Amazon review.

The '83 decodes all advanced audio formats: Dolby TrueHD, DTS HD Master Audio, etc. So the lossless audio is available via 7.1 analog outs as well as PCM over HDMI. You don't need an A/V receiver that includes decoders for these formats - the player does the work. Speaker management provided by the '83 makes the 7.1 analog outputs usable, but with some limitations: The bass management frequency is fixed at 80 Hz, and there are limitations to speaker distance delays.
