PS: The internal resistance (DC resistance) of the 17D2 cartridge was found here:
http://www.dynavector.com/products/cart/e_17d2.html
Dynavector recommends loading the 17D2 at 100 Ohms (or higher) resistance. I found 200 to 300 Ohms sounded the best with my setup but experiment with other settings to find the best sound with your system.
