no, not really... the general concensus around here is thst most solid state amps "sound" the same. i personally have never heard a tube amp, so i can not speak to that... i have solid state amps at 3 different price points, ranging from the 1,000$ area to the many many thousands of $$ area. to me, they all "sound" the same.. the big difference is the amount of power.
one thing you may notice is, me and john are discussing more the power and calculation there of, with no mention to the "sound". This is primairly because me and him both agree, and know we both agree on this point
That's my take anyhow....
