OK, just got the Denon DVD-1600 DVD player, mainly for DVD-Audio. I currently have an old Yamaha HTR-5240 receiver (stop laughing). Anyway, the question is: does the DAC in the receiver have any bearing on the DVD-Audio signal coming through the external 5.1 inputs, or is the player in control of that signal? What is boils down to is, should I get a receiver with a 96/24 DAC, or a receiver with a 192/24 DAC? And if I get a receiver with a 96/24, will I be able to listen to DVD-A 192/24 stereo tracks? Just for giggles, I'm looking at the Yamaha HTR-5660, but if anyone has a better idea for a receiver that pumps good DVD-Audio, and is in the general price range (give or take $150), let me know too. One more thing, frequency range is the best indicator of proper speakers for DVD-Audio, correct? And if so, what frequency range should all of my speakers fall into to get the best audio possible? My L/R Fronts are 35Hz to 27kHz, rears are 80Hz to 30kHz, and the center is 70Hz to 30kHz. Is a speaker upgrade in the cards also? Thanks for reading this muck, and if you answered, double thanks.
