I am not sure what source you use for SBT, and I love my SBT and have an upgraded power supply for it, but I can't imagine why one would take a source and drag it through another device? The interface on the SBT is great (in my opinion much better than the BDP-1), but I look at it as a poor man's BDP-1 overall. As soon as I get around (whenever that is) to digitize more things, I will look at upgrading the SBT. The BDP-1 can do internet radio and music files and if I had one, I probably would be putting the SBT in a secondary system. Are you contemplating just running digital music files through it? And if so, then why not straight through the BDP-1? I guess I am trying to figure out the purpose of why the SBT needs to be in the chain.
