Not many of these examples circulating in the world - the HELIX series is the second to last step in the current HFC strata. Like the PRO series above it, it implements a point-to-point array of strong spherical magnets within its waveguide.
I have been methodically removing all of the common electrical conductors from my system and upgrading them with magnetic conductors. This conductor performed flawlessly and is now fully "run in" with about 10 months of continuous use between Server and DAC.
I am the original proud owner selling this unit so that I can upgrade further to the next level Pro series.
I'll entertain any questions and am also providing a generous BUY IT NOW option.
My community feedback, communication, service and packing prowess is legend.
I'll pack and ship it within the US/Canada flawlessly with full photo documentation for your peace-of-mind. PayPal fee of 3% is expected if necessary.
