Ok, if you want to see the equipment I have you can go to http://web.randomelectron.com:8089/hometheater.html to make things easier. My question is: Should i upgrade the receiver first or just go ahead and get speakers and get 5.1 sound. Basically my receiver is outdated (5 years old) and is Dolby Digital and not DTS but my dvd player has it. Right now I have polk speakers for mains but I was planning on using them as rears and get better mains and matching center. Which way would you guys go first....new receiver or get new mains and center and move polks in rear so I can have 5.1 sound with outdated receiver? Thanks.
