Cartridge loading

I have a Benz Micro Gullwing low output cartridge and supposedly has a load rating of >400 ohms. I am using an Einstein Turntable's Choice phono section which had 69db of gain and has four sets of interchangeable plugs to vary the load. The problem is, the highest load available is only 300.

When I checked with Einstein they said there is a 500 ohm "load" when using NO plug. They don't make any custom plugs so I am stuck with one of the four sets of plugs that come with the preamp. What does that mean sonically or electrically? What changes could one expect if a 400 or even 1000 ohm load could be applied? Is there an inherent problem with using no plug in the SE slot?

Thanks in advance.

Very close is totally not a problem. What the load does is change the 'tilt' of the output slightly. SO if you want it a little brighter, got for the 500 ohm. If you want it a little less bright toop end go for the 300ohm.
My Audio Research Sp-15 has a selectable impedance switch on the front panel. and I can switch from 30 60 400 800 47K
And switching it changes the 'tilt'/brightness a little

And no problem with no plug in the slot.
