Kubala-Sosna Persuasion Interconnect Cables

The interconnect is the cable that carries the signal between source, preamp, and amplifier — the most heard cable in the system. Every nuance the rest of the components produce passes through it before it reaches the speakers. A great interconnect does not add character; it gets out of the way. Kubala-Sosna's interconnects are built on the same OptimiZ architecture as the speaker cables, balanced so that the tonal signature of the system stays intact whether the listener is on RCA or XLR. Pair pricing reflects how interconnects are actually used — left and right are matched at the build stage. Lengths from 1m to 3m in half-meter increments cover essentially every reasonable analog run.

Persuasion is the mid-OptimiZ sweet spot. It does not introduce new product types; it executes the existing complement at a higher level. The build is more demanding, the materials more refined. This is where the line stops feeling like a starting point and starts feeling like a destination — listeners often stay here for years. The right customer is the listener with a fully sorted system who knows the cables are doing real work and wants the OptimiZ architecture without crossing into the Fascination price step.

Persuasion as the analog interconnect is the cable for the listener whose preamp and DAC are settled and whose interest now is making the signal between them disappear. Termination is genuinely a buyer decision at this tier — an RCA-terminated Persuasion paired with a single-ended preamp like the Moonriver 404 Reference or an Audio Hungary integrated runs cleaner than the same tier in XLR forced through an unbalanced input; an XLR-terminated Persuasion in a fully balanced chain (a Bricasti M21, an MSB Discrete, into a balanced preamp) keeps the signal where the components were engineered to run it. This is the interconnect to put on a system whose component stack has reached the level where the cable's neutrality is what the room will hear.
