I had a C2200, my first Mc piece. It was referred to my by Frank Gow (RIP)and he stated that was his favorite McIntosh piece. I bought it, replaced the lamps with LEDs (a kit from Audio Classics). The C2200 was at one time the best tube preamp McIntosh offered. I have not owned the C220, but now own the C2300 (traded my C2200 for it). Tne MC275 will mate very well with the C2200, which is what I would recommend between the two preamps. The C220 is the entry-level rpe in the McIntosh lineup.
