Have I missed something here...surely the manufacturer suggestions are just that..... suggestions. The actual settings will depend on a variety of factors; I have six switchable loadings on my Step-up, and my Koetsu sounds at its best on different settings with different music. I rather think Dynavectors and Koetsus are close cousins, so I would expect similar results with the Dynavector. Or, to put it another way, whatever floats your boat.There is no 'correct' loading. Just to complicate matters, with valve stages the 47K loading is often just fine.
