Mine runs cool at my normal listening volume and only gets warm if it's run hard for a while. It's never been hot to the touch. I think it runs very cool compared to other amps. Have you eliminated an impedance mismatch as the culprit?

Hello there, I just had my Mcintosh MC352 biased and checked out but it still runs a little hot..... I put an electric thermameter on the heatsink and it read 92 degrees. Chuck at Mcintosh said it should be fine but I'm wondering if your amp runs that hot too. It gives off heat like a small tube amp.
