Alpha 2 SE, Balanced Stereo Tube Headphone Amplifier

Miuaudio Alpha 2 SE — Balanced Tube Sound, Made Portable

The Miuaudio Alpha 2 SE is the refined evolution of our Alpha 2 — a portable stereo balanced vacuum tube headphone amplifier created for listeners who want the character of tube audio without being tied to a desktop Hi-Fi system.

Building on the original Alpha 2, the SE version features a revised and carefully tuned circuit with significantly reduced background noise, while preserving the rich tonal character, musical texture and engaging presentation that make vacuum tube amplification so distinctive.

True Balanced Tube Amplification

Portable balanced headphone amplifiers are increasingly common. Portable balanced vacuum tube amplifiers are not.

Alpha 2 SE was developed to bring these two worlds together. Its balanced architecture combines the advantages of balanced headphone listening with genuine vacuum tube circuitry, creating a portable amplifier designed for listeners who value musicality as much as technical performance. Through the two viewing windows on the aluminium chassis, the vacuum tubes remain visible — not simply as a design feature, but as the analogue heart of the Alpha 2 SE.

High-End Listening Beyond the Desktop

Compact enough to travel with your portable audio setup, Alpha 2 SE lets you bring a genuine tube-based listening experience beyond your listening room. Pair it with your favourite portable music source and headphones or earphones to create a remarkably sophisticated personal Hi-Fi system wherever you go.

Its robust aluminum enclosure and protective carrying case also make the Alpha 2 SE particularly suited to enthusiasts who want to take serious headphone listening with them.

Balanced architecture. Vacuum tube character. Lower noise. Portable freedom.

Miuaudio Alpha 2 SE — high-end tube listening, wherever your music takes you.
