Hi Joey, When I posted my last message, the sound restitution of my cables were extremely warm.
They had approximately 200 hours, and then extreme warmth left and in this moment with approximately 260-280 hours they are rather neutral.
I will still await one can with the case or they would still evolve.
I think of buying Quattro soon if there is a new model evolved with a look like PowerCell.
Do you have information on the replacement of Quattro soon?
Thanks,
Jazz
