Upgrade to McIntosh

All tubes here. I have the MC275 VI paired up with a C2300. Listen to it most everyday in my office. I added a RME DAC so I could hook up my streamer. I have a 10x10 room and while I don't listen at reference levels (more in the 70-80dB range ), the MC275 has plenty of power and low end for my Paradigm Studio 20V5s. Whatever you pair with the MC275, the MC275 will not be the weakest link in the chain and is an amp you can keep and enjoy for years. 

@wolfgangamadeusaudiophiliac I haven't compared that DA2 module to other higher end (above $1000) DACs. I've only owned a couple of the Schiit Audio DACs (Modi and Modius) and the module in the C2700 is certainly better. 

This will certainly be a personal choice and I do understand the dilemma. McIntosh does sell the C22 tube preamp without a DAC if a McIntosh tube preamp is your interest. Then you are not tied to a built in if you want to try out others. I might eventually switch to another DAC, but the DA2 was a big improvement for me over what I currently owned.

I have been a long time McIntosh fan and have run MC352, MC601's, MC75 III, and currently MC275VI.  Surprisingly, a Don Sachs II pre amp absolutely out performed my beloved C500T pre amp.  Suspect 6SN7 based system is just better than 12AX7 to my ears.  I ran Cremona Auditor M's, then Guarneri Evolutions and both were excellent.  A move to a much larger room allowed me to run Cornwall IV's and I have no interest in changing anything.  Don't overlook the Don Sachs / McIntosh synergy.....a wonderful match.  Have fun!

I second what you said. I'm running a C2300 with MC601's and I get wonderful, warm tube sound with lots of bass. I also have an MC275 in my system and I can switch between the 601's and the 275, and the difference between the SS amps and tube amp is definitely more subtle than when I had a SS preamp with the same amps.

Interesting you ask. I went down a whole rabbit hole trying to go with bookshelves on speaker stands, + a wireless sub, due to my room limitations. and I was very disappointed by the sound - it was very “small and narrow”. My room is about 20x18. I found the spendor A4s and went with those (the footprint of the A4 is **SMALLER** than that of any speaker stand base). I personally am deeply satisfied with the A4 (could have gone A2 but I got a deal) + subwoofer combo. Depending on what I am listening to, I will or won’t use the sub. The splendors powered by the M352 provide a wonderful, lovely, crisp sound. For “critical listening” I use the built-in headphone functionality with my focal MGs.

how big is your room?

it goes without saying, part of the appeal of the 352 is the simplicity, and the look, which in my case this is my living room, I don’t have room for 2-3 components and it’s wife-approved, were also key. But IMO, the 352 provides specTacular sound in addition to the aesthetic.
