my av receiver (Denon AVR 2801) dates back to 2000 and I think it's time to upgrade. The rest of my system currently comprises Mission speakers (773e floor standing sides, 77c1 centre speaker, and 77ds rears currently no subwoofer), Sony BDP S760 blu ray player and Sony KDL EX503 TV.
Obviously this technology has come on a lot in 13 years and aside from the obvious feature advances (net connectivity, video up scaling) will the difference in sound quality (now adding a subwoofer) be particularly noticeable and significant. I appreciate this may seem a silly question, and that sound quality can be a subjective thing, but I wouldn't want to spend the money and not see a significant difference.
I will keep my Mission speakers but would be looking to replace the receiver with either the Denon AVR X2000, Onkyo TX NR626 or Yamaha RX V575 and add a Wharfdale Powercube SP10 subwoofer. My listening room is not ideal for a 7:1 set up but I would like to future proof myself with that capability.
Grateful for any advice/opinions.
