Does the Rio Receiver produce additional gappage between tracks? That is, if my music is encoded so that it doesn't gap on, say, my empeg, will it gap on the Receiver?

I want to add that with the AudioTron, the digital out isn't always sending a valid SPDIF signal to the receiver. So, if for some reason there is a large gap between the end of one track and the beginning of another, your stereo may not respond well. My Sony STR-DB1070 is quite good at handling this issue. Once it gets a valid signal it almost immediately starts making sound.

Be aware that this situation does not always occur. AudioTron many times seemlessly goes from one track to the next.
