I have your Pioneer Elite player I think (it was for SACD and DVD-Audio). It had some sort of FireWire connection so that if you had the matching Pioneer AVR, the combination, while being mid Fi, was superb. If you wanted to play a movie you had to disconnect the FireWire and connect HDMI so eventually I just added a cheap Sony BluRay in that system and used the Pioneer for music only. After more than a decade I upgraded the AVR and lost that proprietary FireWire link and used HDMI for the multichannel music from the Pioneer player. It still sounded very good but some of the magic was gone
