I'm kind of glad I went the pre/power amp route as well.
I have a DB659/PLX3402, and finally got to test out a DB750 into an Aggy 410 and 212 at GC this weekend, and it totally blew me away.
It sounded really close to my pre/power setup, so, just lettin' ya know that you're not losing much after moving from the by-itself head unit.
However if that Aguilar endorsement ever came along, I'd be more than happy to have a road crew lug a few 750's around...
