Opus, Coupling, and Neo:6, Channel coupling seems to agitate Neo:6 multiband steering. Options

I routinely use DTS Neo:6 to listen to music. I was listening to Amy Grant's "Oh How the Years Go By" track and noticed severe artifacts in the surround channels. Pro Logic II exhibited similar results, although not nearly as noticeable. When I listened to the same track with coupling disabled, the artifacts were far less severe for Neo:6 and similar for Pro Logic II.

The bitrate used was 128 Kbps and the encoder was opus-tools-0.1.5 with libopus-1.0.1.
