Returned the receiver, 鶹 was unable to provide a replacement/exchange . Generally Sound is as expected - very good , the the new Digital Cinema Auto Calibration IX and 360 Spatial Sound Mapping shine. Issue is with the HW quality, at start-up randomly the receiver would make a loud clunk/thud sound , I have seen reports of the same issues on other forums, maybe a faulty relay. Also once the receiver froze not responding to the remote or the the power button, has to hard-power off. Sony Support was not helpful.
