Btw, your photos don't show a jumper across the VCC and VBUS pins on J2U. You have to install one for this test...

EDIT: Oops, we were posting at the same time.

Yeah, so it's a solder joint issue after all.

How can it be a solder joint? All i did was measure the pins to ground strips with a multimeter and it worked somehow

Didn't even go near the soldering iron. Maybe the chip was somehow stuck.

By exerting pressure on the chip's pin(s) you have made a previously-unconnected joint make contact. This is probably temporary until you reflow the suspect joint to permantly fix it.

Fair enough. I'll do it later, time to enjoy the DAC

Hello, just wondering if anyone knew if there were any places that offered the gamma-1 DAC as a kit - like the kits from Glassjar audio.

Sorry, Jeff (Glassjar Audio) has his hands quite full at the moment so there is no full kit available. Aside from the PCB and parts from me, all the other parts are readily available from Digikey/Mouser/Farnell/RS, etc. See the official γ1 website for details.

If my Mini^3 project is a success, I'll order the parts for the Gamma-1 DAC. I take it the Gamma-1 would be a step-up from my Creative soundcard? I was looking at purchasing the Musical Fidelity V-DAC, however, I presume the Gamma-1 would probably be on-par if not better than it (And I do enjoy the pleasures of DIY).

Thanks AMB.

If you go with Digi-Key for the parts you can just use the already done (and great) aussie Group-buy BOM: http://www.head-fi.org/forums/5131615-post1.html

fordgtlover made a great job!

Yep, that BOM ended up working out great for the full config. Though fordgtlover did end up swapping over to resistors from Farnell to save us a little money.

Also, we ended up buying PCM2706 instead of 2707, due to weirdness with the 2707 stock levels. The 2706 is pin compatible and works perfectly in my build.

Just ordered all the parts for a USB+DAC only setup. Hope I don't blow it up since all my previous DIY has been a couple of CMoys

...... well don't edit it out. Tell us what the problem was, and how you fixed it.

Can be very helpful to others that way!

I've been slacking on my y1 parts order, otherwise I'd be able to offer you a comparative review. Soon!
