If you can afford the McIntosh you will never regret the purchase. I'm currently using the MC275/C220 combo with great satisfaction. Most people who purchase the C2200 seem to to be happy as well. The C220 is less money and and is close in sonic character. Many feel that the C220 is a little smoother with better bass, and that the C2200 is slightly more detailed. I never compared side by side, but have listened to both and am very happy with the C220. I've never heard your speakers, but the Triangles I have heard are an easy load and would be fine with the Mac combo. Good luck,
