I've got the AVR20 . It powers my entire system and results in totally noise-free ("black") backgrounds.
Enabled me to get rid of all the expensive Shunyata and Furutech power cables I had as they don't have any effect whatsoever downstream of the TorusPower unit - in that sense I can say that not only is it worth every single cent but also resulted in some savings :-) The only boutique power cable I now have is between the wall outlet and the AVR20.
My place also sees abnormally high voltages during day time hours so the AVR option was a no-brainer for me.
