Phono cartridge Goldilocks


I recently sold my Koetsu RSP because it way way too dark in my system. I bought a Kleos SL as I had several recommendations that it provided great clarity and treble extension. Well it does, but perhaps too much for the system.

I am looking for something that fits between the two in terms of overall speed, clarity and upper mids-treble presentation. One person recommended My Sonic Labs.

The system is:

Schroder SQ reference arm on an SP-10/Steve Dobbins plinth table.
Coincident phono stage and Frankenstein 2 amps
Audio Kinesis Zephrin speakers

Budget is around $5k-$7k and a used cartridge is fine.

I also have a benz micro LP-S mr and feel that it is a killer cartridge.  I cannot recommend it more highly, if you can find one.   
FYI on the Benz Micro LPS. My understanding is all new production has the micro-ridge stylus. You could confirm with Musical Surroundings, the distributor.
 
“First, yes, there has been a changeover with the LP S. Benz has gone to a micro-ridge stylus (thus the “MR”). Second, so far I think the Benz LP S-MR is one of the two or three best cartridges I’ve had in my system. It is outstanding.” – Jonathan Valin, The Absolute Sound

I agree completely regarding the Benz. ...a great cartridge...too bad they aren’t made any more.  ..a cautionary note.   They are very heavy and might very well benefit from a heavier counterweight for the arm.
