Virtuoso H speaker cable featuring a unique cable structure, which incorporates the best aspects of our renowned SYMMETRICAL COAXIAL and ADVANCED HELIX designs. Six stranded conductor groups of heavy Silver Plated OFHC Copper are compressed and helically twisted around a non-conductive core to comprise the positive conductor group. Two Silver Plated OFHC braid shields with a Foam Polypropylene dielectric between them comprise the negative conductor group. The inner helical positive conductors permit effortless dynamics, a full luscious midrange and sound stage realism. The negative braid shields offer symmetrical electromagnetic control for pinpoint high frequency details, tight controlled bass and other mechanical advantages. The Virtuoso "H" speaker cable is our first cable utilizing the unique "SYMMETRICAL HELIX" design. Virtuoso H has been calibrated to match the widest array of reference speakers. Instruments and voices are precisely placed in your room with a level of realism that will make you shiver during dynamic passages. IBW (internally bi-wireable cable).
