Actually:
the first test film was the same in 7.1 DTS and as you already notice the first weaken. the higher tones sometimes sounded like in a hall, but is also evident in a 2.1 system.
By contrast, 5.1 movies there are then no longer so much to complain about, just fine!
What I like is the television standard, much better than the bleak tone of my TV)
In addition, I have my cell phone on my Sony the right app downge. and now all about mobile operated (whom you want)
CONCLUSION: it is worth the for New !!!!
