This is a comparison I am interested in as well. I have the MC601 amps and the C2300 preamp. I also own a number of PS Audio products to include a DSD, P5 and P10. Both are terrific companies, but I think the customer service at PS Audio is LIGHT YEARS ahead of McIntosh. Go to some of the other forums and you’ll note a number of complaints about Mac’s customer service, and a perception of “superiority” by the people at Mac. Thank goodness I have not had any problems with my gear.
I agree with a house sound to McIntosh, but the new amps such as the 601 certainly have a lot less of it. A slight bit on the warmer side, but I would much rather that than an irritating, bright sound. As the C2300 is a full tube preamp, some tube rolling can make it as warm, neutral or bright as one wishes.
With my great experiences with PS Audio, if I had to start all over again their preamp and monoblock amps would be at the top of my list for auditioning. A full PS Audio system with my Sonus fabers may be one SWEET sounding system.
Definitely agree that customer service is important and too often neglected these days, even by putatively “high-end” makers and retailers. Seems to be something of a lost art in certain quarters, for a lot of reasons I guess. My experience, reliability-wise, with PS Audio and McIntosh alike has been superb, so I’ve not had to delve into the world tech service much at all and can’t speak to that with any personal experience.
May I ask which Sonus Faber’s you use with the C2300/MC601 setup? What are your impressions? I heard some Sonus Fabers (not sure of the model) with the even-bigger McIntosh MC1.2KW (I think) at AXPONA this year, and it was very nice indeed.
By the way, I’ve upgraded the stock C2300 tubes to Gold Lions, and this was a step in the direction of a bit more mellow, euphonic sound, to my ears anyway.
