PS Audio AV5000 vs Audience adept Response aR6

I currently owns the AV5000 and was thinking of trying out the Audience power conditioner. Price wise, is almost double the PS Audio for the used market. Has anyone had the chance to compare these two power conditioner? Should I get the Audience or stay with PS Audio AV5000? Please share your comments or inputs here. I would hear your 2 cents.
Thanks!!
