Another company you may want to check out is Furman Sound . They also are known in the Pro Audio/Video field. One thing I like about their surge suppressors and line conditioners is they use series mode protection like the brickwall units. This is a superior surge suppression technology compared to the MOV's used in most consumer devices.
One thing you should be aware of in the Tripp-Lite isobar line conditioners is "Neutral to ground bonding at the secondary eliminates common mode noise and provides an isolated ground reference for sensitive equipment". In some, but not all cases when I used these they actually exacerbated ground loop problems. As always YMMV, etc., etc., etc.
