Over the weekend I had a chance to listen to the v6 with multichannel material.

In prior posts I commented on the large increase in information density vs. the v4 for straight music material (generally Redbook CDs): better imaging, more solidity to piano's, more uncovering of layers of sounds.

Well, multichannel / surrounds benefit too. The surround channels sound more "alive" and there is more detail coming in the surround field. It's a noticeable difference, of a magnitude greater than I'd expected. (And yes, everything was calibrated the same using a calibrated mic, so it's not in any level matching.)
