I was thinking about DVD-Audio today, and a few things arose in my mind: 1) With the dynamic properties of such hi-res. recordings, how can one use a surround receiver's amps only and enjoy a DVD-A recording? Tell me that adding a separate amp is the only way to truly enjoy DVD-A (and any other hi-resolution audio for that matter, eg. Dolby D). 2) How much more dynamic is a 2-channel and multi-channel DVD-A track than a regular DD or DTS track? 3) How bout I open up a can of worms at HTF today? The whole point of this thread is for me to have a reason to suggest to my freind that he ought to add a separate amp to his Denon in order to enjoy DVD-A on his future RP91. I know the arguement that adding separate amps for home theater is still being debated, but for DVD-A (and SACD), isn't this issue even more important? Discuss.
