No, I have not, but thanks for the suggestion, it is also on my list. The BDP-1 with BDA-1 DAC combo retails for $4300, in the same ballpark.
I keep reading that the Sooloos interface is one the best available. I do like the idea of a one box solution that is plug and play reliable, but Sound Quality is very important. It seems that many of these other interfaces are works in progress (read some of the posts at the PS Audio forum re problems with the bridge card, NAS interfaces, twonky, tagnplay, elryic etc). I am not sure I want to be an audio interface beta tester. Seems like Sooloos has already worked through many issues. Maybe the iPad app could be better though.
