You want the best? ... that's what we're using in the studio.
An Equi=tech wall cabinet with all JPS in-wall cable connected to Oyaide R-1 receptacles. Nothing better.. period!

Audience Adept Response R12, AMAZING!!!

Quite the merry-go-round isn't it.
It's is enlightening to know what others are using.
The only way YOU WILL KNOW is Audition some units at home,
on your gear,your room ect.A lot of audio stores will let you audition their products at home.Usually with a small deposit.

They are also pricey.It's YOUR EARS THAT LISTEN,YOU BE THE JUDGE.

Drummertitchell is correct- you need to listen to a power conditioner (or anything else for that matter) before you can decide what is best for your system.

I listened to several line conditioners before deciding on a Synergistic Research PowerCell. In my system the difference between the PowerCell and other well known brands was not even close but that was in my system.

YMMV
