Im always hesitant to recommend products because of considerations we all realize (system synergy, room, likes/dislikes, etc, etc.) But here goes...
Im just burning in a pair of Harmonix 101 SLC and after only 50+ hours they sound amazing. I believe they need close to 200 hrs for full burn-in. Im using them with a Wadia 861 (GNS Upgrade), direct to an Accustic Arts Amp II-AC and Silverline La Folias.
My praises of these cables so far are: they make the background much quieter allowing for more music to flow through. They extend the width and depth of the sounstage. They have great frequency extension on both ends and a very life-like midrange. Good luck.
