Right now, I pretty much like everything but two things stand out. First, I have never heard amps sound as good in my system as the big Class A Clayton amps and I have tried out more than a few highly-regarded competitors. They simply sound more real to me than others I have tried. The closest competitor was the Lamm M1.2 Reference amps that I also could have lived with - but I like the Clayton's better.
Second, my recent move to large (105 lbs) monitor-type acoustic suspension (i.e., sealed box), limited low frequency (i.e., 40 Hz) speakers on stands along with two high quality subs has improved imaging and has greatly improved the mid-bass response, bass depth, and impact, even at low volumes.
Good thread @elizabeth
