Loading a Denon DL103R

Loading for DL103R

What loading for capacitance and resistance have Denon DL103R users found best.?
My options are 1K 499R 250R 100R 49R 10R
and 22pF 47pF 100pF 220pF 330 pF 470pF

Don't need capacitance as it is a MC. Mine is loaded with 150R. Try 100R and 250R and least capacitance as possible.

Thanks, Irealise now re the capacitance and have been playing with 15oR 100R and 50R. Thanks SGregory

A good rule of thunb is 10x the cartridge impedance for starters. Salt from there to your taste.

Are there any issues if loading with 0 ohm, i.e. working in current generator mode of operation?

I know a number of people who are doing this with the DL-103 and low noise bipolar op-amps, apparently it works just fine. I haven't tried it with mine - I'm using Partridge 977 which work great for me straight into 47K.. (and they're only abou $80 a pair on ebay.uk)

I just asked it because I own a DL-103 with a Dynavector PE-1 "Phono Enhancer" MC head amplifier. I could not find any circuit diagram from the latter, but I have the manual, and it states the input represents an "unusual" load to the cartridge. There are shielded transformers and opamps inside (without type number). I suppose it is an active/passive I/V converter.

I read in an old Elector mag,if I can recall correctly,that current gen mode, 0 ohm loading, might be dangerous for the coils of the cartridge,because of the currrent flow back to the generator.I do not know if that's true.
