Can you run the HANA SL MC at 100 ohms?

I find the reasoning behind the loading kits like DB Systems, at the least, questionable. If my phono pre or SUT has a fixed input loading of 100 ohms and I add a 300 ohm resistor in parallel, what is the resulting load impedance? Hint: it sure ain't 400 ohms as is widely believed.

FWIW, I run my Hana SL into a SUT with a fixed input load of 100 ohms and it sounds excellent.

Then I wonder why @andysf suggested them as a remedy in response to the original post which asks:

Surely, neither you nor @andysf propose plugging a Hana SL into a normal 47kohm MM phono input and adding loading plugs. I tried my Hana SL direct, that is, without a SUT, one time and the sound was thin and lacked dynamics. I could hardly wait to remove it!

No. My Rothwell MCL SUT is resistor loaded. https://i.ebayimg.com/00/s/MTIwMFgxNjAw/z/8r0AAOSwYXVYya~I/$_57.JPG?set_id=8800005007
