I don't have a comparison between those two, but I was in a shop that carried McCormack and Linn, I compared the 225 with the Linn AV-5125, it's a 5 channel amp. They were very close in sonic signature on the system I played them on. I had a couple tracks I was playing, my wife liked both on the Linn and I liked one on the Linn and one on the 225. All that tells you nothing as a comparison between the two in question...but I thought I would share my experience.
I can't give much info outside of this as I wasn't familiar with the system they were used with.
