You will definitely need a new receiver to handle all of the wonderful sound options that are available today - too many actually.

Last year I snagged a Denon AVR from BB Canada on line - it was the last one on clearance with a list price of $800 that I got for $450. Bargains can be found if you watch & wait.

I've never owned a Denon before & after I figured it all out, I am really happy with it. These beasts, regardless of brand, are really quite complicated these days, so expect a learning curve & some frustration, ha! Lots of assistance can be found here though.

Funk Waves has a great reputation as well. I believe that they are on the Sunshine Coast - a misnomer at this time of the year...
