I thought I would share a setup I am using that has given me the best Squeeze, Jplay integration and sound. K50 and Chord mscaler/tt2.
K50 set to MPD player and Minimserver, Squeeze server running as well.
K50 output set to digital and optical output to mscaler/tt2.
Squeeze server - add UPNP bridge plugin.
Ipad runs Jplay and Material.
Now select the K50 upnp output in Jplay or the Sonicorbiter upnp player in Material.
Note - optical out is my preference for the mscaler. You can use any. This is limited to 192k. For my PGGB files I use direct stream to an EX and usb into the tt2.
