Yes. There is another company that makes a similar product, however it costs MORE! See Widescreen Review's site for an article that reviews all the major line conditioning products. You might try the PowerCompany products. They can provide similar benefits in some systems. To you PSskeptics. The PSAudio line is very much a YMMV product. The benefit you notice depends on your system's ability to resolve detail. The higher end the system, the greater the percieved improvement. It also depends on the quailty of the power in your area. When you get into true high end (which seems to start at around $15K...) the difference is well worth the $1K price tag.
