I have tried Blue Jean cables a few years ago. Over my 50 years pursuing high end audio, I have spent many hundreds of hours evaluating cables and their impact. I have a good system and can pretty quickly characterized the impact of interconnects and other wires in my system.
I own a fairly large collection of very good cables, Straight Wire, Harmonics, Cardas, Transparent (currently on all my equipment), DH Labs, Wire World, Shunyata, and a few more. I found Blue Jeans to be no better than commonly supplied interconnects with components, and cheap aftermarket brands like Belkin, Monster, or common Amazon type wire. As far as I can tell, Blue Jeans managed to sell enough to start thinking about developing something better.
