I had my brother over today (hadn't seen him for a long time) and got to demo the entire system for him. He has his own gear, so he actually appreciates this stuff too lol. So basically my entire system destroys his...3 times I heard "That's a beautiful picture, wish mine looked like that". (I have a 65VT50 with really good settings, he has a Mitsubishi DLP that is giving him problems). And the surrounds and speakers I got compliments too, along with "HOW much did you spend?" (Andrew Jones 5.0 setup FTW!).
And the XV15se...I was able to tell re-running that same scenes as before I changed the amp out that some output is definitely missing from before. But it wasn't to a level where I think anything was fundamentally wrong. I just may need to re run YPAO till I get it to give similar corrections as before and then adjust again the same way (+4 db on the sub). But even as it was, I got comments of "Wow" and "My system doesn't do that!". With the Kung Fu Panda 'Scadoosh' scene, he had no idea that bass was even there!
Always fun to show this stuff off to those who appreciate it
So re setup tomorrow, and then...I don't know. I DO get monster output from about 22 hz up, there is no doubt about that. I still just have no idea if I'm really getting the extension that I wanted, or if I just hear gobs of mid-bass and mistake that for depth. I wish there was a cheap way, without buying a lot of extra gear, that I could have a test and say ok, if you do/play this and you feel something, then you have 18hz extension. (The test tones I used were only 3 seconds long, but I won't do them more that the couple times for fear of hurting the thing.)
