a hobby that should be enjoyed so I will leave you to your conclusions. The one thing we know for sure is enjoyment is subjective. So put on John Lee Hooker or BB and party on.

Enjoy the building
