Primaluna Prologue Premium CDP

ricey - I've noticed the warm discs - and given it a passing thought - but I can't say that I am concerned.  Many cds - quite a good number played many times over during my ownership of the PrimaLuna - and all is well.

Mmmmm, I'm taking on board what your experience and thoughts are, but I'll see what Upscale Audio say. 
I'll post their response, and let you all see what they say. 
Cheers Andrew

I've been running a PrimaLuna ProLogue 8 CDP for quite a few years now and have yet to run across a noticeably warm disc but I usually change discs after each play maybe cutting back to a favorite track or two but even then I have never a noticeable a change in disc temperature when pulling it from the tray. One does have 6 vacuum tubes above the CD drive in the PrimaLuna CD players but even with that, it would take a direct heat source to even begin to disfigure a CD. Personally I wouldn't worry about it and just enjoy the music. 

I'm now wondering, if I remove the removable  protective cage, which may allow more heat to escape might make a difference?? 
Even the use of a fan...??? small fan
I run AC Infinity fans on my Cambridge Audio 851w, Oppo 205 and Denon AVR.
