Best AC line conditioning devices?

Tried the Mapleshade unit primarily due to good results with their isolation products. The AC conditioner would seem to be too cheap and mundane looking to do much good, but was pleasantly surprised with the results in my highest-end system. It's a keeper!

The Shunyata Triton has put to shame all contenders in my system including the SR MKIII and Bybee Stealth.

I like Furutech because they don't change the sound of your system too much.

after using PS Audio, Furutech, Isoclean I settled on HB Cable design....the best and the most natural(means no artefacts or limits for all system).

Prcinka, which HB product are you using? If one of their power strips, are you using any of their power cords or signal cables?
