I'm getting ready to start the new build, but wanted to pop back in with some thoughts. I have been listening a lot to the sentinels over the last few days and they rally are fantastic! I sitll don't have an optimal area, but was able to set them up as good as good be expected in the temp area that I do have to work with. I am still swappin between the cv5k for 2 channel and stereo on movies, and using the Oultaw (somebody buy this thing!) for running l/c/r for movies at times. Obviously they seem to open up a bit more and really get going with the CV5k, but with just the 200w/ch on the Outlaw, they still sound fantastic. I am now getting a feel for the midbass that Andrew kept referring to as well. The wife and I watched Superbad and Miami Vice today. Superbad is mostly dialgue, and they handled it with class. Miami Vice was great too...there were times when Colin Farrel's voice was very "present" in the room. very impressive. Once my daughter got home, I watched Ice Age Continental drift with her and they were great with the effects.
I can't say enough how well these things perform in general, nevermind for $400 a piece. Matt did such a great job with these that I have roped him into helping with my mega build, a victim of his own success
