This is the most "tubelike" ss amp I've had in my system to date. I use it with, among others, Merlin VSMs which are both very transparent to the upstream chain and very "happy" with tube power. Prior to buying the TADs, I (like most Merlin owners) used strictly tube amps with the VSMs. Not anymore. While the TAD doesn't sound precisely the same as any of the tube amps I've used with these speakers, it "feels" awfully close and sounds awfully good. The bass response is audibly tighter than it's been before and any deterioration elsewhere in the full range has been too subtle for me to react to. For anyone seeking a "tubelike" ss amp, this is the way I'd point them.
