Gotten my Acrux just recently, and have totally different perceptions.
The built quality of the cable is good, they were nicely braided and terminations seems strong. As for cable breaking, u need lots of good care for such after market cables, I've bought whiplash cables before and for aftermarket cables, have to be very careful not to bend cables too much.
As for memory effects, I have experienced close to none, but I have to say the cable isn't as flexible as my Unique Melody default cables, but hey, the thickness is different. The cable were a good upgrade, it sweetens the mids, expands soundstage, tighten the bass but ever so brighter in sound signature. I pair it with my UM Mentor and i'm hearing good stuff. At those prices for pure silver cables, its really hard to find elsewhere.
