AudioQuest Columbia .75m (2.4 ft.) Pair RCA to RCA Interconnect 2 pairs For Sale


Length (Feet) 2.4

Length (Meters) .75


SOLID PSC+ COPPER: Perfect-Surface Technology applied to extreme-purity copper eliminates irritation and provides tremendous clarity.


DIELECTRIC-BIAS SYSTEM (DBS, US Pat #7,126,055): All insulation slows down the signal on the conductor inside. When insulation is un-biased, it slows down parts of the signal differently, a big problem for very time sensitive multi-octave audio.


AudioQuest’s DBS creates a strong stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS pack’s batteries will last for years. A test button and LED allow for the occasional battery check.


PE AIR-TUBES: Air is a nearly perfect dielectric. Once the DBS is attached (for 2 weeks), the normal irritation caused by un-biased FEP is eliminated.





Originally purchased one and one half pairs (1 pair and a single IC). Some time later, I changed my system and ordered another single to make two pairs. The newer IC purchased direct from AudioQuest, consistent with manufacturer’s changes, shipped with 72V DBS instead of the 48V DBS which the other pair and one half shipped with.



Condition excellent. Original Packaging.



$325. Per pair, as is, including free shipping if within 48 contiguous States of America.

Please PM if interested.


Best, Richard
