Sound of a Tube Amplifier

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. 

You can listen all day with over 8 hours of battery life.


2 amp 5 v charger; 2 silicone straps to bundle devices; USB charging cord, half-meter mini to mini cable. We suggest using a short high quality mini cable, such as our 3.5mm straight cable, for the shortest path.
