[HELP] AUDIOPHONICS I-Sabre V3 DAC ES9023 TCXO

So I have a question about this DAC -- I finally got mine (and a raspdac enclosure). Is the DC connection on the DAC itself also supposed to pass through power for the Pi? That was my understanding, but when I supply power (I ended up getting a 8V/2800A linear power supply) no lights come on on the Pi and I have to power it separately. Which doesn't make sense as the enclosure doesn't have a place for the other power cable to enter.

However when I look at the video review on the previous page, the reviewer makes comments starting around 1:50 that the Audiophonics doesn't supply power to the Pi.

I've opened up an email with audiophonics support as well on this issue.

But do I potentially have a bum board or did I not understand how it works?

(Also all of that being said, I was able to hook the system up for a test night with power to the Pi and it sounds really good, and I was really impressed with how easy runeaudio was to setup and get working with the DAC.)

Yeah, so I eventually figured this out. I had just taken my DAC and plugged the GPIO pins into the Pi, and assumed that if the button wasn't there that the power would just flow if supplied power to the DAC over DC. I wasn't thinking that the button acted as the circuit to actually pass power to the Pi, and that it was more to turn off the power to the pi (or allow it through.)

Once I hooked up the button (and pressed it) it worked fine. LED is working fine too.

So again, just my lack of understanding of electronics in general, I think. This is literally the first thing I ever put together that involved wires or components, I'm much more of a software guy.

Thanks for offering to help, tho.

Has anyone tested the v3 against the v2? Is it work the extra in terms of sound quality?

So I've recently got the Sabre V3 DAC and a raspberry pi, but haven't gotten a power supply yet because I don't know which one to get.

This might be a dumb question but, what would be the difference between getting one of these power supplies

which costs about ~$20

or the one linked above which costs about ~$120. (http://goo.gl/zKv4im)

For the raspberry pi DAC setup?

I'm guessing it has something to do with "electrical noise" and sound quality? I'm no audiophile or an electrician so I don't know much about this stuff, I'm more of a software programmer kinda guy. But would that be the reason?

Maybe if someone can explain or point me in the right direction? It would be useful for other people who stumble upon this post to gain some knowledge as well Thanks!

P.S. I guess my best choice would be to simply buy the cheap one and see if I can hear any noise. If I do, then start looking for better power supplies.

Is there any easy way to add IR sensor to the AUDIOPHONICS RaspDAC Kit enclosure?

I suspect answer by PeteB from still stands?

Would the enclosure be able to take WD Pi Drive?

Thanks
