Portable CD player with Digital Output

Check out the I-river Imp series. The cd player I have from them, the imp 550 kicks serious butt. I can't say enough about this cd player. And it has line out and optical out. It is also razer thin.

The Sony definitely has an optical out even though Sony elects not to reveal this on the website!! It is an auto selecting optical out so when you hook up the DAC it automatically switches. As a transport it is a good machine according to all who use it with a DAC - I am still waiting to receive mine.

I believe Denon portable DCP-150 has a digital output, besides having great sounding reviews. I have the DCP-100 btw.

Second the i-River. Have one without digital out and it has as just a player trounced separate players, no really. Can only imagine what the dig-out version will do.
