Ampapa A1 Vacuum Tube Phono Preamp/Headphone Amplifier
A Modern Chassis With Tube Richness
Ampapa’s A1 Vacuum Tube Headphone Amp brings a beautiful combination of modern design and vintage tube richness into a desktop preamp that really sings. Suitable for general preamp usage, phono preamp functions, or driving your high-end headphones, the A1 packs the juice and the headroom you’ll need for virtually any listening situation. The impressive 16-to-300-ohm impedance range is perfect for higher-end IEMs or audiophile-grade headphones, while the equally impressive 106-decibel signal-to-noise ratio for RCA usage and 80-decibel ratio for phono usage is perfect for bringing richness into your desktop DAC or record player signal chain—without artifacts. Complementing the sound with a style that’s equally as rich, the A1’s platform-style chassis features lighting accents and exposed tubs that channel an almost futuristic look to house your vintage tube warmth.
