Varial XLR Interconnect
Varial XLR Interconnect
Varial-XLR was our first flagship XLR interconnect and was in production from 2001–2011. It featured extremely low conductance and very low susceptibility to RF.
Varial-XLR was introduced in 2001, second generation mark-two in 2002, mark-three was introduced in March 2004. Refinements were made to the cable geometry (better field relations within our ZuB3 model), conductor area increase, metallurgy, as well as shielding and subtle refinements to dielectrics.
Mk.I  The original Varial-XLR is launched.
Mk.II [Q3 2002] Added aluminum shielding to further safeguard signal from RF noise. This change was easy to identify as the observer can see silver glints through the black sheathing. No change in cable geometry.
Mk.III [Q2 2004–2015] Change in cables geometry and resulting impedance. Also, higher conductance copper/tin shielding replaced the coarse aluminum. All versions were able to be ordered with or without the machined V-block which captured left and right cables together to prevent the matched pair from being intermixed.
Ad copy Mk.III
Varial-XLR is our flagship, top of the line balanced interconnect product. Quick features include silver alloy conductors in a multiple conductor exclusively ZuB3 geometry, high conductance on all legs, and high magnitude RF shielding.
ZuB3 is a cable archetype specific to the E&M of the cable. Its not about special materials, chemistry or treatment processes. The technology was invented by Zu in 2001 and allows signal and power to be transmitted with increased immunity from RF while lowering reactance compared to cables of similar conductance and size. ZuB3 design, manufacturing process and correlative electrodynamic relationships are the intellectual property of Zu Audio.
Price is for a matched pair, one left/one right.
Direction of Signal Propagation
Zu Varial interconnects are directional and the V-block points in the direction of signal flow. If V-block was not included in the build, Varial’s label would read in the direction of signal flow.
Varial-XLR, being all Teflon® insulation, will require play before it’s fully burned in, roughly 400 hours. We do not recommend any burn-in devices or special recordings. We do recommend music you enjoy, preferably upbeat full spectrum recordings: rock, roots, full orchestra, big band....

For the possible how and whys about burn-in please see our Answers section.
No maintenance is required for the cable or the XLR-type connectors.
