The arcam stuff is nice. Expensive...but nice. If you're hung up on the arcam sound, my suggestion would be to pick up the AVP700, but skip their amp. The P1000 is nothing special and a bit expensive for what you get. You could make much better use of those funds with a more value priced amp since you'll need the extra juice to drive 3.6's.

I've got two friends with rather expensive Tact systems and both of them have remarked (independently) that if they were on a tighter budget they'd have gotten an Arcam pre and some other amp. One is driving MMG's and the other is driving Thiel 7.2's.

Cheers,
