I've got the C2200 and used it first with Bel Canto Evo200.2s., two of them. Absolutely gorgeous. I am now running into powered Linn Artikulats--same result. I've also heard this preamp drive the MC402, a Mac solid state amp, lots of times. I sell the stuff and it was how we demonstated the C2200. Again, sublime. I'm probably going to put my C2200 up for auction, however, as I'm intrigued by the C2300's upgraded phono section. It's not clear that the C2300 is any better for the line stage. The guy at McIntosh said he's pretty sure he heard that the line stage measures better but he'd not heard it himself to say it was any better than the C2200. The McIntosh specs that I've seen don't seem any different.
