Hey Guru,

Alright.....The Yamaha 670 is a great system.

However, I have heard the Harman/Kardon system; and it is truly amazing. A good friend of mine has one and I go over to his house every friday after school and watch a movie over there. They are an amazing setup.

I'm also a teenager (so...you know we aren't very quiet with surround sound Wink Whenever we "crank" music; it doesn't distort with that system either. You may spend a bit more with Harman/Kardon, but, you REALLY get your money's worth.

He's had that system since it came out, and it still sounds as good today as it did when it first came out.
I would highly recommend it.
