Any body have experience with OPPO BDP-80?

Yes, the digital multi-channel can go over HDMI to a receiver capable of decoding it. The SACD can be sent as PCM or DSD. I think DSD sounds better. Your processor has to have the capability of decoding DSD via HDMI or will default to PCM. Either way the processor is doing the work of the Oppo. Or, you can use the analog outputs from the Oppo. In my case, my receiver is a better decoder. If your receiver or pre-pro handles True-HD and similar hirez signals, then the HDMI will carry all the digital outputs from Oppo. My Onkyo locks onto the signals without problems or dropouts. The Oppo is very reliable.

Mceljo,
Also, if and when monies become available, JT of Exemplar can make your Oppo the 'Best Sounding Digital in the World'...at least the best that I've personally heard.
It's true. For $2500. Exemplar rips out the lesser parts in the audio section and creates a digital god player. Actually, killing my Denon 5910, also an Exemplar upgrade. Makes mine sound broken. WOW.
For anyone looking for digital, NOTHING I'VE heard comes close to this...
Good luck and good listening Mceljo.

Mceljo,
I didn't make this very clear...the $2500. includes the price of the Oppo, $500.
Maybe, and I can't know this, JT would take your player later and upgrade it? Who knows...doesn't hurt to ask though.

I don't see myself ever spending $2,500 on any type of CD player, simply too rich for my blood. That's nearly a factor of 10 off from what I'm spending.

Ric Schultz at tweakaudio.com has an incremental price menu for mods of new Oppo BDP-83 and the even newer BDP-83SE blue Ray player.
Not too much has to be spent to gain significant initial benefit, with the option for more expensive prices if you need better/best.
