I recently purchased a Rendu w/I2S interface as a replacement for the Bridge in my PerfectWave DAC.
The Bridge had always been somewhat problematic in my system, causing dropouts on high res material. I don't have that much high res, so it wasn't a huge issue until over the last few months I started having similar problems with standard res files - pretty much all files. A tech at PS Audio tried to help me resolve it and some other problems, to no avail. I sold the Bridge for $400 and put that (and another $1100) towards the Rendu w/I2S.
So far, so good. The Rendu worked right out of the box, and unlike the Bridge it consistently shows up on my network. Dropouts are now rare. Replacing my cheapie router should solve the remaining dropout problems. In terms of sound quality the Rendu gives up nothing to the Bridge.
