The Levinson amps are very neutral and impose no serious coloration upon the signal going through them. IMHO your problem may be with your front end, or maybe your speakers.
Best amp to use with ML Aeon i speakers ...
I am using a Levinson No 331, purchased earlier this year, with my Aeon i speakers. The sound is very, very transparent; by this I mean; cystalline highs, clear mid-range, and bass that is not at all booming. The problem is this; the sound seems somewhat on the sterile side, very analyitical, and not terribly realistic. I am not looking for a "sugar-coated" warmth in the sound, but would like to hear from anyone who is familiar with these speakers and amps. Any suggestions would be appreciated. The rest of my system; ML No 380 pre-amp, Meridian 588 CD player, VPI HW 19 Mk III, and Audioquest / Harmonic Tech cables. I listen to classical - small and large scale - and opera almost exclusively.
