As much as I liked the sound besides the distortion and the other problems, I didn't get a new pair since I didn't like the neumann costumer support. For now I moved on, maybe I'll get a pair of genelec, barefoot or idk what other, still choosing. I don't know if to trust neumann. I will see.Pc can be a major noise source, but I've ruled that out as a possible cause by hearing the same noise when the PCs off.
That's a bummer, did you try a replacement set? Or did you move on entirely?
