Ultra high purity, 6N (99.99997%) copper. Advanced refining process still leaves great variations in composition of impurities and crystalline structure. All 6N copper materials are different, and in reality, most of the so called 6N,7N materials are not measured comprehensively. As shown in our analysis table, ACROLINK is the sole producer of stabilized ultra pure copper. It is essential to maintain high purity to achieve extended frequency response because composition of impurity inhibits capability due to impedance variance. After formation of actual cable core structure, a unique stress-free process is applied for maximum effect, in a special environment maintaining original purity to restore crystalline disorder caused by extrusion process.

Japan Made. Highest manufacturing standard Contents .. 2x 6N-A2030II RCA or XLR Interconnect Cable Single Retail box removed. The cable comes in an over 2kg wooden box which will increase postage by quite a lot. If you want it, after you sent order, we will reply with amended postage, or post using a slower cheaper option. Supplied by Authorized Resellers in Japan with standard manufacturer's warranty.

The new polymer polyolefin, presently the best insulation material available, has been chosen for extremely low dielectric constant factor which is 1/3 of polypropylene and 1/4 of PVC.

The RCA plugs are made by Sanpo Shindo with their patented Ecological Brass which does not contain Lead, instead contains silicon. There is virtually no resonance due to its high damping characteristics to realize remarkably clear and fast sound with high resolution and minimum contact noise level. It is precision machined and finished with high quality 24k gold plating.

Balanced 2-core co-axial cable is the fundamental structure of higher quality audio cable,. It provides equal environment for both poles to enable ideal balanced transmission. ACROLINK sets up an ideal spacing between conductors for optimum result.

Resonance absorption is one of big factor that decides the final sound quality. ACROLINK always pays extra attention and built up tremendous know-how. Every product is carefully composed with selected materials in order to achieve perfectly balanced and effective absorption.

The structure of cable must be designed ideally for optimum electromagnetic formation, therefore with minimum adverse properties such as electrostatic capacitance, inductance, dielectric constant factor etc.
