I can hear differences when I switch out OPT transformers and that's without a switch.
Are you using the same manufacture and similar specs on OPT's?
I always felt like the OPT was 75% of the sound quality as long as you got the circuit in front of it within the tubes ideal operating curve.

That's the part that is really interesting, the opts are quite different. I do not understand what is happening right now, but I would really like to hear from someone who has tried the same experiment. So far no one has replied that has.
I have only done this with speaker cables swap.
Did you try this with higher sound levels using dynamic music content?
I was just going to add a post about this! One thing that might be causing it is the fact that I am using music that is not very dynamic and playing it at only moderate listening levels. However it is the music I mostly listen to (jazz, blues, soft rock) and the level I listen at, so it seemed appropriate. This would tend to suggest that the differences in amps might not matter too much under average listening conditions unless you are heavy into dynamic music. I think using more dynamic music at higher levels might be problematic for testing this way due to room acoustics and the shortness of the passages. I will give it a try in the next few days and see what happens.
Also, I wish I owned a SS amp that I could try against the tube amps. If I could not hear a difference then I would be really surprised. Might have to look for a used one just for the knowledge.
