I've pulled out an old Dual 506 turntable to listen to some old and new records. With this turntable, there is a clicking noise that is created when the stylus makes contact with the record (or my finger). The clicking has diminished with time, but is still there. Does anyone know what may cause this? Do I need a new stylus or cartridge?

I have a home theater set up with a Pioneer Elite 45A DVD playes and a Denon 3806 receiver. They are currently connected using a toslink. If I understand correctly what is happening is that the DVD player is sending a digital signal to the receiver and letting the receiver convert it to an analog signal, then sending the analog signal to the speakers. From a pure technical point is it better to let the DVD player convert the signal form digital to analog and send an analog signal to the receiver, or do it as I have it currently set up?

In case some of you were unaware, Music Direct and Audio Advisor have been offering this $350.00 suggested retail system for $149.00!

My roommate and I just bought a nice 65" 1080p TV and need a 5.1 system to go with it. We have a budget of about $1500-$2000. He gets accomodations through his work on Polk and Onkyo, about 50% off on both. So we were thinking along the lines of Polk speakers and an Onkyo receiver. I just have no idea what I'm doing when it comes to power amps/pre-amps. Also, any suggestions on a sub?
I'm new to home audio. I've grown up around live audio and have a recording studio, so I have some idea what I'm doing when it comes to accoustics, but that's about it. Haha.
