These cables are made with the idea that cheaper cables should never annoy, nor should they sound too rolled off and hide details. They are simply very well-rounded.
Made with silver plated hollow banana plugs that fit perfectly into speaker and amplifier terminals alike. Seriously, they've got just the right amount of resistance. I really like them, not just for their sound characteristics, but also for their handling and usability.
They're constructed with 4mm² (12 AWG) tinned copper in XLPO. It's stiff, but it sounds good.
That's about it.
