Are any of you using portable DVD players to listen to your CD's?I understand that some of them have digital outputs,so that you should be able hook up to a DAC / Headphone Amp.

I'm not using it, but this one was recommended. It has no screen and a coax digital output.

It says the digital output is 5.1 when connected to a home theatre. CDs are probably 2-ch, although I don't know exactly how it works.
