Does anyone have any info on the Philips CD-80xx?

You might try the attached link for more information about the Philips / Marantz CD-80. http://www.audioreview.com/CD,Players/Marantz,CD-80/PRD_116968_1586crx.aspx. Most are just reviews but there is some(limited) technical information there as well. The Philips CD-80 is the same unit as the Marantz CD-80. Marantz used the Philips name in the U.S. so if you search for info pertaining to the Marantz CD-80 you may find more info. I owned onr of these units for about 10 years loved the player never had any problems with and am sorry I sold it.

I have one. U.S. retail was $800. 16 bit 4X oversampling with TD1541K 'Crown' DAC chips. Copper-shielding in the chassis. Even has a decent-sounding remote volume control for variable output. Particularly good at PRAT, as Martin Colloms noted in his HFNRR review of the unit. Mine was modified with Rick Roberts' Simply Physics Isodrive. Decent sound both as a stand-alone player and as a transport only.
