So, after messing with Sound Settings I've found that Straight sounds the best. I was watching the Matrix on HBO HD last night and it sounded like crap. It was on Standard and I had to turn the Volume up to -10dB. I'm sure most of it was the movie but the bass/sub was so boomy I couldn't take it. Sub was calibrated at -10dB by YPAO and the volume is at half. I turned the channel and watched the last thirty minutes of Spartacus: War, or something to that effect and I was amazed at how it sounded. Really good surround effects with all the swords clinking and clanking in the background and to the side. The overall sound was great too. I turned the volume down to -16dB and it was plenty loud. It was still on Standard. I then switched it to Straight and it sounded even better.
The last two weeks it's been on either Standard or Adventure for Directv content. I've watched Prometheus, the Campaign, the Matrix, Shameless, and various other titles with it on those DSP Settings and it sounded like crap on all of the movies. I couldn't hear much without turning it up and it didn't sound "clean" at all. Well, last night, after switching to Straight, I tested those same movies and there were no issues and it actually sounded like I had intended it to sound when I bought this system. I did however, keep the Enhancer on. I'm not sure what it's doing exactly but it sounds better with it on. It says it's Compressed Music Enhancer in the manual.
Also, does the -10dB on the Sub's Trim Level sound correct? I think it goes from -10 to +10dB. Crossover was calibrated at 80Hz but I changed it to 90Hz.
