Hi, I'm LounginLiz. I'm new to forums. I need help in understanding home theater systems. Are HDMI ports necessary for good quality sound? I will be using this system in a small living room. I have an old Technics system from the early 80's(?). I plan on getting an HD LCD tv soon, but thought I would buy my surround system first so I can space out my money output, if you know what I mean. I would like to stay around $300.00. Can anyone give me some good advice on which system would be good for me?
