Whest 3.0RDT vs Trichord Diablo +NCPS

Hi, I have the chance of buying a Whest Audio 3.0RDT (not SE) at more or less same price as a Trichord Diablo w NCPS.
What would you suggest ?
How would you describe the differences between the two models, if any ?
Which one would be a better match, in your opinion, with my cart, a Lyra Delos ?

I own a Project RPM9.1x (9cc tonearm) + Lyra Delos + Electrocompaniet ECP-1
the rest: ARC LS7 + ARC 100.2 + B&W 804s

thanks, ciao
