I own c2200, mc2102 and mc275. The difference is power, running into nht 2.9 or 2.5 , 2.5 is 1db less efficient 86 vs 87 and the 275 and 2275 come up a little compressed at max volume(below 3 ohms is easy for all). The sound is very similar until you reach that efficiency point(275 and 2275 put out 100w (120-125w for 2102). IF you use gold lions kt88 or TS 6550 solid blacks you regain some of the dynamics but not much more watts assuming tubes match and bias is adjusted, VERY nice mac techs rebiased for my precious old tubes for free when in for a check up. Audio Classics is class and ernie has been patient and knowledgeable when I demoed.If you run only a cdp the 275 sounds very good with nos 12ax7 in spot #1.
Mcintosh 2275......c2200, mc275 differences ??
Anybody compared these two set ups, I called Mcintosh because it has been said on these forums that the two are the same, they said they are not, they are different, any thoughts on sound comparisons ??
