Dynavector Cartridge Load 100ohms or 47k ohms?

I use 17D2 Mk.II with Naim Prefix K phonostage which has fixed 560ohm/1000nf impedance/capacitance. The result is nothing short of amazing,I love the sound- it's neutral,balanced,detailed and dynamic without hint of brightness. Deck is LP12 with Naim Aro arm.

Thanks for all the responses.

dougdeacon, I spent last night experimenting and your post was right on. As I moved from 100 to 300 to 1.1k to 47k the detail seemed to improve and open up. But after listening for awhile, I realised the bass was missing and it did seem like the highs had more weight giving the impression of more detail. I think 100 or 300 will be the best for my setup. 300 sounds the best but 100 eliminates some brightness.

Thanks again!

The higher the input resistance, the lower the damping factor is going to be and the more likely it will be that your MC cart. will have a rising high end and experience ringing. The lower the resistance, the greater the damping. See Bob Hagerman's excellent discusion of cart. loading on his web site. Generally MCs will prefer a lower load with a SUT than with a head amp or gain stage. I think this is because the lower load enhances the current output of the cart. and a transformer is a device that converts current into voltage. Whereas a head amp is looking for voltage and will do better at a little higher loading. For a short while I had thought that my Sheltor sounded better at a higher load; until a singer hit a note that almost drove me out of the room. A lower load brought things under control.

really depends on your tonal balance of your system and what sound you are looking for.
I did have my XV-1 on 250ohms for some time, then about 4 mnths ago I tried on 47k. Currently I prefer 47k as it seems to let more upper frequency extension and flow in my system.
try for your self and pick what sounds overall better for you.

Dougdeacons answer and methodology is spot on IMO.and all other posts are good points as well IMO... I also use the 17D2MkII on a JMW10/Aries combo, but with a Bent audio SUT into an ARC PH3SE. For me, experimentation similar to the way he suggests with loading, I find the 100 ohm load just right, even with the SUT..Lower values than 100 tend to sound more closed in...and values above 1000 are "brighter" sounding in my system and although 47K allows a more "open" sound, the HF lacks coherence and the bass is too soft. I used to think that a good rule of thumb is to go as high a load value as possible so that you could keep the virtues of a MC( airyness and openness) but not too high that you lose balance in the bass and HF, and to some extent this is still true, but I think it's wise to go by the Cartridge manufactures recommended load as a starting point and let your ears decide which is right in your system. Best of luck..Ken:)
