    I got a bonus at work today and decide to do something potential stupid. I've always liked the look and build of the NP-S2000 but its limited because it doesn't support MusicCast and/or there's no digital coax in.

    But was bored tonite and just read up on its internals. Dual Burr-Brown PCM-1792A DAC. Nice! Read the spec sheet at http://www.ti.com/lit/ds/symlink/pcm1792a.pdf and its a pretty simple interface, spi control/i2s data. Then I came across some hidef photos at https://www.hifishock.org/gallery/electronics/yamaha/source/music-server/ and saw this one. Its the controller card.

    The lower left corner connector goes to the DAC board. I see they list the chip select right and chip select left. these must be the SPI control lines. I'm hoping the other ones are the i2s data lines. So I said what the hell and ordered one of the refurbs from Accessories4Less. I'm going to try to connect a SPDIF to i2s board to those pins and see it I can turn this into a usable DAC. Hope this works!

    Edit: change i2c to i2s

    It's a great unit. I have one and love it. Make sure you update the FW to the latest version if it has not already been done. I think it is 3.10? This document says 3.00, but I know they came out with more after that. You'll need to make sure it is accessing the internet. If you can get Internet radio, then follow this guide and it should update you to the latest. 192KHz....

    If you can mode it, which is possible, to have selectable "use as external DAC input" or the "internal 2000 functions", I would do that. This unit does FLACS (and MP3) extremely well. As you can see it is built like at tank. Wait to you go to lift it up! LOL.

    It be much harder to keep the existing internal functions. I'm hoping I don't need to de-pop or blue wire any parts, that way I can put the device back to stock mode. All my rooms use MusicCast and its nice that I can link them, so I'd probably use a WXC-50 to this.

    I have called Yamaha since 2014 for a service manual. They never made one for this. I always get service manuals. Kind of strange, Yamaha is always on top of their manuals and they are all first rate.

    If you some how "magically" come across one, please let me know.

    Thanks.

    This guy is selling the service manual. https://www.electronicsrepair.net/ I'm reading it right now. I don't feel comfortable giving it away because my info might be embedded in it but $10 was quite reasonable.
