The Super Flatline was specifically developed as a bi-wire cable with its 16 solid core, Oxygen - Free Copper rectangular conductors. Bass frequencies are isolated on a separate cable to reduce interfrequency interference.

This cable's most obvious trait is its exquisite openess, classical music benefiting greatly. Carrying a well - recorded CD of Messiaen's orchestral music as performed by the Cleavland Orchestra under Pierre Boulez, the Super Flatline showed off a class - leading clarity and detail. Shimmering percussion, airy woodwind and rasping brass all contributed to some highly enjoyable listening. Timpani strokes were fast and clean, and the treble percussion sweet and smooth without sounding veiled. The root of this clarity was the Super Flatline's ability to create real space between orchestral instruments.

With a Dance album (Second Toughest In The Infants by Underworld) the Flatline displayed an adept handling of bass. Isolating the lower frequencies on a separate cable really seems to work, as the drum machine had a new found depth and precision which added pace to the music.The Yank Rock of the Sceaming trees was next in line, and yet again instrumental separation was excellent - bass and drums proved tight and powerful, vocals crystal clear. The acoustic guitars of some tracks were eerily atmospheric, leaving the electric guitars to Rock like crazy. This cable manages to combine both delicacy and clout with clarity and is highly recommended.
