Yes, but not a digital link. The simplest thing to do is to use an insert cable (TRS jack to 2x TS jacks). Plug the TRS end into the YDD-60 headphone socket and the TS jacks into the jack inputs of two channels of the D888. The jack lebelled "send" is the left channel and the one labelled "return" is the right channel, so pan the two channels hard L and R on the D888 respectively. Monitor with headphones connected to the D888 headphone output.

Thanks for the response. It was very helpful.
