I have not but i'd love to try. My taste is quite similar to Crinacle or Timmy (gizaudio) so will try when i have a chance
Technically, I can tell from Audiophile’s hunch that the main “love“ that Crin and Timmy have is in favor of J-POP genre.
I‘m pretty familiar with Crin’s taste and his recommendations are very good fit to J-POP, especially mainstream high spectrum —1khz-20khz+ —female vocal type (Suis/Minami/Reol/Reona/LiSa/Dazbee/Ado/Aimer).
There are more technically talented J-Pop female singers like MISIA/Utada Hikaru/KOKIA, and they have wider octaves in singing, “Western style singing” which contains mid-bass elements.
And yes Monarch is indeed specialized for J-POP or other Asian major scenes
That mid-bass limited tuning of Monarchs may not suitable as a all rounder for Billboards tracks though, Billboard top runners have rhythm sections with heavy bass elements in focus. Those needs that “bass bleed” in order to sound engaged.
That’s where Thieaudio divided their product line into Monarch / Clairvoyance. Clairvoyance is tuned better fit with Billboards, Rock, those genre those need “mid-bass” and more “musicality“.
Although the only nitpicking for Thieaudio’s decision is that they set Clairvoyance as lower-grade set when compared to Monarch, means lower price, less hardware spec. It’s to avoid direct competition among their own product line ups, but that’s a bad call.
They should have set those two line up equally and let people decide which one their preference… and Monarch MKII is somewhat mixture of Monarch OG and Clairvoyance’s mid-point(actually more toward Clairvoyance) now, the identity in both tunings virtue is lost and it became more universally all rounder, simpler manufacturing process, more cost efficient, to the extent I see even a downgrade in carrying pouch shifted from original leather case to fabric generic one that comes with XINHS’s $20 cable purchase..
Thieaudio could offer more, and now the prestige seemed to be targeting what Monarch OG was pursuing.
