Power conditioner for Wadia

Over the last several years, I've owned several power conditioners (PS Audio P300, Richard Gray 400S, Chang, the original Shunyata Hydra, Shunyata Guardian, etc.) and have had mixed results. So far, none have taken my system up to that next elusive level.

I have a Wadia 861 that I use with a Kimber Palladian PK10, which made for the kind of difference I'm seeking again. The power conditioner would be used for just the Wadia -- so I don't need a big unit capable of handling many components and hundreds of watts. I'm intrigued by the smaller Audio Magic units but wanted to hear first hand from people who may have already gone through this. I'm also looking to spend less than $800 new or used. Any suggestions?

Thanks. -- Ron
