y1 gamma-1 DAC

Anybody notice that MisterX and AMB are working on a portable DAC with USB, optical and coax support over on Headwize? The portable optical DAC is something a lot of people have been asking for, especially in a form factor equal to a mini3.

Cool, that was only posted 6 days ago. Definitely sounds like it would be much higher quality than the AlienDAC. Wonder how much it would cost for the BOM?

There's not even a schematic yet so it's a bit premature to compare it to anything or to be guessing at home much it'll cost to build.

It does sound like an interesting little project although I suspect a lot of SMD work which I'm not all that fond of. I see a new work source in my future...

Read the top of the thread. AMB is talking through hole except for the chips.

It looks like it will fill in the space between PCM2702 DACs and Twisted Pear's stuff. $50 or $500+...where's the middle? This could be it.

Fair enough, but the DAC chip being used is higher quality than the PCM2702 used in the Alien, right? As long as it's well implemented, which is probably a pretty safe assumption, it should be a good step ahead, but of course it will probably be a step ahead cost-wise also.

I'm keeping my eyes open for both the new BantamDAC and this one.

Ah, I missed that on first read. Lovely!

amb's post came the morning after I cursed all the 0805 SMD stuff on the AlienDAC. The 1206 inductors - easy, the 0805 capacitors had me cursing.

Wow, this is exciting! Sounds like a perfect companion for the Mini3 + EEE PC I've been using at work to stream audio from my home server.

Looks like I'll be watching [yet another AMB project] with great interest. My poor wallet .

is it possible to add the metronome ASRC module from twisted pear to build a nice upsampling home DAC?

Later in the thread AMB says he wants to design a high end DAC with that capability too (not necessarily from twisted pear):

Fun times ahead...

The higher end one surely looks nice, but probably over my budget

I suspect this would be a possible, but unsupported feature. However, it will only work in a USB-only configuration.
