A.S.P. POSEIDON POWER CABLE: TRITON, KRAKEN, LEVIATHAN are names of mythical denizens of the deep. POSEIDON, the ruling deity of all the seas, stands above them all.

More than just another high-end audio power cable, a statement, a showpiece, the culmination of 25 years of development, experimentation, and user feedback.

Combining a multitude of exclusive technologies and design elements intended to extract every last bit of possible performance.

If a single word encapsulated POSEIDON’s most prominent attribute, it would be “control”, low frequency in particular.

POSEIDON takes imaging and staging to the most extreme level, exposing layers of depth and uncovering every micro and macro detail while maintaining complete control across the entire frequency range.

A large and heavy cable, with layers of impenetrable shielding and mechanical damping not found on any other cable design.

A literal black hole for interference and noise, making POSEIDON the quietest power cable on the market.

Made entirely by hand with our own proprietary components and absolutely no “off-the-shelf” commercially available parts.

Unique, game-changing design and technology whose effects are indescribable and must be experienced to be appreciated.




“Stage III Concepts specializes in power cables. It makes sense a specialist would introduce the next major design innovation: a power cord with a vacuum dielectric. What a difference the Poseidon makes! It has wondrous timbral beauty; at the same time, it delivers thunderous low-end. ” MARSHALL NACK, POSITIVE FEEDBACK (read in full here).


“I’m still being transported into a new and different sound world, but just not the way I was with the Poseidon. I was simply stunned with some of what I heard with the Poseidon. My jaw dropped. What I am trying to say is that with the Poseidon, it is almost impossible to do anything but focus solely on the music. It literally draws you into the world of the recording.” – CONSTANTINE SOO, DAGOGO.COM (read in full here).
