Replacement for my Benz Micro Ruby

Hi, I am close to having the funds to replace my old Benz Ruby. I have had this for something like 20 years. I did have it retipped a few years back.

My system

VPI TNT w/JMW Memorial 12" arm

Manley Chinook phono stage

Audio Research LS15 Pre

Proac Response 3

VTL tube monos

I would like to be at a price point for a new cartridge around $4K

I understand the Benz line isn't being imported any longer. I love the sound of my system and don't want to change the sound by buying a cartridge that has a different flavor.

Koetsu Standard Rosewood, Sumiko Palo Santos, Kiseki Blackheart, Kiseki Purple heart and Koetsu Black Goldline are all around my price point.

any insight is welcome. .Hard to know what your buying only based on ads and magazine reviews.
