That's my experience as well Erik and Dean. Mostly depends on the source material. On the Live at Radio City (Dave M and Tim R) Blu-Ray I did a comparison of the new HD track and the 'standard' surround track. Switching back and forth through the audio menu of my PS3 I did prefer the HD format as the soundstage was just 'bigger' - seemed to extend beyond the walls of my HT. But then again this was not a blind level matched comparison so YMMV.

Cheers,
