Symptom: Running a Benz Micro ACE M on a origin live conqueror arm. Purchased a JC3 and I am getting distortion on the highs and lows. The output of the Cart is .8mV. I'm thinking the Cart needs to be a lower output so that it will play nice with the JC3. Thoughts?

Are you using the MM or MC input on the JC3?

You may be overloading the mc input, try the mm and see if you have enough gain.

.8mv is still pretty low, that's not the problem.  Also, I would use the 100 ohm setting not the 47,000 ohm. The Benz M series is at 24ohms the JC3 only has 2 settings for MC and the 47,000 ohm setting is too high for that cartridge. Also, the JC3 has a AC polarity switch that you can use to eliminate ground hum.

Can you be more specific about the nature of the distortion? Is the distortion the same on all LPs? Are you sure you have overhang and VTA/SRA set accurately? The Benz has a narrow profile stylus, so set-up is especially critical. Is VTF set in the recommended range?

According to the manufacturer's spec, 47 ohm loading is too low for this cart - it wants to see something more than 240 ohms. If you meant 47Kohm, that's too high, and will make the cart sound bright.
