These were originally 8TC and 4TC two pairs I bought from Audio Advisor. I sent them to Kimber to be combined into 12TC for my new non-biwirable speakers. I also upgraded to WBT angled, locking bananas. Total cost was around $350.00. Receipt will be included as proof. Cables are in mint condition and sound very dynamic, spacious, and smooth. Shipping will be USPS Priority. Selling price includes paypal and shipping within USA only. Will ship internationally at whatever Post office charges to final destination. Price is strictly firm. Thanks for your viewing.
