I finally remembered to check the temperature of my Apollo after playing several CDs and found that the top of the case and lid was slightly warm. The CD was less so. One thing I wonder about is that the original Apollo, which is what I have, has a larger case and may do a better job of venting the heat generated by the transport and built-in DAC circuitry. But that's pure speculation.
Hopefully someone with an Apollo-R will reply.

Tom
