Vienna Accoustic Beethoven Grands and McIntosh?


I currently own adcom 5400 and adcom 600 with B&W 604s bought in 1998. I am in the process of upgrading and deciding. Of all my research and sampling, I am in love with the Vienna Accoustics Beethoven Grand, and am looking into the amp/preamp situation. I have sampled musical fidelity, krell, rotel, mcintosh. Leaning towards the mcintosh. looking at the mcintosh 6600. Unfortunately, I cannot sample the VAs with McIntosh in the store. anyone with a similar setup? Or opinions on the pairing of McIntosh 6600 with VA Beethoven Grands? thanks as always
