The Atlas Hyper cables offer unbeatable value. Unheard of is a PTFE dielectric and 6N pure (99.9999%) OFC conductors at the prices of these cables. Indeed the Hyper is almost certainly one of the finest Hi Fi performance bargains today. The Hyper cables arrive in sizes of 1.5sq mm, 2.0 sq mm, 3.0 sq mm and Bi Wire. Choose the 1.25 where bass isn't a priority or for rear speakers in a 5.1 system for example. Choose the Hyper 2.0 or 3.0 for increased bass and the Bi Wire for improved high frequency information in a bi wire speaker system. The Atlas Hyper cables share many similarities with the more advanced Ascent models. The Hyper cables are smooth and refined allowing for continuous listening over a prolonged period without causing listener fatigue. An AWG equivalence table is provided below.
