Which powerchord is best to feed Hydra powerconditioner ?

With the special twist-on connector at the Hydra, the only real option I saw was the Sidewinder cable that came with the Hydra. With most of the power conditioning takeing place in the Hydra, get a good wall outlet (FIM) and make a good connection at the Hydra and you should be in business.

Shunyata has come out with a new powercord for the Hydra called the Python it retails for $1000 and is spectacular.

I have them in stock.

Just recently bought a Hydra and put Whale on it with excellent results.
