The Gray series is characterized by solid construction and high quality of workmanship in its price range. It is designed for budget and medium-class hi-fi systems. The cable structure is mainly based on multi-core OFC copper conductors and FEP dielectric. The screen is made of copper braids and aluminum foil. Most of the Gray series cables are terminated with high-quality gold-plated 24-carat gold plugs. In addition, the cables are handcrafted and electrically tested in our laboratory. At the customer’s request, selected cables from the series can be made with an additional anti-interference DFSS or TFSS filter closed by antistatic smart couplers.
