Audio & Entertainment · VACUUM TUBE · TONE CONTROL · TURNTABLE PREAMP
A vacuum-tube phono preamp and headphone amp with tone control, built to warm up a turntable's sound.

Warm up the signal
Classic JAN GE5654 vacuum tubes bring a warm, detailed sound to your turntable or line-level source.
Shape the sound
Rotating knobs let you dial in the tone to your room and your ears, no separate EQ needed.
Drives more than turntables
Beyond MM turntables, the A1 drives active speakers and a wide range of headphones for flexible use.
Built like it sounds
A solid aluminum, die-cast and CNC-machined enclosure with solid aluminum knobs gives the A1 a desk presence to match its sound.
