Craig,
I don't think we are necessarily in a fundamental disagreement. I do NOT claim that all amps sound the same (although, at least for me, detecting a convincing sonic difference between good SS amps has been fairly difficult). I have no intention, expertise, experience, or guts to make such a sweeping generalization.
Incidentally, as you may know, I used to design and build more than a few serious tube amps from scratch, and I knew each one of those sounded noticeably different. If I had started with an a priori assumption: all-amps-sound-the-same, I would not have been interested in designing and building DYI amps in the first place.
Just that in the specific context of slack's auditioning, I have to say that NO AMP will change the bass sound character nearly in the magnitude of differences he was hearing between the M22 and M3 (unless we are talking about a tube amp with a very low damping factor). In that sense, the salesperson was still BS'ing a big time. That's all I meant.
Don't you agree?
