Upgrade to McIntosh

You cannot go wrong with McIntosh separates. Ignore all the ridiculous naysayers on this site that claim otherwise or who make up rumors they cannot defend. I have a C2700 with the DA2 module feeding into two MC275s for my LaScala speakers. It sounds fantastic for everything I play on my system, and I play almost ever genre of music out there. The bass with the MC275s are great. You do not need a SS amp for good bass. However, if you really desire that deep heavy bass, get a subwoofer to supplement. 

Vintage is the way to go! Marantz tube gear is great! mc30 and mc225 are my favorite Mac amps. I’m tinkering with HK citation 1 and 2 sound really good too! 
 

@audioman58 I’m not surprised! I don’t like how McIntosh uses circuit boards in mc275. That type of money should be point to point. They must get parts from China because most manufactures do. Assembled in the us. 
 

glowing green leds under the tube are kinda silly. My wife didn’t like that at all. Happy wife happy life lol
 

overpriced, McIntosh vintage gear sounds good. Mx110, mc30 mc225 mc240. Not my favorite can’t beat it if you get a good price for it.

I don't think any of the McIntosh amps preamps power conditioners receivers cd/sacd players are made in China. It is only their small powered speakers and some speciality items. 

McIntosh has been having their hybrids made in China and  then reinspected in the U.S and  some amps That Don’t have the autoformers .  It’s now more about business and $$ profit  the original owners were Audiophiles 

now I believe S Korea owned .

My two cents: My instincts are to go with the separates in this case and, for that matter, in most cases, in general. However, either of these 2 power sources would me more than adequate for the speakers involved. I haven't heard the MA352. However, a friend and I spent approximately 4 to 5 hours of contiguous, concentrated, serious seat-time with the MC275, critically listening to several pairs of tower speakers I was in the market for at the time. I can't recall what pre-amp was being used but it was a MAC. There is no question, IMHO, that this is an outstanding sounding amp. I would expect that the MA352 would be just as impressive with the speakers involved. In the OP's position, I would plan to schedule some serious seat time A/B'ing both power sources and insist upon doing this with the speakers involved (e.g.  not something similar).
