Michael, i have had very good performance from both the Jena Labs Fundamental one and the Evolution Acoustics power cords.
both have in-line conditioners that both quiet the circut and provide a filter than eliminates back feed of noise back into your circut.....which is significant. they both truely isolate each piece of gear.
i used the original Hydra for awhile......the Jena's were quite a bit better with a lower noise floor and blacker blacks.
another thing i have found even more significant than power cords is the Oyaide RS-1 duplex outlets and outlet covers.......which actually are more significant than the power cords......as crazy as that sounds.....
good luck.
