I don't have DPL ll and don't feel too left out using original DPL. Probably nice to have but this is the digital age in which 5/6.1 etc dominate. VHS fans and standard TV watchers will probably make good use of DPL(3?)
DP II X, I have read, is very similar to Neo 6 in sounding, so that is why I asked in the first place. I know its not the same, but reportedly close anyway. I just hate to buy a receiver now, only to regret not having the DPIIX. I wish these guys would make upgrading possible. At least it would be there if one wanted to upgrade. All well. I'm not convinced yet that not having DPIIx is a deal breaker. Doesnt sound like many others are worried about it either.
Denon widescreen is one of Denon's DSP, similar to H/K's Logic 7.
PLIIx has just been unveiled, and it will take time before it starts making it into receivers. I wouldn't worry about it now, there are lots of other options on the 3803. There will always be new sound formats, so you could wait forever. And being the PLIIx is an analog based format, I don't think it is very important. Now if HD-DVD decides to use a different format, then I might wait. . .
