Because of bad quality of cable plug it was blocked in a socket of expensive sound card, I was forced to use help of special service company to carefully dismantle it from card. Visually it looks similar to Neutrik plugs, but in reality it is very diferent, in the place where Neutrik has embossing, Thomann branded plug has a hole which is a reason of blocking. I refer to Thomann, but didn't get real service, still cable is unused.
