some audiophiles will tell you that they can actually hear an audible difference in fidelity with their a/v gear plugged into a line conditioner, typically high end stuff like monster ht. i have helped a buddy calibrate his h/t. he had an sacd player. and had a triplite line conditioner. out of mere curiosity, i honestly tried to hear a difference using the line conditioner and then bypassing it all together. i could hear no discernible difference. i personally think it is a foolish way to blow $300 - $600. well, that is if you want one that is actually "high quality".
i'm a huge advocate of using a ups to protect your investment, but i'm in the category that think line conditioners are bogus. now you say that on a hard core audiophile forum and they try to rip your head off. however, based on my experience they are superfluous.
a quality ups is already taking care of your gear. my ups' 2-3 millisecond switch over to battery during a power failure. kicking in during brown-outs (100 volt range) and kickiing in during spikes (140 volt range). and the battery and circuitry inside the ups itself makes for an excellent filter. it will output 120v/60Hz almost until it dies, if a/c power is not restored. and miine also have built in filters for my phone and ethernet.
also, many high end receivers have spike resistant circuitry or breakers.
my 2 cents.....
p.s. - if people don't understand the need to have your expensive a/v gear behind a ups, take the test leads on your dvm and shove them into a socket. watch it for a couple of hours, especially on really hot days when everyone on your grid is running their air conditioners. it'll surprise you how much the voltage fluctuates. i've seen it go from 112v - 128v at my house. that kind of vacillation in electrical pressure will fatigue sensitive electronics plugged directly into a wall. and people are always concerned about spikes, but many don't realize that a sustained brown-out will fry your system just the same.
it was not a problem to bring money to his house at 10pm.so why is it a problem to call and bitch.it wasnt a problem when we were all sitting around smoking pot together.yes i said it we all were smoking pot together.what now stupid.
