Don't be penny-wise and pound-foolish
About a year ago, our power company had a voltage spike that took out appliances and electronics in several homes in our neighborhood. We lost several electrical devices, including 2 badly blackened (scarily blackened) brand X surge suppressors, a garage door opener and 8 GFI outlets. Our desktop PC, office printer, and monitor were protected by a Tripplite surge protector and were undamaged (although the Tripplite unit's surge circuit was rendered inoperative#. After this incident, I improved our surge protection with 3 Tripplite surge protectors. This included an ISOBAR8ULTRA on my audiophile sound system and a second on my HD TV and surround sound system. These surge suppressors are top quality. For audiophiles, each of the 4 outlet pairs are electrically isolated, improving the power supply separation of individual components. While these are a bit expensive, the confidence I have in Tripplite (quality and long business history) along with the high replacement cost of my electronics make the price paid for an ISOBAR8ULTRA insignificant.
