@devinplombier Thanks for the boost of morale.
@kennyc If we all had sufficient hearing, there wouldn't be such a debate to begin with. Some of you might be familiar with Erin (Erin Audio Corner). He "reviews" a lot of stuffs. Measures a whole bunch of stuffs too. A respected member of ASR and AVS. He had openly admitted in his Youtube videos that he cannot tell the difference from one amp to another. One time he compared a tube vs a SS amplifier and the two sounded identical to him except for a bump in the bass on the tube amp.
Here's the crazy part. Most amps I've heard sounded different when freshly turned on vs being on for 90 mins. The same amp sounds different depending on warm-up time. Let that sink in....
