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 agree with changing pre tubes to start.I really like the older Mullard long plate 12ax7s and 7025s.I didnt like the sound of my 402 with a Mac preamp.You might also add a few makers to your short list on speaker replacement..Dynaudio,Focal.Im guessing its your speakers

If your Arcam has pre-outs and main-ins, then you can use its preamp output with the Mac amp, and the Mac preamp with the Arcam amp. Might give you an idea what each of your new components sound like individually.

Second, you might play around with a couple of different output taps on the amp.

And I'll second other's advice about giving it some time . . . when you've spend a pile of hard-earned cash new electronics, mental expectations can be tricky to sort through. But on the other hand . . . if you don't like it, then you don't like it. McIntosh is very fine equipment, and their manufacturing quality is definately better than what you get from Arcam . . . but that doesn't mean that at the end of the day, YOU have to like it better.

At the very least, Mac stuff holds its value very well . . . so I wouldn't regret your purchase.

The advice I read the most here is give it time and try new tubes. I am a long time McIntosh owner and just recently sold a MC352 in favor of a 402. That is a great amp, and does most things well. No amp does it all well, hence the audio industry. In addition to the afore mentioned advice, which is probably the best solution. I would add one more thing you might try. Try re-adjusting your speakers. You mention added mid and bass and that is having an overall effect on the room acoustics. Maybe re-aim them to your ear and see if you can regain or discover a new voice for the highs. You have a great front end give it time. Best luck and listening.

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.
