I'm using JRiver and a Microsoft Home Server with the Bridge and tagNplay with my iphone. The server is connected to my the cable companies DSL Router via CAT5 cable, than a separate CAT 5 cable runs from the DSL Router to the Bridge in the PWD. I've really been very pleased with the results. The PS Audio and JRiver software seems to work very well together with an occasional need to reboot the DAC or tagNplay. I still haven't tried PS Audio's eLyric as it is not ready to be used for Microsoft Home Server. I hope to add the ipad 2 when it becomes available instead of my iphone for tagNplay. I think the larger display will really make this a killer system to use.
I really am amazed at how well it all works together, even though the system is still in its infancy. And the sound quality easily rivals the PWT/PWD combo. Usually I can't even tell the difference between the two. It would be interesting to get together with a couple of friends to do a double blind test between the Bridge and PWT. If you like the sound of the PWD DAC, (most do, some don't) this digital system is one of the best sounding most fun systems to listen with I've found.
The biggest chore has been ripping all my CDs to the hard drive. But this has been fun too, it is amazing all the great sounding music I'd forgotten I have that have just been sitting on the shelf!
Well time to start ripping CDs, I think I'm on number 999. . .
