Krell FPB 600 or 250M's?

Buy the FPB 600/700c. I have one I bought new in 1999 and it has dusted everything that has gone up against it driving Thiel CS5i's and various Apogees, both brutal loads. The tonal weight, richness, and dynamics of this amp will keep you smiling for many years to come.

It does get VERY hot and requires a minimum of a 20 amp dedicated line (30 amp is better), so keep that in mind.

Speakers matching with the fpb isnt really a problem. From what i gather the FPB has quite a smooth upper range so shouldn't be too fatiguing with the proacs. Add a tube pre into the equation and everything should be fine i reckon. I know the proacs work best with tubes but i still like the punch and speed of SS so a tube pre should be 'enough'. Source is a KPS20i(delta 9).

I'm inclined to go with the 600 as well. From what i can gather it really is one of the all time greats and a keeper. Mono's mean more boxes, more heat, more cables, more cash if they go wrong. Just wandered if they were even remotely in the same league as the 650's which would probably be the next step up from a 600.

Just ran across this thread. I must disagree. I think the 250 monos would be a much better choice. The 600 may have more power but not even close on everything else.

I agree with Kirk930, I have owned all of the FPB series. Other than space and price ( fpb 200 vs 250) Mono blocks are the way to go! Separate power supply to each speaker and shorter cable run for less interference (are just a couple of the benefits). The best speaker cable is no speaker cable at all. So by shortening your cable run to Below 1m has neat benefits. Last but not least there is zero stereo cross talk.  
  

Strych2, I agree with you on the mono-block is better,  shorter speaker cable's,  however,  to be clear,  the 250 m is bright sounding with most high quality revealing cable's,  where the 600c or 700 is extremely better in every way with any cable's,  the only thing that would beat this out is 650m or 750mcx,  as a matter of fact,  the 700cx is better than the 650m!, the cx line is a total different animal in sound than the original or c model's of the fpb line,  I know, I have owned many, and my ride off into the sunset amplifier is the only krell modified 700cx anywhere,  I spent  $11,000.00 with up grades that will blow a stock 750mcx out of the water 😎
