Re: Onkyo-TX SR-800 Rcvr.,old Polk spkrs.Which should I upgrade 1st?
The most important component in an audio system is the speakers. Problem is picking them. There are more variations with speakers as far as sound reproduction goes than receivers, so selecting a receiver would be an easier task, imo. If it were me I would start with the speakers, but take you time to be sure you are indeed improving the system over your current setup.
Some home theater dealers will allow you to audition speakers in your home. They usually get a bit more for this service though.
