SOLD..
The description is from Transparent website. These worked really well with my speakers, but I have upgraded to Siltech DC jumpers.
The following is from manufacturer's website:
These biwire adapters are a significant upgrade over the flat, stamped metal plates usually provided with biwire speakers to bridge the 2 sets of + and – binding posts. The many heavy, tightly twisted, high purity copper strands in Transparent Reference or XL Biwire Adapters have superior current carrying capability and transfer more musical details and wider dynamic range than biwire speaker plates.
