You've run some pretty fancy MC's, but the _______ MM cartridge really impressed me

OP here....Let’s accept any high output cart including Moving Iron. I apologize for not being specific. I’m actually interested in Grado, along with Clearaudio and Sumiko. I just bought a Luxman PD 151, and am thinking of going with a high output (MM, MI...) cartridge in an effort to keep my second system simple. At this point, I’m just looking for something special. I’m usually willing to sacrifice detail for tone and emotion. Price range is $600-$1500. 

Another Grado fanboy here! BTW, do you know the mass of the tonearm?

I run a Clearaudio Maestro V2 Ebony in an SME IV tonearm on a Michell Engineering GyroDec. Sounds fine to me and tracks every disc I play, effortlessly. Including DD LPs cut at high levels. Sound quality using MFSL One-Step Ultradisc is about as good as it gets IMHO.

Grace Ruby. Also other more rare Grace MM cartridges, with advanced styli; I forget the nomenclature. Also vintage Acutex (MI) and B&O MMC1 and MM20CL (both also MI). These will blow away many mid priced MCs and all HOMCs I have ever heard ( includes some Sumiko, Transfig Esprit, Benz Glider 1 and 2). These are only my opinions based on listening in my two home systems.
