Hi all, first post. my HK 630 has died

and i need something to replace it. im looking to spend between 3 to 500, it can be new, used refurbished... as long as it runs

. my big question is this.. im more interested in sound quality than anytyhing else. feature wise, my only needs are 3 hdmi in's (no upscaling is necessary, everything is already 1080p from the source) 7.1 or 5.1 with preouts. Should i be looking at older, more hi end gear or newer, lower end gear? and will all these auto set up features really make that big of a difference in sound, rather than breaking out the RS sound meter and doing it myself? Thanks!
