no, sorry. Looking at it from a pure technical point of view the Oppo would have a better SNR going straight to an amplifier than going through the CX-A5000 as its analog circuitry is higher quality due to the better DACs and the way they are configured. Whether or not that is noticeable is another story. From my brief listening experiences with the Yamaha, without even attempting to use YPAO or the PEQ, I haven't even bothered to hook up the analog RCAs from my Oppo, as the CX-A5000 sounds so good. I will be hooking up the XLRs though, maybe this weekend, to see how the balanced approach works. The THD and the SNR specs for the CX-A5000 are excellent and I believe are worst-case specifications. I believe they will test better than that. The Oppo BDP-105, according to these Audioholic measurements are off-the-charts excellent. The THD for the Oppo measured .005 and the THD for the CX-A5000 is .008 or less! The SNR for the CX-A5000 is 112dB or more! If you check out the excellent article from Dr. Rich at Secrets of Home Theater and High Fidelity: Audio Video Receiver Build Quality - Part 1 you can see where the Yamaha would likely be placed in comparison to others. The top DACS in the chart are what is in the Oppo BDP-105.
Do you know if the Yamaha has a better analog volume control?
I am fairly sure that my Marantz AV8801 digitizes the XLR inputs because it can do LFE+Main processing to send a copy of the main bass to the sub. This feature is not available for the 7.1 analog inputs. I do prefer the 7.1 analog inputs from the BDP-105 and this might be the reason.
It is always difficult to know what the processors are actually doing. If processing is available on the XLR input they can be digitized.
The question is, in Pure Direct do they remain in unprocessed, remaining entirely analog.
