My phono pre also has the large step from 100 ohm to 1000 ohm loading. I tried a Y-adapter to add parallel loading plugs, but decided I like the Audioquest “Hard RCA Splitter” better. See https://www.audioquest.com/accessories/splitters-connectors-adaptors/adaptors/hard-rca-splitter-male...
I use a resistor about 1000 ohms in parallel with the 1000 ohm setting to get to about 500 ohms load resistance. I made a bunch of plugs to try various loading between 100 and 1000 ohms, and settled on the 500 ohms loading.
