With Germanium transistors, the Siemens V276A is one of the most highly regarded vintage solid state mic preamps. The high frequencies are smooth, the low frequencies are full and punchy, and the mid-range has a nice presence with a bit of grit. Overall, it has a very warm and beefy color character. For what it's worth, the A version is a bit brighter on the top-end than the original V276 version.
