"tube based power supply for Active Shielding"

Well thats a new one for me. I've seen the cables in Stereophile that use a bias voltage to supposedly cut down on noise, but one based on tubes?

More audiophool rubbish

That one doesn't even appear to have the plate cap active.

Good grief.

Incredible but not suprising. Yet another well hyped toy for filthy rich audiophool lawyers and doctors to pee away their money on.

Umm, not that uncommon to use some high voltage gas thyratrons as rectifiers, and in that case the grid is used as the plate and the plate cap is left unconnected. A pair is usually used with FWCT... Not sure if this is what they are doing or not. FWIW this works quite well at a couple of hundred mA and a KV or two... Hope I am not giving anything away..

I suspect this gizmo will do as much for sound quality as myrtlewood speaker cable stands...

I totally dig their product photography, though... :-)

Bootstrapped shield most probably. I used such a trick in a long cable snake to connect guitars directly to the mixing console.

Isn't biasing an interconnect more or less the same idea as biasing crossover capacitors ?

Interesting to see that the 323A's top cap isn't even connected to anything.

Sorry for going off-topic, but isn't it funny to imagine what Apple Inc.'s lawyers will do once they see the Synergistic Research web page layout? I'm pretty tempted to let Apple know

The first sentence of the article explains exactly what the thing is:

"Sculpted as a work of industrial art..."
