My experience so far: I bought a PS Audio Direct Stream DAC/ Streamer with the the Bridge !! ethernet adapter about a month ago. In short the DAC is great but the Bridge II card left a lot to be desired. The music was dull and flat. All but the really well engineered recordings were a drag to listen to. Just disappointing. Plus it kept dropping the internet signal.
In my frustration I called PS Audio for tech support and was persuaded to try the AirLens Streamer. It arrived yesterday (10/23) Night and day. I was amazed. It was money well spent. The card is pretty simple vs. the AirLens which is a good bit bigger, heavier, and has multiple connections.
Conclusion: Buy an expensive streamer. You won't remember the price after a while and the joy of all that music out there at your fingertips is exhilarating.
