Opinions On Used Speakers music only $5K $6K


I'm looking for opinions on a pre-owned/demo Speaker purchase between $5K>$6K for an all-Krell-music-only- system installed in a 26'Lx20'Wx10'H sitting room with good acoustics. I've used N804 & N803 with good results (detail/imaging) but feel that I need larger Speakers to realistically fill this room. I have auditioning access to Krell, Revel, Wilson, B&W, Focal & Sonus Faber. My first reaction is to try to purchase a used pair of N802 or 803D. Any other suggestions would be greatly appreciated.

I'd suggest the Daedalus DA-1's. They will love the high current delivered by your Krell and make beautiful music. Check out my review posted here on the A'gon as well as comments by many devoted fans. Do a search under Daedalus.
My first thought is a pair Avalon Radian (maybe HC or if you are lucky a pair of Ascent).
Size of the room is a problem for really filling with bass, agree with Nick. However, IRT the N802 and D803, there is no comparison. Buy the D803. It is better in every way then the older N802. Buy a new pair if you have to and have the dealer hook you up with a sub. If you like the B&W sound of course.
