Krell EVO-1, FPB-750MCX or EVO-900


HI all,

Would like any feedbacks in upgrading or to stay put...
I currently have a pair of krell FPB-750MCX with Evo-202 pre driving Revel Salons ( 86db @6ohms). Love the current sound but have the itch to upgrade either the Ev0-1 ( 450W ) or the Evo-900 and worried if the Evo-1 having less power will not able to drive the Salons properly. Ive been told the Evo-1 will do the job OK and sound much better that the EVO-900 since it's Class A compared to the 900's in Class A/B but my 750MCX are also in Class A.
Just don't want to make a mistake so any help here appriciated.
Cheers in advance.

I would stick with your 750 mcx amps for sure!, doing what Rminsf is talking about would be a win, win situation, I know, I did all that he said, except the 220 yet, it's like a whole new amp indeed!, I do not believe their would be a competition if your 750mcx got new caps and a tune up with diodes and transisitors against a msb amp by no means, really, you would not convince me of that!
It is my opinion, The 700cx and 750mcx amps are some of the very best krell amps ever made, what do I know?, I do know what my ears tell me, might be my preferance, but in the end, if it's in my house, that's what counts.
I agree completely. There are many things that are necessary to make the 750mcx achieve their full potential:
a) Each one with a dedicated 20amp line
b) Directly into the line, no power filters
c) 220V
d) recapping by a Krell dealer
e) top amp stands such as SRA, HRS or Finite Elements
f) great interconnects and speaker cables such as Echole Omnia and Kubala Realization
g) My Krell dealer installed furutech power cable plugs, so I will be trying different power cables.
h) Have great front end, preamp, speakers, cables, room...
Do most of this and the 750mcx are really amazing!

Have been pondering a similar route myself having sold my 700cx to fund a loudspeaker build, will be looking at either a 750mcx or EVO 900 in the new year?I liked the 700cx sound and wondered how much more the 750mcx will offer. I did hear that the EVO 900 uses some surface mount components and may be more dificult to repair / service?
I have the 650m monos and was considering evo 1s as well. Looks like everyone likes the 750 better than the evo 1. I like the 650m because I can put way better power cords on than the stock Krell ones.
