Klimo type phono stage from China

fills the roll of dual inputs. 1 MM and 1 MC. 

One MM and one MC does not fill the role of dual inputs in my book. That falls quite short compared to phono-stages that have two inputs, where each is configurable for either MM or MC independently.

I have two LOMC and a phono-stage with two inputs that support them. I very much doubt I'll ever have one MC and one MM. I use one input for a stereo cartridge, and the other for a mono version of it.

Duly noted. 

having at least one dedicated MM input is optimal with a SUT, you can go down to a 0.15mV or thereabouts with no noise penalty. With the Klimo, the MC input is best used with carts higher than say a 0.45mV lower than that and noise is an issue.
