Best Amp for McIntosh sys.- MC252, MC402, or MC501


I am upgrading a system that I have for about 40 yrs. Recently purchased a MCD301 sacd/cd player, MR85 tuner, and Paradigm Studio 100 series IV speakers. Still have C26 pre-amp and MC2505 amp (both recently serviced by MAC). I am happy with the sound but am afraid the days of shipping the amp back and forth for service are limited. The spks are rated "Suitable amp power range 15-350 watts" and "Amplifiers that exceed-power range are recommended". I don't intend to make another amp upgrade and am leaning toward the 501.

From the 252 on up, to the 602, on the Paradigm 100's each level up surpassed the former. The 602 sounding the best... IMO.

Personally, I could have lived pretty eaisly with the 402... on the 100's. Primarily due to the expense of the speakers. I'd not likely go with the 500 mono's either, again, due to the relationship of amp cost to speaker cost... BUT... if it's all about sound and there is enough $$$ in the till... with having the speakers already on hand and not wanting to exchange them out again, the 402 or larger Mac amps would definitely be worth checking out.

I preffered the 602 over the 500's, myself on those speakers.. Additionally I liked the large Mc floor standers over the Paradigms too with the MC602 even better. L360's I think.

Having more power on tap is not a bad thing more often than not... so there's that too.

Good luck..
I totally agree with Jim. The 252 would work. The 402 would be great and more than enough power. The 602 would be like the 402, but even more. The 501, in my view, would be too much money spent on amps for those speakers,

I would add a question for Golf: do you envision yourself changing speakers in the not-so-distant future? If so, might want to think about which speaker + amp combo you will be shooting for. This combo is arguably the most important part of the system, so better thought of together.

Sorry to complicate things for you!
Go with the MC501 monoblocks. An entirely different level over the 2 channel amps. Much better seperation, imaging, and dynamics.
Of the 2) 2 channel amps listed I would go with the 402. I have one and love it. I had a 352 and really didn't expect much when i bought it I just wanted to get away from the changing of the bulbs. But the 402 is a newer design than the 252 and has a few differences that add to a better sounding amp. One is the newer design power supply, to which accedit the better sound over the 352 I had. And second is the "quad balanced" circuitry also referred to as "dual differntial" in earlier Mc amps. This lowers the noise floor of the amp.
