McIntosh MC275Mk4 with a pre or Mcintosh 6900?


I used to run my Mcintosh MC275 with Mcintosh MHT100 as a pre, which probably wasn't a very good idea - now in my new apartment MHT100 stays with the home theater set up in the living room and MC275 moves to the study as a possible basis of the new stereo system. I'm considering Sonus Faber Cremona Auditors as speakers. The question is: should I add a pre (which one? I have no clue) or sell MC275 and buy my old dream integrated amp - Mcintosh 6900? The latest solution is obviously cheaper but will it give me a better sound? I know it's the same old tubes vs solid state question but another thing is that I'm looking for a more dynamic, rocking sound lately...

the 6900 has autoformers, and compared to some ss brands is more tubelike. the mc275 with a c220 would also be a killer combo. i use the 275 with a c22 and it is excellent, even on power hungry gradients.
hi jaybe:

i just reviewed the c220 preamp. it doesn't sound like there is a tube in it. i own a 275. the combination is too analytical for long term listening. the only think that a combination of c 220 and mc 275 would kill is some flies.

it might be good for dog obedience training.
The 275 is a slow, gooey sound already... maybe try a better brand of amplifier alltogether.  There is so much better sounding gear out there for less $$$ than MAC.
