I was looking for a plugin to close the gap between ITunes and the CD. I have ripped my CDs in lossless WAV format. I then send them from the Macbook through Apple TV to a Benchmark DAC and into my tube Cary preamp and Audio Research tube amp. However, the same CD played in the Marantz CD player compared to the ITunes showed ITunes to not have as much resolution or depth of soundstage. Your plugin as narrowed this gap to be negligible. Furthermore, it works with Apple TV and the remote ap on my IPhone.
For a profile, I am using the using the built in speakers telling the system that I have a MacBook Pro 15" unibody.
