Thank you, guys!
Pani, I know you can find Neotech in Sonic Craft and in Parts Connexion; both sell through internet.
I also discovered this weekend that this same Neotech and FIM connector is offered as a Onix connector, avaiable at Parts Connexion for US$ 30,00!
They also offer a silver version of this "Onix" connector but there isn´t any information about its details. I was not able to find anything else on the web.
I didn´t know a Furutech could sound slow, even a bit slow. I´m not looking for that.
My system (Blue Circle+JM Reynaud) seems fast; I don´t want it slowly. In fact, it´s working the way I was looking for with Crystal Cable and Neotech.
I can not say much about the specific difference related to the Neotech connector as I didn´t experience others with the same cable, a Neotech NES-3002.
What I know is that this cable/connector combo brought more speed, detail, clarity without sounding harsh, or analytical. The cable I used to use before was a Blue Circle BC-62.
Cheers,
João
