Mrmarbach has a very good point, often not mentioned by the hi-fi press. You need a killer system for the extra fidelity of Hi-Def audio to really show it's hand. At the level of the �400 amps and �1200 speaker systems, you may as well stick with DD and DTS, straight off DVDs as you won't have the system to resolve the increased fidelity, even if you can decode it. That's my experience of Bluray audio. The visual difference is much more apparent, much more easily.
