Summary: Original unit was destroyed by lightning - all the accessories survived in great shape. This unit is installed as a direct replacement - and for much less than the original cost. All the connectors and wiring matched right up. I used the paring instructions in the manual to connect to the rear-room wireless amp and it was done!
Summary: This system is very good for the price. But we used it to replace a Bose 3-2-1 Series II system, and we're missing the Bose sound quality -- not a fair comparison, I realize. The surround speakers, in particular, just don't have enough umph to make the sound as present as we'd hoped. And audiophiles won't be impressed, I'm sure. Probably most annoying was our discovery that the surround speakers are not, in fact, wireless.
Summary: System sounds great; however, if one would like to extend a speaker further out into a room or place it on a wall... forget it. It appears the Sony AV speaker connectors are unique to the AV package deals. No company sells the unique connectors. If one of 6 connectors break or if planning to upgrade or extend the wire beyond the 15 foot range... forget it. It has been one frustration after another. I've contacted Sony and several independent electronics stores.
