Summary: My first SONY I still have and it's 20 years old (STR-D2070). Still works perfect but I wanted new technology. I went for the 5000ES and can say I'm beyond impressed. I have pushed it to the limit over the past couple years and it has never failed.
Summary: I am running Cerwin Vega VE15F speakers with this and it sounds amazing. I have been to concerts that are not as loud! It also is a 7.1 channel system, not 5.1 as displayed here (has outputs for both surround back speakers.) Pros: Fairly simple to set up and get going.
Summary: Theres a reason this is a this is a $ 1500 unit. I can't elp but to be impressed by the unreal sound quality of this receiver. This is from a guy who has a Mark Levinson system for music. I know music. This receiver blew my mind.
