a friend of mine has an ebay AK4399-based dac that I might be able to convince him to bring:
its in a case but this was the only ebay pic I could find of the actual board. pretty much a standard 4399 build.
if interest, I can ask my buddy to bring this cased DAC along. I'll have my AMB gamma2 there (wm8741 based) there for comparison.
for my gear, I'm planning to have a custom beta22 and integrated delta1 attenuator. it will be arduino-based, but with something new for this year (if I can get it completed in time!)
