I'm not an electronics. But my friends who are engaged in the manufacture and repair of professional audio equipment is considered these connectors the best for an adequate price. The most important thing - beware of fakes! There are a lot copies of Neutrik connectors made in China and selling around the world. Exactly the same in appearance, but very poor quality of materials and workmanship. I purchase only in Thomann for guaranteed protection against counterfeiting.
All my mics work only with NC3 gold connector from Neutrik and I'm sure that these connectors are definitely the strongest link in my audio chain. Only one remark. I choose these connectors primarily for studio use. For live performances, I would have preferred metal models from Neutrik.
