There are just to many that fit that criteria to mention. I have never had a problem using the RE-20 with any high end professional external outboard mic preamp. When I do VO sessions, I usually start with my Focusrite Red-7, which happens to be a long time industry standard for VO work, and I rarely need to try anything else.

Focusrite Red-7

Wow that Focusrite Red-7 is a sweet looking rig, At least to a low end new-be like me.
Now I have to ask one of those questions;
How many I/O does it have, I mean does a single mic
plug direct to the red 7 and then out to the board.
I only have a small home studio and am just trying to learn
for the future. I have a whole two Phantom power supplies, LOL
and is it the same as a mic pre amp.
Now I'm dumb.

Yes, the Red-7 is a single channel unit with one output that has separate mic input and a line level input. Line level outputs such as those on external outboard mic preamps connect to line level inputs on audio gear such as a mixer.
