We have a set of (5) AudioQuest Columbia XLR interconnects with dielectric bias system. All cables are custom 16.5". They were traded in as part of a system upgrade. One owner. All cables function. No original packaging. Local pickup or buyer to arrange shipping. We can accept most payment options, $500.00 or best accepted offer.
Fantastically neutral, highly resolving, wonderfully transparent: AudioQuest Columbia interconnects remain a go-to favorite for audiophiles, and for very good reason, not the least of which is the real-world price. To start, Columbia uses AudioQuests's top-grade solid copper conductors – Perfect-Surface Copper+ – and adds an additional layer to the Noise-Dissipation System found in the company's renowned Diamondback and King Cobra models. In addition, Columbia employs AQ's patented Dielectric-Bias System to dramatically lower the noise floor and smooth frequency response. Plus, upgraded connectors (see picture) offering a much more sophisticated and sonically taut design than the competition further enhance musicality. The end result is a spectacular cable that grants music blacker backgrounds, improved nuance and texture, and greater dynamic contrasts. High-end design and performance at a cost that, discounted by 40%, translates to one of the best values Music Direct has ever offered.
State-of-the-Art Build-Quality Nets Sonic Results
AudioQuest Columbia is built around AudioQuest's wonderful PSC+ copper conductors, an ultra-pure copper that has delivers unmatched even-balanced frequency response with speed, detail, and dynamics. Polyethylene tube insulation on all three of the conductors (positive, negative and ground) minimize the interaction between the the conductor and the insulation for greater air and transparency. AudioQuest's proprietary Dialectic-Bias-System keeps noise at bay and dramatically lowers the noise floor of the cable.
Patented Noise-Dissipation System Leads to Incredible Value
The AudioQuest 72V DBS system smooths frequency response and the Cold-Weld connectors eliminate harshness. The three-layer Noise-Dissipation System protects the entire cable from the deleterious effects of airborne noise. Standing on its own, Columbia is a wonderful-sounding cable capable of bringing out the best in any system, but perhaps the most astonishing thing about Columbia is how close it sounds to its big brothers at a fraction of their prices. Maybe it's not so surprising after all. Columbia uses the same conductors as Colorado, the same Noise-Dissipating shielding as Niagara and the same connectors as Sky, and costs a fraction of their prices.
The AudioQuest Legacy
AudioQuest cables are legendary in audiophile circles for their neutrality and resolution. For 28 years, AudioQuesthas worked tirelessly to achieve sonic neutrality in all their cables, regardless of price. Ensuring that music flows unchanged and uncolored requires removing the myriad distortions that occur when a signal flows through a cable. To accomplish this, AudioQuest bypassed conventional cable design and focused their efforts on both the physical properties and sonic characteristics of the conductors and connectors, as well as every other material used in the creation of their cables. This unorthodox approach has led to a number of innovations, the most celebrated of which is the Dielectric Bias System (DBS), a revolutionary and patented system of simultaneously protecting the conductors from outside interference and reducing distortion within the cable.
