New McIntosh system problem... need advice


I've just assembled a new Mcintosh system consisting of a C220 and and MC352. I was replacing my old Arcam alpha 7 integrated amp, which has served me well, in preparation for upgrading my B&W DM602 speakers to something larger (probably B&W 703 or 804). I have kept my Arcam alpha 9 CDP.

My problem is that I don't feel the extra $6000 of amplification has actually improved my sound. The midrange, and especially low-range frequencies definitely have more weight and richness, but the higher frequencies are really lacking. In comparison with my Arcam amp, there is very little detail or clarity in the highs. This deficit is as dramatic as the improvements in the lows.

Does anyone think think this is typical? Is this the "tube sound?" I'm using the same cables when I A/B with the Arcam amp, so it's hard to imagine the problem lies there. Could I have defective gear? I bought it gently used, so I can't really exchange it. I would love to get some input on others' experience with these components, and also advice on which of the two amps might be more responsible for the problem.

Thanks!

I think what you're hearing is primarily the McIntosh sound. It is more laid back and in a way less detailed. At least at first it seems less detailed then later it seems normal, like real music is supposed to sound. If you have trouble with being bothered by treble and harshness the McIntosh effectively takes care of that. For some people it's a less detailed sound and other, such as myself, it's a great sound, reminiscent of the analog of old.
It should be. No power conditioners. Also if you have a source with a volume control or passive volume control,I would try a the signal direct into the amp, skipping the c220. I have an MC402, which is very similar to yours, and it sounds great, no problem with the highs.
I too owned the C220 and MC352 combination with B&W speakers. I love the musicality of McIntosh equipment but wasn't hearing quite enough detail / clarity for my taste. My solution was to upgrade to the C2300 pre-amp, and I now couldn't be happier.
Wow, lots of great advice. Thanks! I'll definitely look into some new tubes. The previous owner estimated less than 200 hrs on the c220, so I didn't think about it, but who knows. It's true, I'm definitely used to a more detailed sound from the Arcam, even though I can now see other things I was missing. I do have a B&W subwoofer hooked up, too, so I can appreciate the added low-end I'm getting. Does anyone have suggestions for other preamps that might pair well with the MC352 in terms of extending the highs and brightening it up a little?

Thanks
