the c22 commemorative is superb in every way, and the newer c220 and c2200 as well. i wouldn't describe them (or the arc's) as anything but neutral however...not like a cj or the holy grail, marantz 7.
Mcintosh vs. Audio Research tube preamps
Has anyone had the opportunity to compare, say, Audio Research LS25 with a Mac C22 original or commemorative? They have very similar values on the used market and I was curious as to anyone's perspective. Or say the LS25 (i or ii) and an MX110. I suppose I would expect to hear that the vintage Mac stuff is warmer with more rolled frequencies, but I'd love to get a first-hand impression from somebody. The LS25 mark 1 is also supposedly tube-euphonic, as well. It's a good topic for the old database!
