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.
