High output MC cartridges


I'm looking to replace my MI cartridge with a HOMC cartridge.
I've narrowed it down (price/output mV) to either the Dynavector 20x2 MC, or, the Sumiko Blackbird MC .
Before I take another plung .... I thought I'd run it by the AG community to see if anybody out there has experience comparing these two offerings?

I think there is only one reason people buying HOMC cartridges, the reason is the phono stage that can’t handle LOMC.

But if they got a decent MM phono stage to handle MI then a decent SUT (or headamp) will help to handle some decent LOMC with the same phono stage.

Instead of any HOMC i would recommend to try some killer vintage MM or MI with superb cantilevers and best stylus profile.
The only time I’ve ever purchased a HOMC was because I got a really good deal on it. It is my 2nd best cartridge, a Van Den Hul MC Two Special.  Maybe my best.  The fact that it's a HOMC doesn't necessarily make it a bad cartridge. 
i have the Blackbird - very happy with it - using all tubes, VPI Prime and 8" full range open baffle DIY speakers from Decware. 
I purchased the blackbird HO as a package with project 9.1 turntable.  I liked the way it sounds but after a while  it became fuzzy sounding.  I checked out the stylus and thought it might be dust in the generator.  Long story short I blew away the fragile wires with a gentle puff of compressed air. My biggest audio blunder. Soundsmith could not or would not repair it.  Andy in Washington did and it is now a back up.  
Beware the Sumiko open cartridges.  I also run a Dynavector LOMC and I like it.
I had a Dynavector 20B on an Empire 698 TT. The combination sounded excellent!
