AlgoRhythm Trio Portable Vacuum Tube Headphone Amplifier
The AlgoRhythm Trio is a battery powered tube amplifier designed to deliver a rich warm tone. The amplifier is simple to operate with separate power switch, volume knob and two level gain setting.
The Trio has a superb black background and a clean, clear, spacious full sound, with the pure midrange you can only get from a tube amplifier. The result is a warm and smooth dark tonality and overall large soundstage and dynamic response.
Charge your AlgoRhythm Trio using a computer or wall wart of 5v and up to 2amps. The enclosure is machined from a single durable block of aluminum. If you have any questions or need service please contact us at firstname.lastname@example.org.
