I'm just starting to learn about this area myself, so take my suggestions with a grain of salt. I just bought a Touch because of the very reasonable price and it was a breeze getting it up and running with my home network. Note that its highest sample rate is 24 bit 96 khz, not 192khz, so it won't utilize the full capability of your BDA-1. I don't know of any threads about mods to the Touch (can you refer me to those?).
I have not compared sound quality of all of the outputs on the Touch, but it does have optical and coax digitals outs which would give you other connectivity to your BDA-1 than USB.
So far, the Touch seems a real bargain. For $234 you could try one out and, if you don't care for it, they sell pretty well on Gon. Good luck.
