The task of moving the delicate membrane of a headphone driver is a very different to energising the reactive complex impedance of a multi driver loudspeaker. With much less mass to move and without the masking of listening environment and room interaction, the small signal integrity of an amplifier becomes even more critical than that of a regular power amplifier.
A different approach to design is required. This has led us to a very different solution to most accessory mass market offerings.
The Trilogy 933 is a clean sheet design with the same natural presentation and vibrant musicality found in our award winning pre and power amplifiers. Its a subtle, but crucial distinction: we like to think of the Trilogy 933 as an amplifier for headphones, not a headphone amplifier.
