Oppo 103 and PWD II - coax audio worth it?

In my basic 2.0 TV setup, I'm using a PWD II dac, a USB media player for PCM files and an old Phillips DVD player, along with Quad powered speakers and a good Samsung LED TV. In looking at upgrading the DVD player and thinking about an Oppo 103 as a way of combining media playing into one unit, I'm aware that the PWD won't take the Oppo's HDMI audio line. Is coax for audio a reasonable alternative? With coax and the Oppo, one loses the Dolby HD and DTS HD audio, but I can't say I've ever had a hankering for either when given the opportunity. Thanks,
