Thanks. With the latest May 4 firmware, the BDP-83 recognizes the one HDCD I know I have. When set to bitstream, digital coax gets something that the Outlaw 990 deals with reasonably. The 990 does not have an HDCD decoder, so it should just interpret undecoded HDCD bitstream as a standard 44.1kHz/16bit CD.

The alternatives will be whether the Oppo decoding HDCD through the stereo analog to the 990 in bypass is better than the Oppo decoding HDCD to LPCM (44.1kHz/24bit or whatever) and going digitally through the 990's DAC in stereo or upsample.

For a couple of HDCD's it may not be worth spending the time to figure out!
