Primaluna Prologue Premium CDP Heat Concerns

Gday, I purchased a Primaluna CDP about 6months ago. It had never been taken out of its packaging, so as far as I'm concerned, a brand new unit. 
After some lengthy listening sessions,, I've noticed, on ejection and retrieval of a disc, it is worryingly warm. Almost hot... 
Does anyone have similar experience ?
I spoke recently, to someone, who said, this was/is,a known issue. 
I have contacted Upscale Audio, but still waiting for a reply. 
Im wondering if this is why Primaluna dont make cdps anymore. 
Any experiences or thoughts and advice?? 
Cheers Andrew
