By the way, thanks for all of your contributions, in reading this thread, some things became apparent on my part. A) I did most of my posts at work between calls and things vying for my time. As I tried to figure out at work what was going on at home, and in my car, I forgot some things, and realize I blamed the P7 for being warm sounding when the issue was my car.
The car tweeters are located in the corners of the dash, just below the windshield. As one can understand, the dash and windshield form a kind of megaphone that directs the highs into the cabin in kind of a compressed fashion that will affect the sound. So when I noticed that my car system played certain tracks with more highs present, that was most likely the reason why.
Then the tweeters frequency response is most likely higher than typical home speakers as the car environment is noisy and pretty bad for sound reproduction. So after reconsidering, I realize that I was blaming my home system, and P7, for something it had nothing to do with.
I was actually thinking of selling it, trying to chase that last 3 or 4 percent of sonic bliss. Gosh, that would have been a mistake.
