I have an SLI50 integrated and it is dead quiet first of all. Sound emanates from a black silence that is crystal clear and it possesses excellent dynamics both micro and macro. You hear all the detail with no harshness or spot-lighting. It has excellent extension on the top end and a solid bass. It does have a tube sound in that leading edges of notes are slightly rounded off. I will never sell this amp. It is a lifetime keeper for me. This unit is five years old and I have replaced the output tubes only and just replaced the power switch which failed (autopsy revealed burnt contacts) which is not an easy job plus a new selector switch (it was getting noisy). The parts and build quality appear excellent except the switches I replaced. They were inexpensive (8.75) and looked that way. However, they do have a nice feel when in use. I would purchase another Cary product if the right piece came along. I do use a competing brand (VAC) in my big system because they fit my requirements in that system. The VAC gear is more expensive. My SLI50 is the best value.
