It was a demo cartridge of Anthony Prutton of Central Audio UK. Following his information, it has less than 20 hours, so I continue breaking it in. I changed the VTF to 2.15gr, and result is slightly better. Off course, we are very severe here, this is an excellent cartridge, but if I compare to my Ortofon SPU, S15, MC20MkII, DL103, Linn/Supex Troika, the sound of the Dynavector is a bit flat, thin, no depth, imaging could be better. Off course, this is a combo LP12/ARO/DV20x2 on an AN OTO SE Phono signature tubed phono stage. This combo can not reach the soundstage, imaging and involvement of my 301/3012/Troika combo.
