Bought an officially refurbished S770H and it was like new, packed well and all accessories, ran audessey eq and it did improve. only have a 5. 1 speaker setup in small room but works very well, love the tunein radio, and controls well via roku smart tv. Obviously sound is dependent on speakers but seems nice and smooth w/ no harshness in all modes.

The AVR-S770H that was sent when purchased did not work. After 2 calls with tech support it was determined we needed to send it back and wait for new one to replace.
