What speakers do you have? This could make a big difference in recommending an amplifier.
2nd system
I recently acquired a NAD 3020 for a song, and all things considered, its a solid performer, however I could go for a little less upper bass warmth which can bloat things a bit....would a B&K st 2xxx or Adcom 535 be a substantial improvement?...I have efficient speakers and dont listen that loud...
