van den Hul Colibri, Koetsu Rosewood Signature, SoundSmith Sussurro Mk ii

After years of focusing on medium to high compliance MM and MI cartridges (and a handful of old piezoelectrics) in various turntables, I'm finally looking to add my first serious MC cartridge.  I've long been interested in either the Koetsu Rosewood Signature or the van den Hul Colibri (XGP/XGW) and had planned to go with one of those carts.  That said, I've seen enough glowing reviews of the SoundSmith Sussorro and its progeny to make me seriously consider that as an alternate route.  I would love to hear thoughts from anyone who has experience with more than one of those carts.
The cart will be mounted in a Moerch DP6 (yellow) as the second arm on a Thorens TD 124.
My listening tastes are eclectic, so I'm particularly interested in how the carts handle a diversity of music.
Thanks in advance.
Best,
Carroll

The Mørch should work just fine with the Rosewood, especially with a blue arm tube. Way back I tested an Onyx Platinum in my (then) Syrinx PU3b with an effective mass of 11g and it worked beautifully.

The paramount issues are the quality of the arm’s bearings, its general construction quality and tolerances, not adherence to a compatibility table which dates from the 50s and is likely quite incorrect. The Mørch scores high on all three and I’d have no doubts about using it with a Rosewood.

I’d still buy the Colibri though.

A low compliance cartridge on mid mass tonearms (or on a light mass tonearm) may be "fine" only for those who does not care about theory of resonance frequency described here. It’s easy to measure tonearm/cartridge resonance with Hi-Fi Test LP.

8g "yellow" armtube suggested by the OP. It’s a bad choice for a very low compliance cartridge! 14g "blue" armtube is better, but not ideal.

Everything can work until there is an issue with some slightly warped records and stuff like that.

There are tonearm with effective mass twice as much compared to Moerch "blue" and they are made for low compliance MC

Koetsu is not just a low compliance, it’s an EXTREMELY LOW compliance (7.5 cu at 10Hz)

Ortofon MC2000 could be your last LOMC if you have all those Moerch arm tubes, because it is a high compliance MC. But only if you can find a dedicated SUT or special current injection type phono stage (or very high gain phono stage).

Diamond cantilever Dynavector KARAT 17d2 mkII or higher in this series is also perfect choice! It does not require high mass tonearm.

P.S. For a very low compliance cartridges you really need another tonearm, with much higher effective mass.

I have an Ortofon Windfield and hundreds of records.  Never heard mistracking.  Not knocking P/L design....just sayin

I'm surprised nobody has mention Lyra cartridges.  The Delos and Kleos carts are quite good.  Not thin or too analytical like the early Lyra's, particularly the ones with the ceralloy cantilevers.  They are medium compliance carts that will work with your heavier arm tubes.
