MA5300 integrated amp.

Page 6 from the MA5300 integrated Owners Manual suggests: "Allow at least 6 inches (15.24cm) above the top, 2 inches (5.08cm) below the bottom and 2 inches (5.1cm) on each side of the Integrated Amplifier, so that air- flow is not obstructed."

My MA6600  does not get hot at the volume levels I listen to.   When I had a Krell FOB 200 I used some small usb fans to cool them.

The backs on the cabinet are removed. The heat sinks on the Mac5300 are at the sides and there will be 1/2 inch of clearance on each side. I have read that the MA5300 runs pretty cool, unlike the Musical fidelity 5si and 6si. These are others I have considered.

Any amp in a cabinet is going to run hotter than one out in open air. I have been known to take the backs off and leave the doors open when amps are placed in that type of furniture.
