I am impressed with how user friendly JRiver and JRemote are to use. Switch on the computer which automatically goes into the JRiver program then turn on the IPad click on the JRemote icon then press connect and thats it. Less than a minute and you are up and running. To turn off press the on button on the computer and it hibernates.
Sound quality is much better than my Sonos with no signal drop outs.
I am using usb at the moment for computer/ dac connection but i have a coax sound card from a couple of years ago when i gave up with foobar.
