I agree with most of the above posts. The difference really rears its head when distortion occurs. I just prefer the sound of tube distortion. I would rather have 1% of tube distortion (or whatever my Jolida JD102B is) than .001% of solid state (or whatever my Krell KAV300i is). This shouldn't matter if your equipment is adequate for the job, but I would still go tube, myself. The only solid state amp that I have found even remotely tolerable is the Musical Fidelity A3CR.
