Ayre C 5xe Universal vs. Cary 306 SACD

just back from the LA 2006 HT show.
lots of Ayre C5xe get used by the exibitor, non Cary 306.
so I have them to play my favour track on the Ayre. it is very good sound. in fact, any other rooms without it always sound a little "not right" for me.
oh yep, they sound very good, but just feel it is not quite emotionaly involved like cary. I could be wrong since I can't compare them side by side with the same other equipments.
my JC-1, Calypso with Mullard 10m + harbeth super HL5 with Cary 306 sound just soooo good and it would be the best sound if it out there on the show

Any opinions from experience on the 306 used as a decoder for external digital feeds? And does this machine have a true balanced analog architecture to go with its XLR outputs?

Yes, it has true balanced analog architecture. There is a wonderful review of the 306 in this month's TAS. It is a great machine.

The only concern I would have about the Cary 306 SACD unit at this point would be reliability, as it runs quite hot--apparently. Doesn't greater heat increase the chances of damage where delicate SS circuits are involved?

No heat problems here, standard Billy Bags rack - adequate ventilation.

Keep in mind that any semiconductor, even commercial grade is rated to at least 70 deg C, most are rated to 85 deg C. That's 185 deg F, which would be pretty darn hot.

The unit does warm up, but does not get hot to the touch.
