Thanks for the very informative response.
The B&W N802s are transparent, and articulate all upstream (Pre-amp, amp, DVD, CD) equipment: they do run bright, based on their Tweeter (the driver, and its positioning).
My center is the B&W HTM-1: the B&W N804 in a different configuration: it's rated at 91db, as are the N802s. My concern is that DVD-A will assume five or more full-range; therefore the amps should be able to drive all speakers with equal authority and range. The 3 channel set-up is ideal, in that I'll run paired 3x for the fronts (bi-amped), run digital cable to the rear mains, run them in a 2x bi-amped mode.
My room set-up is expansive: 20x30 with cathedral ceilings: the N802s sing with my B&K monoblocks (250wpc each), but they don't have the continuous punch to drive both the normal and dynamic loads into these spaces.
A dual Meridian 558 setup would provide extra power (at extra cost) to the front LF, then a 5B-ST to drive the HFs: this would cost about $7k each for the Fronts and Rears: more than I want to spend on amplification, unless it makes 'sense'.
The Brystons have an excellent rep; as do the Aragons.
I hope this helps, and do appreciate the thoughful comments.
