Quartet of terminals Mundorf Mconnect of 8mm for use in bicableado. They have been developed to meet the most demanding demands, Mundorf offers these models made of oxygen-free copper, plated in 24 carat gold. The copper terminals are turned from a piece of copper OFC. The advantage of copper over brass, which is commonly used for cost reasons and easier to be machined, lies in its atomic structure: brass has a resonance frequency of 22khz, which is very close to the audible zone, and Which can be perceived as an unpleasant sound to metal. The copper terminals are much more difficult to produce, they do not present this resonance and their sound is much more pleasant and natural. They are delivered mounted on a Mconnect Tpac150 board. The price is for a pair of terminals mounted on a plate.
