This is difficult because the sound of your system is effected by everything in your system. Now that that is out of the way and given the above, I like the D’Agostino upper end models. I really like the sound of my First Watt SIT-3. So clean and uncolored.

Just got to hear a couple classic Threshold amps, I totally agree!  Great sound paired with a nice tube pre and quality source.
I like my YBA 2 amp with Vandersteen 2 speakers. Is it the best I'm sure it isn't but it gives me enough to stop looking.
