Do you all use power/line conditioners in your home theater setups? If so, what would be a reasonable way to go? I am putting together a respectable, not audiophile-ish, system: Onkyo TX-SR606 AV receiver, Emotiva XPA-3 amp, RTI A9 fronts, CSi A6 center, FXi A6 rear surrounds, and DSW PRO 500 subwoofer. To be honest, my only experience with ANY kind of power conditioner is in computer use, and passing by them in Best Buy and thinking, "There's a sucker born every minute." However, I'm thinking there's something out there that's worth the money and will improve the sound. If there is, I think I'm asking the right people. Thanks, and Happy 2009!
