Stealth Varidig V16 Standard Digital Cable

Varidig (from 'variable digital') is Stealth's patent-pending digital cable technology. Ordinary RCA connectors are well below 75 ohms, so a conventional cable creates impedance mismatches at each end that reflect part of the signal back and forth along the cable. Varidig shapes its porous Teflon dielectric to be thicker in the middle and thinner at the ends, holding the correct impedance across the whole cable, connectors included. Stealth hears the result as a quieter background, cleaner sound and better focus and attack, with no sonic dependence on length. V16 is the 2016 revision.

This is the standard Varidig V16, without the tuning collar of the V16-T and the selection process of the V16-T Select; otherwise the cables are identical.

Construction

• Varidig principle: porous Teflon dielectric that is thicker in the middle of the cable than at the ends, with conductors that taper towards the terminations
• Holds the correct characteristic impedance across the whole cable including connectors (75 ohms S/PDIF, 110 ohms AES/EBU), greatly reducing signal reflections
• Twisting pitch varies along the length to break up internal resonances
• Dielectric: porous Teflon, dielectric constant about 1.4 versus 2.0-2.2 for solid PTFE
• Hand-made rather than machine-made, so other characteristic impedances can be built on request

Specifications

• Type: digital audio interconnect
• S/PDIF (75 ohms): RCA-RCA, RCA-BNC or BNC-BNC
