I am thinking about doing some upgrading in the new year. I cannot afford a good enough TV to warrant an upgrading that, and I plan to build my own sub. I also am happy with my dvd, so that leaves speakers or receiver. My current set up is Receiver: Kenwood 509 Mains: JBL n28 Center: JBL n-center Surrounds: JBL N26 My budget is going to be around $1000 cnd. My questions is, is it worth it at that budget to upgrade. If so what would make a better improvement, speakers(I am thinking just the mains so it would actually be an upgrade) or receiver. Running 80% ht 20% music. My room is about 20' x 10' x 8'. Anybodies $0.02 is appreciated.
