My upgraded PL2000 Preamplifier signal output comes right off the output of a Texas Instruments/Burr Brown "SoundPlus" OPA2134 SMT OPAMP (formerly RCA 4136) via a BrownDog adapter P/N 060601 and through a Panasonic 22uF/63V DC Blocking Capacitor in each channel. There is no pulldown resistor.The Acurus has a specified 50 ohm output impedance.
I can find no reference for the PL2000 Output Impedance, but the output impedance (Zo) of the OPA2134 is 10 Ohms.
My PL1000 Autocorrelator Noise Reduction System only has a 47K pulldown resistor on each channel output. And I like it that way.
