Ok, some of you suggested Magnepan 1.6QR

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.

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..

Nachtmusik, I had used all of the above amps & integrateds with different source components and wires..for the most part., So this memory rating is far from a "blind A/B" test. Anyway, the ARC 100.2, Vac Avatar..and Cap-100...might fall in that order. I believe the CAP-100 rates a bit higher than it might in some systems, because it was being used with a CDP-1 and Wireworld Gold Eclipse III wire...and those likely had big impact on that system being a sweet as it was. I think the Magnum MD-208 might be as good with the Maggies...but I have used it with lesser wires..and cd players...
