Manufacturer's Description:
The Ultra high performance Dream AC power cords are very thick (approximately 35mm= 1.38 inches in diameter), but flexible.
All Dream cords are made of multiple bundles of shielded silver-plated OFC copper in Teflon insulation, in our proprietary "distributed LITZ" configuration - which puts the least stress on the wires and provides the least possible electrical and electromagnetic interaction between the wires than any other configuration or geometry known to us. Each wire bundle is enclosed in a separate hermetically sealed STEALTH para-vacuum tube** (equivalent to 15-fold vacuum). The combination of para-vacuum and distributed LITZ reduces all forms of interaction between the wire bundles even further, plus - due to an extremely low effective dielectric constant - assures very low energy storage, which is subjectively perceived as improved clarity and very fast coherent sound.
There are three types of Dream AC cords:
Dream Preamp (black with blue stripes) - for preamplifiers and AC power conditioners.
Dream Power (black with silver stripes) - for analog power amplifiers, turntable motors
Dream Digital (black with gold stripes) - for digital gear (CD players and transports, digital processors and AD and DA converters, digital and class-D power amplifiers)
The three types of Dream cods are similar: they have the same AC carrying multipath *** (multiple groups of shielded distributed LITZ wires), but NOT THE SAME: the ground layout and ground filtering is type-specific, and the three types of Dream AC cords are marked and color-coded accordingly.
It is proven possible and advantageous to use any Dream cord (any version) as a "stand alone" cord in any place**** in a system, mix and match the Dream with other cords: some beta testers have done that and reported excellent results, but in order to take the full advantage of the design, the entire system must be powered with Dream cords.
A full complement of Dream AC cords offers virtual star grounding* of the entire audio system via using AC cords.
Using the correct Dream cord types for all components in a system allows achieving star ground layout (single point ground); When you mix and match different AC cords, you have more than one path to the ground, and therefore there is a ground loop (or several ground loops). In addition, most other cords have ground path which is not RF transparent enough to realistically dump the electromagnetic pollution to the ground. Still in addition, most other power cords are unfiltered, and when used with digital equipment, these unfiltered cords allow the noise from switching power supplies in the digital equipment enter the analog components' circuitry through their straight ground path and thus compromise perceived clarity of the sound.
This is a theory, and it's based on our own "model" of how things work. Some people would disagree (there is always someone who disagrees with any theory). But in order to accept - or challenge the theory and ultimately hear the improved sound, we highly recommend that you evaluate the Dream AC cords as designed - i.e. as a system, and not as a stand alone AC cord.
