Can anyone who has built one compare the sound to another dac?

ruZZ.il has spoken favorably of the Gamma's SQ, but does not mention names.
Shouldn't be much longer until we see some side by side comparisons.

Side by side, the black one sounds a little darker, while the silver one sounds more 'metal'

ruZZ.il, me, and another friend had a little meeting a couple of weeks ago. We compared the y1 to DAC Ah (with mods) and to a balanced Opus. All of them worked with a B22 (balanced) on K701 (balanced).

The result were quite surprising as the y1 was unbelievably similar to the Opus, there were a few minor differences, but I dont think there was a definitive winner between the two.
In fact we were so pleasantly surprised that for such a low sum of money and in such a small case you get sch a high sound quality, that me and a few other friend have decided to build one for each of us, so now we are just waiting for the parts to arrive and than we'll have 4 more y1

I can't wait to see what Ti will be able to do once he gets going with that high-end DAC he's been talking about. If the y1 at this price and size is such a great DAC, than I guess we're all in for a treat

Great looking Gamma's Robb.

^Thanks for the encouraging word KT. I really look forward to whatever Ti's got in the pipe.

Did you use two Gamma's to feed the balanced Beta?

no, the B22 used a SE input and the conversion to balanced was done internally.

OK thanks KT.

I meant to add that I cannot imagine how much time and effort it took MisterX and Ti to design this little DAC, and no doubt much more for the future projects, not to mention making all the pcb's and part's made available to us all, with mucho help and guidance on these forums.

Thanks KT88

I'm just waiting for MisterX to start selling these. I have no DIY skills

I think i took off the Pin1 U1D solder pad.
But looking from the schematic, U1D Pin1 is not in use.
Can I just leave it?

It is unused, just make sure the solder pad is either off and out of the way, or out of the way..

Just finished my y1 DAC and have encountered a problem.

When going through the initial test guide on amb's site, it fails at the 3.3v to ground with VCC and Vbus jumpered with a usb lead plugged into a computer.

I get ~ 4.95 volts instead of 3.3v.

How do i find out which component is faulty?

Check to make sure there no solder bridges on either U1U (pins 2 and 3) or U2U (pins 1 and 2).

Both are reading much more then 20 k ohms so i assume bridges arn't the problem.

Anything else i could try?
