Have any of you guys used the Eichmann Bullet Plug RCA connectors? What were your experiences with them?

I have been using them for the past week on some interconnects which I made out of some Vampire Wire. I have been impressed with the performance. I compared this interconnect with my Kimber Timbre, a Transparent Link 200, and another Vampire Wire interconnect that I terminated with Vampire Wire banana plugs. So far, the Vampire Wire with Bullet Plugs has been the top performer. A little odd since I made it for about half the price of the Kimber and the Transparent.
