What customers say
Audiophiles consistently praise the Cardas CCRR S Binding Posts as a reference grade upgrade. The core theme is superior sonic performance, with users noting enhanced clarity, better dynamics, and a more expansive soundstage. This acoustic gain is attributed to the proprietary construction featuring nonmagnetic copper and specialized plating, which maximizes signal purity. Reviewers also highlight the exceptional build quality, confirming the robust feel and precision engineering. While the investment is significant, enthusiasts consider these posts a crucial, long term component for unlocking high fidelity system potential. The positive impact on the listening experience overwhelmingly justifies the premium cost, cementing their reputation for acoustic integrity and durability.
Know before you buy
The long post design is specifically engineered for speaker cabinets with thicker walls. It provides the extra clearance needed to ensure a secure, stable connection when standard-length binding posts are too short to mount properly.
Silver is used for its exceptional electrical conductivity, while the rhodium flash provides a hard, non-oxidizing surface. This combination ensures the connection remains clean and conductive over many years of use without the tarnishing often associated with bare silver.
Yes, they are designed to fit the industry-standard 3/4-inch center-to-center spacing. This makes them a direct drop-in replacement for many high-end speaker cabinets and crossover plates.
These posts utilize glass-filled nylon, a material chosen for its high mechanical strength and excellent dielectric properties. It ensures the binding posts remain rigid and electrically isolated from the chassis, even under the tension of heavy speaker cables.
Each set includes two binding posts, the dual insulator plate, and the necessary mounting hardware. You will have all the components required to outfit one speaker terminal pair.
