Sony 7.2 Channel Home Theater 4K AV Receiver (STRDH770) Amazon.com: Sony 7.2 Channel Home Theater 4K AV Receiver (STRDH770): Home Audio & Theater

I just bought the STR HD550, the step below it, but now this one is on sale at best buy, so Im gonna try and swap them. Do yall think this will he a major improvement over my DH550? Im using it mainly with my turntable and CDs. Thanks

 

A major improvement ? Probably not.

 

Looks like the only difference is 7.1 vs 5.1 hook up so save your money if you are not doing 7.1 surround sound.
