I have matched this monster to two different Krell pre-amps and most recently to Audible Illusions Modulus. The Krells were tight, clean, awesome in their soundstanging. But high-end would roll off. The AI, on the otherhand, doesn't control bass as well, but the lush tube sound is very sweet. Depends on your music tastes, I guess. I originally had the Moscode 600 (with mods) being fed by the Melos GK-1 preamp. Wide open and gorgeous sound. Try it all!
