With the little info you gave. I would start with the speakers. The thing to rember with speakers you get what you pay for. Great speakers are not cheap. Next do away with the chzzey reciever.
Best place to start when upgrading?
Right now my tastes are watching DVD's and occasionally listening to about all types of music. Now I have a 3year old Technics Home Theater receiver, Sony DVPS-530 DVD player, Technics EQ, and a Sony 27" Trinitron. My front speakers Kenwood are about 15 years old 8" woofer and a 1.5 to 2 inch tweeter, a JBL passive sub, and a Technics set of rear surrounds and center channel. I want to upgrade, but I don't know where to start exactly. I need some pointers, general ideas, brands to stay away from, brands to favor. Any help will be welcomed. Thanks
