Cypher Labs Theorem 720 DAC - Announcement

The HifiHeadphones team is pleased to announce the new DAC & Portable Headphone Amplifier from Cypher Labs, the Theorem 720 is now available to be purchased on our website.

Cypher Labs latest creation, Theorem 720 DAC combines a fully integrated high-quality headphone amplifier with a high-end digital-to-analogue converter for PC, Apple and Android devices.

Delivering clean, high quality audio from iPod, iPhone, Mac or PC, the Theorem 720 DAC offers asynchronous conversion of the USB output, not only a pass through of the line-out. Two headphone outputs support single ended or balanced set-ups while a line level analogue output caters for connection to amplifiers or powered speakers. Volume gain settings optimised for all headphone types make the Theorem capable of driving even very demanding headphones with ease.

The large capacity replaceable Li-polymer battery charges Apple devices while playing up to 18 hours with a fast re-charge time of 4 hours. The battery features AC switching that is totally isolated for a clean power delivery.
