In regards to the CAT amps, I have heard the JL2 (stereo) amp on the VSM and just spent four days at CES listening to the JL3 (triode monoblocks) on the VSM.... either amp has impressive dynamic abilities.
I've only heard the Tenor amps on several other speakers at shows... they are certianly nice sounding amps but I am unsure of how good they are in the quality of low bass reproduction and dynamics. I'll say that in the systems I have heard them in, they did not impress me in these areas.
I know a merlin owner who has the big Atmasphere MA-1 or MA-2 (can't recall which) monoblock amps that speaks highly of the big atmasphere's abilities in these areas on his VSM-Ms (and this gent has tried a number of solid state and tube amps), so I think these amps are also worth consideration.
BTW, just to fully disclose my own self interests, I am a Joule Electra dealer and a consultant for Merlin. I am not a retailer/dealer for any of the other products mentioned here.
