Python Alpha versus VH Audio AirSine

Given the two cables you mention, i would opt for the Airsine. As a matter of fact, the Airsine is right up there with the Python helix cable. Either choice would be great for you, although I feel the PS Audio ultimate outlet would be a very weak link with such capable power cables.

I'm just not a fan of PS Audio power products. I owned several of their UO and have replaced them with Shunyata Hydras to great effect. Just my opinion though!

It appears Yoby might be confusing the UO with an in-wall duplex outlet...but he is right on the money recommending oyaide.

the hydra is designed for high current loads, did you have an amplifier connected to it? an appropriate supply cable almost doubles the sonic benefit of a hydra. perhaps you could give the hydra another try along with a python helix or airsine?
