Best power conditioner?

I had a Shunyata Hydra 6 with 20amp Python power cord and recently changed to the Audience Adept with audience cords. They sound different and I can see where on initial impression the Audience may be more impressive. After several weeks of listening however I can only say that they are different. The Audience my have a little edge on detail and dynamics, the hydra an advantage on air, sound stage and natural timber. Both sound good and I would be happy with both. It is my understanding that many recording studios use the Shunyata hydra products and in my experience it makes sense as for me it was the most neutral of the two.
