The Atlas Ascent audiophile cables arrive in two sizes: These contain 2 sq mm or 3.5 sq mm of the finest stranded Ohno Continuous Cast, non deleting copper within a PTFE dielectric. Use the 2.0 where bass is not a prerequsite or the 3.0 if increased bass is desired. The Ascent cables follow on the Atlas tradition and design philosophy. They offer a holographic image with depth, height and width. They are transparent and an ambience that perhaps was never heard before is given to the listener with the Ascent cables. They offer a silent background, high resolution of low level detail and sibilant free, smear free treble. An AWG equivalence table is available via the link below.
