Power conditioner or not?

I concur with the recommendation of the MIT Z-Stabilizer III HG; a fantastic product that to my ears has no detrimental effect on the music and is a stone cold bargain at the pricetag (I have four).

It also critically depends on how clean your power is.

Making such general claims shows a general ignorance of audio (what the heck do x-ray machines have to do with audio?). My system has quality components with quality power supplies with filtration (MX-R, KX-R and Wadia GNSC) and all the components benefit noticeably from power conditioning and power isolation. I guess if each component was over 100K, the size of a small room and took x-rays, my system might not benefit from power conditioning...
