I currently have a Sony DA2400ES, which I've had for 4 years, in a 7.1 set up with B&W CM/CM1 centre and front speakers, 4 X B&W M1 as surround and back and ASW608 subwoofer. Sony BDP-S480 Blu-ray and Sony KDL40W4000 TV. I'm thinking of changing the receiver for the Sony STR-DN1040 which gets really good reviews but on looking at the spec for the two receivers, I'm not too sure if this will give me much of an upgrade in sound. I don't plan to upgrade TV to 4K in the near future, until price drops but wondered if anyone had any advice on whether the receiver change would give me any great benefits?
All advice welcome.
