The DAD mic pres found in the MTRX are of the extremely clean camp of mic pres. Some of the best in that category (very high definition -- it helps that they are so close to the converters.) But absolutely no colour and they aren't meant to be "driven" in the least (they have a lot of dynamic range to capture orchestral transients.)

So, noticing your Grace monitor controller, Grace mic pres, Gordon, Millennia, Merging Horus/Hapi, and Pueblo Audio would be of this category.
