You guys are putting me off changing, I am pretty happy with this Sony amp.
My Dad has a newer Onyko, pretty low spec and my Sony blows it away, mostly noticeable in music.
I know very little about HDMI switching accessories and connectivity adaptors etc. in modern HiFi, but...is there any way you can accomplish your connectivity requirements with a separate HDMI switcher unit and an HDMI --> RGB + optical converter?
. I have a 525 and it's great.
