Mono blocks vs 2ch stereo single amp / Krell

I have a gas fireplace in the center so I can't set it up with the amp in the center. I need to remove the fireplace or go to mono amps. A different location will not work in the house. I could raise the fireplace and locate the amp under it, but I really don't like that idea very much.
Thanks, John

Go with the monoblocks. I had compared Krell FPB 250M to the FPB 200 and the monoblocks were much better. I am now using three 350 MCX. I don't know much it would cost to remodel the fireplace to fit the 400 but it might be cheaper to get the monoblocks and better as well I think there is used pair being sold here.

I was wondering about this myself. I currently have the 400cx and was thinking about the 450mcx - huge price differences. I called a dealer that sell both of these amps and I was told not worth the extra money for the monos. There will be no gain in performance what so ever. I would also like to hear from someone actually own the 400cx then upgraded to the 450mcx.

I once had the 400cx. I liked it alot so I upgraded to the 450mcx. The difference was easily heard with more bass, bigger soundstage, and less strain. Yes I thought the upgrade was worth the money but I also had speakers that were hard to drive.
I was using cast cable with both amps. I guess it would come down to your budget.

You will have problem here, does not mater with mono block or stereo amp, because you have to run the cable from your preamp to that mono block any way. So why don't you run speaker cable around the fireplace and all the components in one side instead the CD player and preamp one side then amps and speaker on both side? waste money, and don't ever change your system if it sound good to you just leave it and enjoy instead. I did make the mistake and it does cost me alot to fix it, by upgrade the speakers then the amp is not enough power to drive it then it cost more than I thought, but I fix it, never tough it again.
