Eddie Current

The premier manufacturer of vacuum tube headphone amplifiers for the audiophile


S T E P   I N T O   T H E   M U S I C . . . What is the sound of Eddie Current? The sound of engagement. Most other headphone amps sound pretty good at first, but in less than an hour of listening, either fatigue or boredom sets in. That's when you find yourself thinking about getting back to work, watching YouTube, or looking for a new amp. With Eddie Current amps, you'll never want to stop listening. They are designed to break the barrier between you and the music. This is why owners of Eddie Current gear eventually get fired from their jobs: they stay up too late into the wee hours of the morning listening to their amps.
