I don't know what causes this kind of sound but it shouldn't be like that for sure.
I'll just mention Goldring 1042 as well because that's what I have for my Nottingham Spacedeck/Spacearm. I used to use Acoustech phono stage but now use VAC Avatar's SE phono. This is not a warm cartridge, it is on the warmer side of the range. To my ear it sounds balanced and just right. Of course, one can do significantly better even with the same set-up but at much higher cost. I once wanted to replace it with Nagaoka MP500 but changed my mind, I just see no good reason to replace it.
