Like the others, I suggest add mass to the WTR tonearm or get a higher effective mass replacement. I recently ( this week) experienced an epiphany with my similarly low compliance Koetsu Urushi. I’ve owned it for about 10 years, used it in a few different medium mass tonearms, was never blown away by its SQ. Last week, in a last ditch effort to make it sing, I mounted it on my FR 64S on a Victor TT101 turntable. Using an 18g Ortofon headshell. Holy cow! I never would have believed the Urushi could ever live up to its expectations. But now it does indeed.
Also, I am familiar with the WTR tonearm in a negative sense of the term.
