Best SPKR'S and cables for Krell Amps?

Dynaudios are a great match for the Krells, and FPB250 monos would give you the choice over Dyn's full range of offerings. I have the Contour 3.0's driven by the FPB200c, which is a very nice combination. The 3.0's would probably be the bottom end for consideration, though it wouldn't be overkill to mate your amps with a pair of these. Something from the old or new Confidence offerings would be wonderful as well, though considerably more expensive. If you like monitors, a pair of Confidence 3's would sound awesome. -Kirk

B&W -- The bigger, the better.

B&W used Krell amps to voice their speakers. And, since 80% of classical music is mastered on B&W speakers, you are most likely to get closest to the life performance.

P.S. I am biased. I own both.

I can recommend the use of B&W Matrix 801 series 3 speakers
(especially with external Northcreek crossovers) driven by
Krell's KCT preamp and FPB600c amplifier using CAST cables.
I have not experienced a better sounding system in my listening room...ever!

I am using a Legacy Focus Speakers along with Whale Elite Power Cords on a dedicated 30 Amp line and Balanced Granite Audio #470 interconnects. I will soon be trying Audio Pure note

I have the Krell 650M amp and I use PS Audio Xstrem Speaker cable to connect to my Wilson Audio X-1 speakers. The sound is outstanding!!!!!!!!! I've used Audioquest Everest and Transparent XL cables. PS Audio Xstream puts them both to shame with a faction of the price. But don't take my word--audition a pair and make your own decision.
