I am always hunting for older DAC's/CD's with multibit chips, that I can mod, listen, re-sell. Well, today I just paid on eBay for a Parasound P/DD-1500 Digital Surround Decoder - supposedly new in box. Features 20 bit Zoran 38500 Dolby Digital Decoder, 20 bit filters 20 bit Burr-Brown PCM-63-J D/A converters (L, R, C channels), Burr-Brown PCM-1702 D/A converters (left surround, right surround, and low frequency effects channel), Low jitter Crystal CS8412 digital receiver, Independent regulated power supplies, 32,000uF Main Power Supply. I will definitely use it in pure stereo mode. Now... does anyone have a Service Manual or even Schematics for my new toy?
