So, wouldnt it make sense to let the AVR do the upscaling like the Denon 1910 with the ABT chip and use a cheaper solution that delivers the A/V through HDMI............
The other factor is what would be the cheaper player? Probably a Pioneer BDP60 with a mod chip to make it universal. What do you think?
A lot depends on what player and AVR you have currently. Yes, if you have a good upscaling AVR, you can use any player with HDMI output and let the DVD output be upscaled by the AVR. If you already have something like the Oppo 983, the BD80 makes tremendous sense as the DVD (and SACD, DVD-A, and Redbook CD) can be played through the 983 and just the BDs through the BD80.
The most important issue will be the capability of the BD player to decode and /or transfer HD Audio well. That, in my opinion, is the critical factor. As long as the player passes BD images without any processing, you will get full 1080P, but, what about the audio?
Though Pioneer and Panasonic make excellent players, they never gave too much importance to audio processing, particularly two channel, in their players. And, for multi channel they always assumed that the AVR audio processing will see them through. Their image processing, though, is excellent.
Because of it's legacy in 980, 983, BD83, Oppo has perfected it's audio circuits for both two channel and multi channel playback. As long as it's maintains the same quality of audio delivery in the BD80, the player will be tough to crack.
The modding cost is common to all players, and should be not be considered as a additional cost for one player. For us in India, we always have to add 100 odd dollars to any player we look at.
