I also wouldn't mind an Undertone Audio MPDI-4 or a pair of MPEQ-1s. Those kinda seem like desert island pres.
I’ve used those a bunch Nice but not super colored though. Nothing like Neve or API. I was never compelled to purchase any. The eq is super flexible though.
Flexible and super confusing for me. I was using a pair and trying to make some quick tweaks during a tracking session and finally gave up and went into something else. After the session I dig into the manual description and was still confused as hell. Sometimes being able to do that much just turns me off.
I don't think I ever had a "fantasy rack" but I really do like what I have now and I'm not actively looking for any mic-pres. Currently, I have a 2-channel Hardy M1, a Demeter VTMP-2c, a Sebatron Axis 200VU, and a Hendy DaVinci. I also have a UA X8p and some of the unison pres but it's the outboard stuff that I really enjoy.
