I would think the Core Sound 4Mic might be ideal, as it provides the proper
power for the TetraMic. I've been intrigued by the TetraMic myself, and have
a Traveler, but would also need 4 of their power adapters to use it with
the Traveler, so it gets a little cumbersome.

Right. The 4Mic is undoubtedly going to be pretty expensive, and it may not
come as close to the ultimate in preamp performance as something else. But
it doesn't appear that preamps using VCA devices are very common yet.
There's a new chip out that may change this.

Core sound themselves are recommending the traveler and apparently the
apogee ensemble can perform in the same way. The pres in the traveler
are surprisingly good (when they work - I had to send my first unit
back and later discovered that the problem I had was quite common) and
a lot of people are using them with the tetramic with success. There
are a quite a few digitally controlled pres from the likes of
focusrite (4 channel liquid thing) grace, rme etc that could all match
gains with the same accuracy but I doubt the 4mic will be as expensive
as any of these and depending on what you are planning to do with the
mic, you might find the portability of the 4mic more useful than any
of these anyway. I'm also interested in the 4mic and I'm intrigued by
its ability to mux the A-format signal (4 channels) into 2 recording
channels. I'm hoping that I will be able to use it with my R4Pro to
use as a 6 channel recorder (tetramic + 2 spare channels for shotgun
or whatever else).

Two RNPs would do it, too.

Metric Halo has recently upgraded some of their boxes. I'd consider
looking for a plain old Metric Halo Mobile IO 2882 if you can find
one. They are quite rugged, single spaced and sound very very good.
Needs a Mac to operate its digital controls though. The +DSP models,
while pricey, are even nicer yet.

No tengo Mac!

I've got so much good equipment, all I really need is a preamp.
