A cartridge that mates well with the Sutherland Loco phono preamp?

I have the Little Loco also and have the same question. I have tried an Ortofon Rondo Red and an Audiotechnica ART-9. Both sound very good, the AT better but it's probably just a better cartridge. From what I've read the cartridge's internal impedance is probably the most significant spec (the lower the better), so the AT's 12 ohms is pretty low but how does the AT compare with other cartridges with the LL? Don't know.

I plan to try a My Sonic Labs cartridge with impedance of 1 ohm shortly after the new year. Unless people chime in with other recommendations.

@ghdprentice I would normally agree, however the phono stage in question is a transimpedance design and so is not your typical stage. 

I am using a Well Tempered Amadaus MK II FWIW

The My sonic labs cartridges have 1 ohm impedance

My Ortofon has 6 ohms and I believe most of the MC Ortofons have around that as well

The Audiotechnica ART series have about 12 ohms as does my ART-9 

Many spec sheets don't list so you need to dig a bit if you can find at all 

FYI here is a review of the Little Loco MK II (the MK II probably being the subject of this thread) from stereophile Jan 2022. He says "But now, with the Ultra Eminent Ex driving Sutherland Engineering's Little Loco, I never want to change cartridges or phono preamplification again. These two phono products seem made for each other."

I think I'm gonna try one of the MSL cartridges with my LL MK II
