I puchased a pair and yes they are very non ss sounding,I have them running a pair of chorus 2's and the sound is very warm and detail but not in you're face,I also have a mf kw500 and a primaluna dialouge 2...these amps have a sound of there own which is very nice, now to find a nice pre amp to go with them,anyone looking for a tube like amp should give these a listen,especially for the price....,,cheers
