I used this app to stream to a 3 year old itouch that has a permanent home docked on a stereo system. This app worked quickly and I can now use my current itouch as a remote and to stream all of my new music to it instead of having to constantly sync the old one. If there is any audio compression over bluetooth, then I do not hear it. Get this amazing app!
