Hey guys, just want to say really cool site. Learned a lot already. Here's my situation though (and please forgive me if I chose the wrong forum to post in...I chose this cuz they are options on receivers): I currently have a Denon AVR 1603 and am not sure if I am entirely happy with the sound (although it is still decent). I recently had an HK AVR 230 on loan to compare and felt there was a sweeter sound, more defined bass and more umph to the HK. I am thinking though if I were to switch to HK I would want to go to the 330 or 430 for true 7.1 and a few extras since those are becoming more prominent. A couple questions have arisen though that I just don't understand: 1. DAC's: The Denon rep said that apparently Burr Brown DAC's are basically the best and that is what Denon uses (I have recently found out that that is not until their 3800 series though). Is this true that BB is the best? Do you know what other good brands like HK use? Or Marantz or Onkyo? 2. When receivers advertise 32 bit DSP, is that only refering to the sound effect modes like hall, jazz etc, or is that actually referring to the DAC's that decode your movies/cd's etc?? I though for actually decoding music/movies etc 24 bit was the highest? Am i out to lunch? 3. Component video switching: What exactly is the bandwidth of HDTV signals? Am I right in assuming that the bandwidth is different for 720p and 1080i? I noticed that the highest that the HK has is 50Mhz and Denon has 100Mhz. Is 50 MHz adequate for HDTV (720p and 1080i) or do you need something higher like the 100MHz. All this stuff can be a little overwhelming until you can grasp it so any input would be greatly appreciated. I don't don't want to make a hasty decision and buy uninformed and wind up not pleased again. greatly appreciated, Daryl.
