"How 'bout from the conditiner to the unit??" Would depend what kind of unit you're talking about. Here's an excerpt from an email I sent someone last night who was asking my opinion of a particular PC:
I use a variety of PCs based on their cost/performance attributes in certain locations in my system. The three products I'm using are:
Aural Thrills (3) Silver Big One for it's high energy transfer (10 AWG conductor size) but where I'm not terribly concerned about it picking up RFI, or broadcasting it (I wouldn't use it with digital gear for instance, because it's not shielded.) In my system, it is used to power two Martin Logan CLS IIz electrostats and a Martin Logan Depth subwoofer. These are applications that call for quick power response (energy transfer) but would not benefit from certain fancier attributes such as shielding and/or mechanical shock resistance.
Audio Metallurgy (3) Gold 9 14 AWG gold alloy cord which I use to power two Mark Levinson outboard power supplies for phono preamp and preamp. The power supplies basically require minimal current so the smaller conductors are OK. A third cord powers the TT, tuner, and cassette deck. They are not shielded. Main advantage is stable and faithful current delivery (gold alloy) with equipment that is on 24/7. As with all cords for my source equipment, the power comes from a balanced power unit, so shielding is not really necessary since any noise would be self cancelling.
Purist Audio Design Venustas on my CDT and DAC. !O AWG shielded. DACs and CDPs or CDTs seem to benefit from cords that have big conductors. Nobody has explained why -- they're not high current devices. Shielding is always necessary with any kind of digital equipment (even using balanced power) to keep the equipment from broadcasting RFI into the air, It's also good to have the digital equipment plugged into a filtered outlet on your power conditioner, or if you're not using one, than a separate wall circuit to prevent digital hash from getting into other equipment thru the AC supply.
Purist Audio Design Dominus for main amp. Best energy transfer, best shielding and mechanical shock resistance, most expensive. Allows the amp to be all it can be. And I use a second one for the Exactpower regenerator.
