I ordered 3 Berkline 090s from Ultimate Home Entertainment (
www.rtheaters.com) and they came in yesterday. I am thrilled with them. Good price, good quality, good service. And the motorized recline is great - definitely a must have for the HT.
I have not noticed any blocking of surround sound. However, I usually have my seat reclined far enough that there's no barrier between my ears and the surrounds anyway.
