Hey Dekay,
The cable ends maleability is just right, atleast for me. I can shape it to fit different equipments' posts and it stays in shape.
Like you, at first I wasn't familiar with Bogdan cables. I emailed and asked whether he offers a trial period. He replied no and guaranteed that I will like them. He didn't even ask what equipment I have. Well, I still wanted to try the cables out...
I am not sure if ground connections are vital to the sound, but I whole-heartedly think you should give Bogdan cables a try. Partially because you can tell me which cable is better, OTA or Bogdan. But, mainly, I think Bogdan cables are great in my personal system. So, if you wanna buy a sub $100 cable, might as well get Bogdan. I can't think of a better alternative.
