My experience with Sony ES labeled products has been pleasant. My current HT system consists of a Sony TA-E9000ES pre/pro, Sony TA-N9000ES amp, Sony TA-N80ES amp, Sony TA-P9000ES multi-channel preamp, Sony DVP-S9000ES DVD/SACD player, and Sony ST-SA50ES tuner.
Sony ES is legend. Go to the Agoraquest Forum to get information about Sony ES receivers. Folks there may have actual experience with the receiver you are considering.
