Best power conditioner?

First you must determine if you need a power conditioner.

"For me" it's Tara Labs Power Screen AD-10B... I believe it was originally designed by EAD, though. I had Tice Elite, too... very good!!

In my sound system I tested a lot of similar equipments and mostly of them sounded with less dynamics. The only ones that truly gave sound benefits in all parameters (including the dynamics) were the Shunyata Hydra 8 and the Burmester 948. I personally prefer the Burmester 948 because It has a perfect synergy with my system and sound a little more natural.

Very best regards,

easily the most difficult issue for me to address in my system has been both power conditioner and cords. i was about ready to give up completely on conditioners until i listened to the acoustic revive rtp ultimate. unlike anything i have ever heard and the only one i have experienced that does not cause problems. i love this device so much i am ordering some other products from acoustic revive to try and it's stuff i would have never considered before. their designs and philosophies are quite different from what you typically see in this industry but i have a feeling we are going to hear much more about them in the near future.

And the only way to know for sure if you are getting benefit is to put the conditioner in, do some critical listening and then remove the unit and listen again. If your immediate response is that the overall presentation is improved by its presence, then you have your answer. If not, keep looking.

The only units that have ever made a difference I could clearly hear and that I enjoyed are PS Audio's regenerators, the Premier being the most enjoyable of these.
