Krell FPB650m or FPB700cx


Setting up a new system for my in-law and he likes the Krell line of amps.

His pre is the Cary SLP 05, speakers are Wilson Sophia 1.

Now he wants amp that will provide him with extended highs and nice defined bass. Also wanted minimum watts of 500.

There is an opportunity to purchase either of these amps for approx $8000 and $6000 respectively.

His budget max is $8000

Any suggestions or recommendations?

thanks

I've been partial to monos and love the Krell line. I don't think you can go wrong either way. A friend has the 650s and they really push his Lat 1000's.
I used the 650Ms with my thiel 7.2s for a few years. They are very good amps, but in comparison to the 700cx i think they can sound a little dark. I preferred this, but many people dont. Both very good amps, win/win choice.
"Also wanted minimum watts of 500."

The Sophia is a fairly efficient speaker. There is no logical reason to need 500 WPC on these speakers
