I purchased my OPPO-205 expressly to enjoy 5.1 SACDs via OPPO's DACs outputting to a Sony 5.1 Analog Preamplifier TA-P9000ES. Glad I bought the OPPO, since now there are no longer any internal DAC 5.1 SACD Players out there, in fact, there's only one means to enjoy 5.1 SACDs in USA today, a DACless Sony UBP-X800M2 Universal Player which must be connected to an external multi-channel DAC via HDMI. For that connection I would need to buy a new AVR, or Pre-Pro. At any rate, I have also used the OPPO to play stereo streams via usb from computer to OPPO and I have played multi-channel and stereo music from flash drive to OPPO too. Both suffice but the usb connection does not link to OPPO's bass management control, which precludes proper bass integration. I still enjoy movies from DVD, Blu-ray, and Ultra BD discs via the OPPO and I am pleased with its no glitch performance.
