I did get your PM but was away on a trip all week so didn't have time or opportunity to do much AVS.
I'll check the SC-68 again but you're right the manual doesn't list "Ultra2". But IIRC, didn't THX Cinema morph into U2 on the 09? I'm one of those who don't use THX much, but I'll check both the 09 & 68 again.
But in the end, if your main goal is getting 7 channels on top of DTS-MA, you won't need it
That limitation with the SC-09 (and some other earlier models) is gone with the 68. That was one of the 1st things I checked and I apologize that I didn't remember to post about it in the thread I started
IIRC, there were several posts in the 57 & possibly the 37 threads that said they could add processing but I couldn't check it for myself so didn't blindly accept it
If you recall, there was some confusion back in the 09/07/05 days, some said they could add matrixing some couldn't. We thought the specific player might be a factor with that duplicating rears thing.
I confirmed the SC-68 can add PLIIx & NeoX on top of 5.1 DTS-MA tracks > 7.1 sound. I did this using both the Pioneer BDP-09 player (which duplicated the rears) and the Oppo 93. It also worked with both player PCM decodes & bitstream. My guess is there's probably more processing power in the 68 than was in the 09 era.
But if you want THX for other reasons, I can understand your concern. Because you can add standard matrix processing now, it's possible they decided Ultra 2 was now redundant and that THX Cinema on top of PLIIx would take care of people who like the THX sound. I'll try to find out from Pioneer in the next few weeks, preferably from Walkamo Edited by ss9001 - 8/18/12 at 4:27am
