"Upgrade" C-J MF2500A to Pass X250, SimAudio, Or?


I currently have a C-J MF2500A, Cary SLP98, Cary 303-200, Fanfare tuner, etc. driving B&W M802 S3's, in a 12x16" room. I'm actually fairly happy with the sound, but have the upgrade bug; you know how it is. The B&W's like plenty of power, so I'm thinking of high-current SS amps. For some reason I've always had an urge towards a Pass Labs X250--but would that be an "upgrade" to the 240w MF2500A? Also, I've heard that the Pass Labs amps really need balanced IC's to sound their best, which my Cary pre-amp doesn't have. I've also considered Sim Audio, Plinius, or one of the newer McIntosh amps. I'd buy anything I get used. And weight is a factor--even the X250 is twice the weight of my C-J amp, so I don't want to go much over 100 lbs., max. Thanks in advance for any advice!

I have listened to or spent considerable time with all the amps mentioned. The MF 2500A is a keeper and you will be unhappy once it leaves. You will not be able to replace its specificity and openness. This is truly the anchor to your current system. I would look at a different preamp or speaker first. Hang on to the Cary CDP. Alternatively, start with cables. What are you using and what have your tried?
Cellorover-

A different preamp, really? Just curious- what do you think would work better in that setup than the Cary SLP98?

I don't own the Cary, but it is one damn fine preamp.
Thanks for the question Danlib1--

My only intent was to state...keep the CJ while offering some upgrade bug remedies.

But you asked a good question. Is there a good answer? Who knows. My ears tell me that I like CJ, BC and BAT better than Cary. The very same ears told me that the Cary SLP98 is lovely, but not for me. I found a little something more that I liked in each of the other preamps in my system. But alas, I no longer use a preamp, so I have found a cure for the preamp upgrade bug.

If Steveaudio has the bug, IMO, there are choices to be found by keeping the CJ 2500A. Since I do not know what he is looking for, I cannot be any more specfic.

Me? I have gone minimal and listen to music. I found it hard to reach this point and very tempting to ask is there something else.

Steveaudio, take the cheap, fun, frustrating, exciting, overwelming cure to the bug. Keep it all and buy some new wires or send you children to college. One of these will kill off the bug fast! Cheers!
Cmach, that's great that you're using such high-end electronics with the Sig. 805's. The more I get into it, the more I think the upstream components are even more important than the speakers.

I'm sort of agreeing tho with people who say to keep the C-J amp. It occurs to me that I may have maxed out with this system--in terms of probably having to spend way more to really improve upon amp, pre-amp, or speakers. I mean, what would I have to get to significantly better the M802's in a full range speaker? (And with all the dues involved in selling & buying large speakers, etc.)

BTW, my cables are Nordost Blue Heaven IC's, & Cardas Quadlink 5-C bi-wire speaker cables.

Thanks for all the advice!

Don't stree oout with balanced connections. The pass x250 can sound great with tube preamp without balanced output. I prefer certain tube pre over X1 with my x150. don't know about CJ2500 vs x250
