a suggestion that is not one of your three pre's above:
Nordstrand MM 2-band pre. A 'clone' of the original B00 2-band like in the original Stingrays. Carey did a wonderful job bringing a classic preamp back into existence. in-house testing here at the RGW ranch has us of the opinion that matching a Nordy MM4.2 with their MM 2-band pre yields a result that is near impossible to tell apart from the original unless you have the most astutely discerning ears (even then, you will only hear the difference when the bass is solo, not when in a mix or played in context within a band setting)

disclosure for those who are newer here and don't already know: I am a Nordy OEM builder. I do not re-sell preamps without them installed in an instrument. I chose to be a Nordy OEM by first having been a player who utilized their preamps - I chose to use Nordy pickups and preamps in my builds because I believe that every build I send out the door should cause me to hesitate in selling it due to me wanting to keep it for myself. I play what I build and build what I play
all the best,
R
