The Onyx (Sugano) was a complete disaster with my Pluto 9A.
In contrast, this arm matches almost well with the Goldfinger (similar mass/different compliance). It seems its a matter of compliance more than cartridge's mass. But this is a contradiction as later, after mounting the Denon DL103 (even less compliance than Onyx) the results were also unacceptable , but better than Onyx due to the lighter Denon body.
What was really happened ?
The Goldfinger has a phenomenal trackability especially in contrast with the Onyx.
This alone was enough for me to stop trying to find a proper arm for Koetsu.
Of course those are examples of extemely wrong matching (uknown Pluto effective mass) & if you dare to test for trackability, you may aware that you have a damaged Koetsu sample.
Now with the Colibri (less than half the weight of both & 35 Cu compliance) my Pluto makes the perfect pair.
So, don't bother. You simply can't trick the formula.
The Alphason HR100 is a great arm for Denon DL304, so maybe matches equally well with Koetsu Black.
If you really like the unique Koetsu sound, you must first purchase a robust & preferably 12" arm. Then, pair them with an electrostatic speaker & some OTL power amps.
Somehow I feel that letting your Koetsu decide for your system building, maybe is a little too much love for her.
Sorry for I can't help a lot, but I value Koetsus even less than DL304 and way below the DLS1. They have much character to enjoy, but the trade-offs are many more.
Having said that,I admit that If I would like electrostatics (over horns) & OTL (over SET), I definitely give a chance to Koetsu.
It has a beauty unable to find elsewhere in the chain.
