I have been using the DNM Stereo cables and HFTN IC's for sometime now. They replaced Crimson and Audio Consulting Solid Silver and Cryoed speaker wires. Everything that Mapman and Gnobber (cool moniker BTW) has written is spot on. Top to bottom coherence and very articulate bass. Music just flows from these cables as if they weren't even there. DNM has recently developed a speaker cable add-on version of the HFTN. The Speaker HFTN were designed to work with amps that are a feedback design. The science behind them is beyond me, but DNM is not into putting out produts wth out very extensive research. I haven't listened to the Speaker HFTN since my amp is a zero feeback design and not necessary. Contact a dealer and get a description of what they are about and maybe ask them for an in home audition.
Good-luck
