My current setup is as follows...
Samsung 42" HD LCD
Onkyo TX705 receiver
Mains: Polk Monitor 70's
Center: Polk CS2
Surrounds: Polk OWM3's
Subs (2) Velodyne VRP 1000 and VRP 1200
Here is my question. Aside from the surge protector, I don't own a power conditioner and not really sure I understand how they will make my system sound better. Also, watching movies my HT is louder than I'll ever need it but...is there a way of improving the clarity? Would an amp help? I've put this HT system together over time and I'm not interested in changing speakers of subs (although if I ever did I'd go to RTi's and SVS sub) so all I want to know is a way to improve my current setup. Thanks!!
