Can't you use a Oppo BDP-83 with its' analog outs to go this route? Do the new high bit rate audio codecs play over the Oppo's analog outs?

No they only play via HDMI, thats why the market has crashed on pre HDMI gear, between 1080p and the latest codecs
.
This is confusing.
Full on HD audio doesnt come out of the Oppo BDP 83s analog outs?
Hdmi ONLY? That doesnt make sense to me.
So then
the full on HD audio only comes out of the processor in a dedicated HT multi ch proc or recievers analog outs, and NOT from a capably equipped source unit?
It has to.
Ive not yet seen amps with HDMI
. At some point the digital HD AUDIO INFO has to be converted to analog
be it at the proc/receiver or at the source.
The BDP 83 has the codecs for HD audio too.
Id bet the Oppo also allows for true HD audio out of its analog audio connections.
It has to be so. Processing of the Dolby and DTS HD audio is processing that info into analog. We would not be able to realize that sole benefit if it were to remain in the HDMI arena only.
The reason for the Oppos HDMI & multi ch outs is for flexibility with interfacing it into a greater variety of downstream appliances, and configurations.
HDMI has its own feature set for both video and audio, respective to its class
1.0; 1.1; 1.2; etc. Only the bandwidth increases with each subsequent iteration. Due to the bandwidth increases, other audio aspects were then enabled
like DSD, multi ch audio, and now true color and HD AUDIO to be passed along a single cheap cable.
UNTIL hdmi 1.3 CAME ALONG YOU WERE ONLY GETTING STEREO AUDIO. 1.3A ALLOWED FOR STEREO dsd DIRECT WITHOUT IT BEING SWITCHED INTO pcm, AND THE hd color and audio facets. The video side also got a step up enabling True color.
Now networking is being added in the 1.4 version.
However capable the HDMI versions may well be in terms of bandwidth capacity enhancements, it remains the province of the displays, processors, and source units to be likewise outfitted or capable.
Not every source unit has the higher res audio or video codecs even if it has HDMI. One has to check which version of HDMI is on board. If its Blue Ray and doesnt have analog outs, it likely doesnt have the HD audio codecs needed to realize the better audio Blue Ray affords., and serves only to pass them along to the processor. If it does however chances are quite high that it does have those codecs and the only likely losses one could suffer then would be True color if the display doesnt have the same level of HDMI gbuilt in. No such losses should occur if the sources analog outs are employed, either by way of a receiver or right out into a multi ch amp from the source unit.
My Oppo DV 980H has HDMI 1.2. Upscalable video, and multi ch audio on the standard 19 pin HDMI cable. No true color video, DSD (SACD audio without conversion, and 24/96 multi ch audio , 24/192 in 2 ch though).
Blue ray dictated greater needs in thruput to accommodate more audio and video info, so another iteration was added. And agan, the technology preceeded the implementation of its benefits as the software lagged behind as usual.
Checking the capabilities of each source item, and processing and display device will tell you which way to proceed downstream of it. . that and your current devices of course.
