I currently have a Pioneer 506 XDE of which I have had 4 great years of service. I also have a Panasonic BD30 and a Denon 2809 with Sky HD and 4 B&W 603,s with a B&W Centre and a B&W Sub. with £2000 burning a hole in my pocket shall I either upgrade to a Pioneer LX5090 with its native 1080p or should I keep my old 506 and upgrade my amp to the gorgeous Pioneer SCLX81 and matching Pioneer BDPLX08 blu ray player. Any suggestions would be appreciated.
