I have a Rhea and you can load at 75 or 125 ohms but not 100. Close enough.
My experience is not inconsistent with that of Dan_ed but I would suggest the quality of the tubes in your Rhea will be a factor. After spending considerable time finding quiet tubes, I now prefer to run my Rhea at the highest possible gain setting rather than boost the volume. I believe this is consistent with the Aesthetix viewpoint too.
I remember contacting the distributor when I bought mine two years ago. He had both a load and gain recommendation for my cartridge. I think it was someone at Musical Surroundings but I may be mistaken.
