Bravo Audio SP1 12AU7 Class A Tube Stereo Amplifier

The Bravo Audio SP1 is billed as a Class A tube amp for headphones, but is actually a hybrid unit that delivers warmth, power, and clarity. That’s because the Class D amplifier provides plenty of even-keeled headroom while the included 12AU7 tube buffer brings an organic warmth and body to your audio. The SP1 is also compatible with EH6922 series tubes and comes with an onboard switch for further customizing the sound. With dual 20-watt channels, there’s plenty of gain on tap to drive most of your headphones—and thanks to just 0.2 percent total harmonic distortion, there’s tremendous balance for a tube amp. The SP1 covers a frequency spectrum of 40 hertz all the way to 18 kilohertz allowing for a solid amount of articulation for most of your source audio. Plus, with speaker pole outputs and multiple options for inputs, you can fold it into your setup with ease.
