Design critique

[MWP]

Hi all,

Ive just finished my new design for a DAC + Gainclone Amp i planning to build shortly.
Its one of the bigger more complex designs ive attempted from scratch.

Anyone care to give it a once over?
It would be nice to get some comments/thumbs-up from you guys before i put in the many hours designing and building the PCBs for it.

BTW...
Yes, i know there is no volume control besides the two step relay atten. Volume control will be before the DACs.
And, yes, one single ground plane instead of split.

Thanks!

It is.
Try again, looks like the server is a little flakey at the moment.

You did use Protel for that schematics, did you?? I'll post my oppinion after some days, sorry; looks very simmple, but that were your intetnions, were they??
I also consider using digital volume control with 1-2 step relays as one of the best choices with high performance/cost ratio.

In the source... my Linux audio PC.
I will be building 3 of these PCBs and using Brutefir for active xovers.
