Cary 306 SACD

My first discussion thread on the site!
I have had the 306 SACD for a couple of weeks now and warming up nicely. However, when I switch between redbook, HDCD and SACD during the same listening sessions, the machine just locks up (particularly on SACD discs after playing redbook) and cannot read the disc. I have to either switch off and reboot so to speak or pull out the mains socket and plug back in. The dealer said that if the machine does not have ventilation it will do this as another customer, I was told, had the same problem. I think I have enough space on the rack at the sides for ventilation.

Can any new owner explain this and any way to rectify the problem as its a pain switching on and off.

Thanks for your answer.
Mine is about luke warm as well.
It just cannot read discs when I switch various disc formats sometimes and locks up with Cary SACD 306 on the display. Also takes about 10-15 secs to recognise when it does pick up the formats. so then I have to unplug or switch on and off, is this usual?

Maybe I just pass it back to the dealer to check?

Cheers
