Ok, some of you suggested Magnepan 1.6QR

I don't want to suggest that the 1.6's sounded bad with the dna. In fact it was quite excellent. It IS a good match! I just noticed that you could hear the tube 'liveness' and the solid state 'deadness' much more so through the 1.6's. I've never heard a speaker for which this was more apparent. The coherence provided by the panel driver was augmented by a tube amplifier's spaciousness. Amps shine with different speakers. The dna was head and shoulders the better than my vt100 with my old Vandersteen 3aSignatures, and neck and neck on my AP virgo's. Individual tastes will vary.

I have used the 1.6 with the VAC 30/30, Classe CAP-100, Classe CA300, Sim Moon I-5, VAC integrated, Magnum MD-208 and the Audio Research 100.2.....and the speaker is just superb with them all.

TRY A SPECTRAL AMP IT IS LIKE A RACE CAR AND HAS ALOT OF CURRENT WILL HAVE THE MAGGIES DANCING OFF THE FLOOR.

What is your preference amongst the listed amps, if you have to pick only one?

Nachtmusik, I will try to answer your question...I need to think a bit first....so much of each system is based on a combination of components and cables..
