Primaluna Prologue Premium CDP

A lot of players heat up the discs pretty good. Normal stuff, I say.

Ive never experienced a heat up issue with a solid state CDP....... 

I've owned a PrimaLuna CD player for almost four years.  Use it daily.  After an extended session, the discs do seem to become quite warm. If you're concerned about possible ramifications/complications, contact Kevin Deal at Upscale Audio.  (I suspect the warming is normal for the machine and poses no serious problems.)
