Best AC line conditioning devices?

Thanks Ken. I understand Wadia p/s is very good. I'd be interested to hear the difference a Sound Application unit would make system.
Any chance you can audition?

I have heard the SR power cell, and their limited production unit, top of the line R. Grey, PS Audio, and many others. I neglected to mention the Plasmatron can be plugged into your high current conditioning/surge protected outlet. One of the best improvements I heard was the Plasmatron plugged into a top of the line Richard Grey system with 220 V etc. Just stunning what that level of treatment does to not letting AC influence the sound. Recordings suddenly had an a loss of edginess, and recordings were more individual sounding. The sound of the different recording venues were vivid. As mentioned before, worth a listen....and no, I don't work for VH Audio, and I had to pay hard currency as well for mine. One friend did return his unit....only to upgrade to a bigger one. What did it for me was how much video improves with one. Really interesting....... PT

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.
