I have ordered my 1st HT system & the dealer says that I should add a Monster power conditioner. He says that not only will it protect from surges but will also clean up the audio & video. Is this true? I have ordered the Pioneer 45tx, Klipsch rf3, rc3, sb2, ss1 & will soon be ordering a svs sub. I understand that I need a surge protector for the equipment, but am wondering which to purchase.
