sE Electronics DM1 Dynamite 1-channel Active Inline Preamp

With its state-of-the-art Class A circuit and hand-selected high-grade FETs, the DM1 boasts the lowest self-noise in its class. What's more, thanks to its dedicated output buffer amplifier, the gain boost it delivers is always a consistent 28dB regardless of the connected load. The DM1's output impendence is also the lowest in its class, allowing it to drive long cable runs while reducing susceptibility to RF interference, buzz, and hum.
