Thanks to the field for the comments. The comments on Base Extension make a lot of sense based upon my experience with my N802s. I may, in fact, consider a pair of Rels (I use one now) if the remainder of the frequency range and sonics are good enough.
Nealvb: If you have a chance to listen to Avalon Eidelons, you will likely be impressed. To my ears, they are extraordinarily musical, with good (not great) dynamics, an excellent full range, and mind boggling sounstaging in the right room. It is relatively room and electronics critical, however. I love B&W Nautilus speakers, but have to say that they (801-805) are not in the same league as this speaker. The N800s should be interesting, though.
If the Eidelon is too pricey, try the Avalon Opus. They give you a great deal of the Eidelon, but are more equipment and room tolerant.
