Power Conditioner for your amplifier?


Lately, I've been toying with the idea of trying a power conditioner on my amplifier (ARC VT-100 MkII). I know there has been much written about going straight into the wall with your amp (which is what I am doing currently), but has anyone had any luck with plugging your amplifier into a conditioner? Specifically, I've been thinking of a non-limiting device, such as a PS Audio Ultimate Outlet or a UPC-200.
Has anyone had success using a power conditioner on your amplifier - yes / no? Any thoughts and suggestions will be greatly appreciated. In advance, thanks, and happy listening!

Anyone still using a FURMAN reference 15i or reference 20i power conditioner?

If so, what are the major advantages between the (2) models besides price factor? Keep me posted & Happy Listening!
