PTFE HAL-O JR.
A weak link in just about any component audio system are the links themselves! Some audiophiles try to overcome this weakness by "hotwiring" their interconnects directly to component circuit boards – and still, high frequency micro-vibrations remain a problem.
Now, there is a solution. HAL-O JR. Damping Instruments fit snuggly over most interconnect plugs to neutralize micro-vibrations. The JR. is a miniature version of the highly acclaimed HAL-O Damping Instrument, and has been proven to effectively reduce microphonic distortion in audio components.
Without the HAL-O JR. Damping Instrument, interconnects act as conveyors, transmitting vibrations from one component to another. Like a child's "telephone" made of tin cans interconnected by a wire or string, vibrations at one end are readily transmitted to the other, and vice versa. In most audio systems, interconnects also encounter airborne vibrations which are passed on to the components to create distortions in capacitors, tubes, digital processors and other sensitive electronics. HAL-O JR. and HAL-O Damping Instruments are also effective for damping capacitors and other sensitive electronic parts directly.
Frequently Asked Questions
HAL-O JR. Damping Instrument
Fits most RCA plugs, 1/4" headphone plugs, coaxial S/PDIF, I2S, DIN, BNC, USB, and fiber optic interconnect plugs, electronic parts, tonearms, and cables approximately 1/2" (11-15mm) in diameter. Available with white PTFE or titanium ring (titanium ring is smaller, lighter, with compact isolation pads; perfect for limited-space applications. PTFE is flexible, allowing lateral installation on tonearms).
Weight – PTFE: 5.65 grams; titanium: 2.12 grams.
white PTFE or titanium:
4 or more: $14.11 ea.
