All Dream V10 cords are made of multiple bundles of 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 four types of Dream V10 AC cords:
The four types of Dream V10 cords are similar, but NOT THE SAME: they have the same AC carrying multipath *** (multiple groups of wires, STEALTH proprietary configuration), but the ground layout and ground filtering is type-specific, and thus each Dream V10 AC cord has its type printed on its carbon shell, plus all four types are individually color-coded to avoid confusion.
Dream V10 Preamp (black with blue stripes) - for preamplifiers
Dream V10 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)
Dream V10 Power (black with FIVE silver stripes) - for analog power amplifiers, turntable motors
Dream V10 Wall (black with TWO silver stripes) - for AC power conditioners and AC power strips
It is proven possible and advantageous to use any Dream or Dream V10 cord (any version) as a "stand alone" cord in any place**** in a system, mix and match Dream cords with other cords: some listeners 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 STEALTH 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 V10 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 V10 AC cords as designed - i.e. as a system, and not as a stand alone AC cord.
