Hello I joined the site earier this week and am now seeking advice. I'm thinking about upgrading our stereo AV Reciever. The one we're using now is a Sony STR DE875,a 5.1 reciever I believe rated at 100 watts per channel. Sounds pretty good using Mirage tower M-790 fronts, and Mirage M-290 rears. Our tv is a Toshiba 36" that still has a great picture and the wife wants to keep it till it starts to go bad before we invest in lets say a 50-52" plasma/LCD wide screen in the future. So my question is would buying another reciever now looking to the future be a good idea? And do you think Buying Pioneer, Onkyo, Denon, or Yamaha will improve in the quality of the sound comming out of the speakers we have? Thanks, Will
