Yes.

No, remove all jumpers. See page 20: you're using TTL level S/PDIF.

So, when using the single SPDIF converter I can use any of the 8 inputs? The SPDIF auto detect feature will choose. Should input remapping be on?
Thanks, Mike

Those files are un-open-able.

No they are not. You just need a workaround :

Download all files and then rename them by removing the last 4 characters (.zip) from each file name. Then unzip the first file, the others will unzip automatically. I used 7zip for this, but windows standard zip will probably work just fine. I split them into multiple files because the file size exceeded the maximum allowed file size for uploading to the forum.

Most components in the design are grouped, but you can blow them up into smaller grouped items. Such a the side panels, front panel, back panel, volume control, placid HD etc.

I would like to share how I use built from TPA components DAC in simple stereo mode. My DAC is connected to SPDIF output of OPPO-93 Blu-ray player which works as media server. I have all my music ripped from CD's and DVD's into FLAC files and stored in 1TB portable hard drive that is connected to OPPO-93 player via e-SATA interface. In this set-up I can play music up to 24bit/192Khz resolution (SPDIF limitation). If I want to play higher resolution files then I will have to use OPPO's internal DAC and analog output. For now I have no higher resolution files than 24bit/192Khz. It is simple solution and works for me, no USB or network connection is needed. I can also stream music from my computer using wi-fi or wired network connection with the same resolution as an option.

Does the Buffalo DAC sound better that the OPPO-93? How are they different?

I am not an audio expert but I can hear the difference. Buffalo sound is more detailed and sound stage is better defined. I will be mad if there is no difference after spending so much time building this DAC. There is no huge difference but it is noticeable. My primary reason to buy OPPO-93 player was for their support for FLAC files and other media files, e-SATA port and network connection, the rest is a bonus. I can verify sound quality by switching between digital and analog inputs (which I built into my DAC) when playing the file.
