amb: where do you get your boards done? Also, what's with the strip on the top and bottom, to ground the extruded case to the board?

I use Imagineering. Not the cheapest fab, but I am happy with their quality and service. I understand that Justin at Headamp also uses Imagineering, and we know he is also a fanatic when it comes to quality.

Yes. This is similar to what I did on the Mini³ board, except this time I have them on the top and bottom sides of the board, with a row of vias tying them together.

Now I just need to tap the digital output from my portable mp3 player, and my portable stack will be awesome!

Just to briefly add to this point, I have used other board fab houses and Imagineering is the best that I've come across.

The only other boards that I've gotten in the last while were my Pimeta and some I ordered through BatchPCB (who uses Gold Phoenix).

The gamma1 prototype board is very nice. The soldermask on my BatchPCB ones were uneven. From recollection since it has been a couple of months, the Pimeta was nice as well. I'd not hazard a guess about the Pimeta versus the gamma1 as one was HASL and the other ROHS silver plated so the shiny-ness makes a difference in perception.

I just checked Imagineering's advertised specials. Only minorly more expensive than Gold Phoenix.

I think I know where my order is going to go for the board I'm developing.

A couple of dumb questions if you guys don't mind..

1. Does USB work on any OS? including Linux?
2. Does USB output bit perfect?
3. How is the jitter performance in USB->S/PDIF converter variant?
