Note to Rwwear: Thanks for your caution, but you are just a little off-base. Your comment refers to the original amps (DNA-0.5, -1, and -2), not the current DNA-125, 225, or 500. The original amps had protection circuitry that was intended to sense potentially damaging DC levels, but could be triggered by high levels of low-frequency noise. This happened rarely, but I have seen it caused by a variety of tube preamps. A simple adjustment will fix this. The newer DNA amps are designed differently and are not sensitive to DC or low-frequency noise.
4yanx's comment is right on - tube preamps tend to run at rather high gain, so a high-resolution volume control makes life a whole lot easier.
