The B&W 801 Matrix Series 2 and Series 3 speakers are incredibly neutral. If you can deal with the size/appearance, and if you can get them to proper height (look for the stands when you buy), I highly recommend the speakers.
I had a pair of 801 S2, which finally failed on WAF. I cannot say that I've had anything that was heads and shoulders better sonically, and the things that edged it out (Salk, Nautilus 801, etc) were far more expensive than these gems can be had currently.
Do check the state they are in though. They are old enough that the tweeter (esp in S3) can have dried up, there can be surround problems, and the crossover caps may be ready to be replaced.
*Also: though not nearly as demanding as the N801 that replaced it, I still would recommend putting some decent current under the 801 Matrix for best results. I used a Yamaha P4500S, which worked really well. I do not recommend running them off an AVR.
