So nearly all of what you just said is beyond me. I must confess, I'm a novice. I'm just getting into it really. I'll explain where I'm coming from: The 2200 AT speakers my dad had for years, and bought me a new set that was on sale on Amazon for around $650 dollars(including sub). A complete 5.1 system, 2200 AT speakers, with a BIC PL-200 as the sub. I then bought two more surround AT 2200 speakers, and then read a bunch of reviews and got the Marantz SR6007 for a deal as well. So I was pretty ecstatic because these speakers were 2500 dollars back then! And the new model of them is 2500 dollars. I mention the prices because I'm not sure how equal my components are. I'm looking to upgrade, and trying to figure out what the best thing to upgrade would be first with my budget. And my CC distortion concerned me.
So anyway, what I started doing, was experimenting with players, because I felt that I wasn't getting the quality of sound that I thought I should be getting.
So the PS3 was my first player for DVD's and Blu-rays. Then I decided to try an older Pioneer Elite DVD player my dad had, and to my amazement, it sounded better on some DVD's.
That led me to think a player was extremely important. Then I found the Oppo, which people RAVE about, ranging from the actual disc transport to the DAC's.
So I'm really just learning by myself. There's no HT stores around, so the internet has been all I've had. All that led me to the conclusion that using the DAC's in the player would make a significant difference, and I'll be honest, when I first got it, I was disappointed. It was so underwhelming compared to Audyssey's immersive sound. But I was like, "nah, must be how you've set something up.. that can't be right", so I fiddled and fiddled, to where we are now, where the DAC's sound wayyyyy better than they used to, but there's still pluses and minuses to either using my receiver with Audyssey or the Oppo and its DAC's.
To answer your questions,
1) I calibrated with my own ears. Just based soley on what I liked. I've spent hours and hours tweaking it, listening to different content from different sources.
2) Calibration stats:
Concert DVD's: CC -10db FR -7.5db SR 0db SBR 0db Sub 0db(up 15db on my Marantz)
Music: CC -7.5db FR -7.5db SR 0db SBR 0db Sub 0db(up 15db on Marantz)
Movies: CC -10db FR -4db SR 0db SBR 0db Sub 0db(up 10db on Marantz)
Distance: CC 8.75ft FR 8ft SR 4ft SBR 5ft Sub 9ft
3) Yes, I'm referring to listening to Multi-Channel music and 2ch music. And btw, actually the Oppo does have DTS Neo, and sound his coming from the CC.
4) Sub is a BIC Acoustech PL-200
5) And yes, my crossover actually used to be 80hz, which in my AT manual it says 80-100hz is recommended, but I've found that 120hz sounds better.
6) And I was confused of the bass stuff you were talking about with the Oppo and all. I don't know what all of that means.
Another thing I will say, I watched Pacific Rim last night, and I felt things performed pretty well except the distortion I noticed in the CC. I've actually been looking to upgrade my subwoofer because while listening to music, concert DVD music that is, it doesn't seem to have enough oomph in it. But during the movie it had AMPLE amounts of bass! And it doesn't seem to struggle with CD's either. So maybe the Oppo bass stuff is playing into that? I don't know if that's relevant, but it was peculiar to me. I also tried my dad's AT 422SB that he bought with his 2200 speakers, and it actually did worse on the concert DVD's. This btw, was with using the Oppo's analog outputs, again to which there are pluses and minuses, as they seem to bring out the weakness in my subs but yet can sound way more accurate bass wise, but I have no reference point, just my personal taste so I could be way wrong. You seem to know a lot more than I do.
^^I know that's a lot of info, I appreciate anyone who takes the time to read that and help!
