I own both of these, although the dynavector is the low output version. Phono stage is a Rhea. The Dynavector is very dynamic, and somewhat technicolor (e.g. brighter, bolder and more contrast than real life). The Shure is more of a precision instrument, but compared to my Shelter 501-II, it lacks the "breath of life." Bass is solid, and overall it seems very balanced, if less exciting to listen to than the DV. I like the Shure with closely miked jazz and chamber music, but prefer the DV when playing large-scale orchestral stuff with "Sturm und Drang" The Shure tends to be bright and detailed, but not harsh. One of my good buddies has a jico stylus for his Shure and it sounds a lot nicer than mine with the stock Vxmr stylus.
Overall, if I had to pick only one, it would be the Dynavector, which plays in a different class than the Shure. Both are nice in different ways. Pick your poison?
HTH!
