Thanks guys, two very interesting posts. My Yamaha AVR has Burr Brown DACs on all inputs too.
I'm glad the DAC magic has been mentioned as I have an 9 year old Yamaha CD player (CDX-496) that I plugged in last night connect via analogue and put it up against my PS3.
Richersounds stock both, so hopefully they'll have both in at the same time and I can arrange for a listen and hopefully they'll be accommodating enough to let me bring my old CD player so that I can plug the DAC Magic into to do a three way comparison.
Check this thread for my opinions on the old CD player vs PS3.

Maybe a DAC Magic is the way to go, it'll be interesting to hear the differences.
