Both are excellent phono cartridges but are quite different. I currently own a Benz Lp cartridge and have for several years and am very happy with it. I do not own the dynavector but have heard it and it to is a fine performer. The Benz lp is rich sounding with great full body mid and low bass. The LP is dynamic and fat but has a great musical presence and is exceptional with vocal material. The only fault of the Benz line is that they do not have the detail and speed of there Japanese or German counterparts But with the passage of time I have come to realize that extracting the last bit of detail is not everything and to me balance is more important in enjoying the musical experience. The Dynavector had more speed and detail compared to the Benz Lp and also has a faster tempo in general so some people might prefer this quality over the fatter body and somewhat slower Benz Lp. I could live with either cartridge as both are top notch products so it comes down to personal taste if you want more speed and detail (Dynavector) or a fatter and very rich sound with full body bass (Benz). Take you pick and enjoy.
