What amps are being used with Revel Studios?


Those of you who have already purchased Studios, what are you using for amps? I'm about to start auditions and thought I'd get a head start from the knowledge/experiences here.

I am using Harmonic Precision. Mark Levinson is the standard. I knew people with Harmonic and it is a unique product I love, but Levinson 436s are probably as good as anything.
The Proceed HPA-2 sounds wonderful with the Studios. In fact, as I understand it, the Studios were voiced with them.
I heard them at a McIntosh/Levinson dealer. The McIntosh 602 was more musical than the Lev 336 they had without giving up any detail, depth and impact. The front end and cabling was impeccable and the source material was mine so I was familiar with the selections. I was told the McIntosh tube amps also do a good job but heard them only on other speakers.
