Awesome! Are you going to sell short kits or complete kits? I'm most interested in just the boards and case, I have 2/3s of the parts laying around.

The boards and case would most likely always be sold separately.

Excellent, thanks! I really can't wait, it looks like an amazing product, which is no surprise, you and cobaltmute tend always impress.

scootsit, you've been excited from the beginning.  I will make certain that you get an opportunity at a kit/case.  If for some unbelievable reason that doesn't happen, I'll send you one of my prototypes.

Is there a BOM available? I may have some free time this weekend, and I'd like to see what I have in my parts drawer and what I still need.

See if this works -

Note that for the kits, there are equivalent RCA jacks at Mouser that I used, but the 3.5mm jack is only at DigiKey.  You may also need some help from cobaltmute on X1 - it's gone to 1000 part minimum orders at Mouser and DigiKey.

I have the cases back from the anodizer today.  Laser-etching begins Monday.  Mouser has shipped me the kit parts, but I haven't received them yet.  In any event, the kits should be available soon.

It works. cobaltmute, any ideas on X1?

Regarding the RCAs, is there room to panel mount them?

I assume your kit includes X1, maybe that is the best way to go...

For PCM2707, you have it speced with PCM2707PJTRG4, is there any difference between that and PCM2707PJT or PCM2707PJTG4?

He will have to answer this one ... if nothing else, we may be purchasing them in qtys of 1000, because they're used on the grubDAC, too.

I don't think so - things are very tight and the PCB + case are designed for the PCB-mounted RCA jacks.

Yep - we have them for the first 100, anyway.

 

For PCM2707, you have it speced with PCM2707PJTRG4, is there any difference between that and PCM2707PJT or PCM2707PJTG4?

It doesn't matter - any PCM2707 or PCM2706, for that matter ...

Tomb, you're a gentleman and a scholar. Sample request sent to TI, going to go through my parts drawer tomorrow!

The C3391 in 12Mhz is an equivlant part from Crystek that is on order at Mouser.

It looks like the follow should also work from Mouser.
695-CSX750FBC-12
815-ASV-12-EJ-T

As I type this, there is 4500 is stock between those two parts so you should be good.

Great, thanks!

Some shots of the cases prior to laser-etching next week:

Looks great Tom!! Thanks as always for putting so much time and effort into projects for the DIY community. 

I agree, that looks sexy, particularly without the bezels. I'm not sure it even needs engraving, there's something so simple about it.

Can the outputs of the DAC be hooked up to two different devices at the same time? I'm considering feeding this into two amps.

Also, what are the dimensions on the speced RCAs and 3.5mm jacks, I want to try to find equivalents at Mouser.

Thanks!
