What controls/adjustments are needed for phono pre

I have a Herron phono pre and there is only one switch, on/off. Herron feels any other option potentialy impacts the the signal. pretty hard core.

Hello, Generally speaking,you want to be able to adjust the resistive loading and gain for moving coil cartridges.Capacitance and gain on moving-iron/magnet cartridge.Some units have a high gain for coils and low for mm/mi.There are units that allow high frequency contours and even phase inversion,if desired.Hope this helps! Happy hunting.

Not sure of the difference betwen control resistive loading and capacitance.Would it be on same control?pardon my ignorance of the basic electronics here.Also what about RIAA curves?I have a lot of 10" jazz lp's and heard that early LP's could vary in their RIAA setting.I know that if I was into 78's I could get a KAB made unit with all the different settings from 30's and 40's btu I imagine it wouldn't be as good sounding as some sudiophile phono stages.It seems more like an archivists tool.I just knoiw thatI am going to want a deck probably that can accomodate a stereo cart,a quality mono,and another with proabably a detachable headshell for beaters and 78's (I allready have a Denon DJ table to that end).Getting one phono section for about 4 diggerent types of discs ain't so easy!!!!!!
