I have tried tons of cables over the years with 801s3. But none better than Bass Euphoria (sold through www.jeffssoundvalues.com) for bass driver and Harmonic Tech Pro 11+ for the mids-highs. You will not believe the bass extension, articulation, and speed after burning in for about 48 hours. Substantially better than my former Kimber Monocle XLs. Otherwise I use Magnan Vi balanced interconnects.
