Do they really make a difference? In comparison to other surge protectors, where do these stand for HT? Any thoughts would be appreciated.

If you do a little searching in the forums, I think you will find all the information you need.

FWIW the term "power conditioner" implies that the device will somehow improve AC power quality, IOW deviations from a pure sine wave. This is quite different than a surge protective device which simply protects connected equipment against one type of power quality issue: surges. Most consumer power conditioners have filters intended to reduce noise on the AC line. They will generally have some form of surge protection as well. And some will have automatic voltage regulation as well.

The question you have to answer for yourself is: will any improvement in the quality of the AC provided by a power conditioner improve the performance of you audio or video gear? Many who seem to be in the know here think not, at least with typical CE power conditioners. Others think so.

As far as surge protection, power conditioners are going to have pretty much the same kind of MOV-based or series type surge protection as you can buy in a surge protective device for somewhere between a few dollars (MOV-based) and a couple hundred dollars (series type).

I have a TrippLite LCR2400. It is both a "power conditioner" and a stabilizer. It can correct low or high voltage, saving your gear from a brownout or overvoltage, and has a circuit breaker to protect you from a surge. They're about $250 on Amazon (less if you can find one on ebay / used) and definitely worth the money as an insurance policy. Mine is in the bottom of my full-size AV rack and feeds everything in the system including the LCD TV in the other room (via a remote power bridge system).

Furman power conditioners / distributors are handy to help filter out RF and give you a simple means of turning components on / off as a group, but not models stabilize / correct line voltage unless they specifically say they do in their specifications (e.g., AR1215 or AR117).

My rack *also* contains a Furman power conditioner toward to the top, to provide a handy means of switching power to just the network and VOIP components, and to provide illumination for the whole rack. You'd be surprised at how often I need to bounce the network just to clear clogged routing tables or reset the cable modem (arrgh... Comcast... get it together please). But that's another post for another day... smile.gif

A circuit breaker cannot protect against a surge. Brownouts do not damage AV gear. Your AV gear is so poorly built that it needs external filters to prevent RFI on the AC line from affecting its performance?
