Trilogy 933 Amplifier for Headphones

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 Trilogy 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 Trilogy's 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.

The svelte amplifier enclosure is machined from a solid billet of aluminium. Its hefty 1.3kg mass provides outstanding physical and electrical isolation for each of the active circuit elements as well as a stable thermal base for heatsinking the output devices.

The Trilogy 933's amplifier is pure single ended Class A, employing active constant current sources. Each channel has just one continuously biased output device. The output waveform is therefore completely free from crossover distortion and has excellent small signal integrity.

DC coupling removes capacitors in the signal path, enhancing detail even further. The discrete topology is implemented with carefully selected audio grade components to deliver amazing resolution and drive capability for any high quality headphone.

The improved external power supply can be remotely sited to keep stray electromagnetic fields at bay. A generously rated, faraday screened transformer and soft recovery rectifier diodes are complemented by a custom wound input choke.

The choke input topology smooths out the current pulses demanded by the premium Mundorf reservoir capacitors, much like a flywheel, keeping the power supply's dynamic noise very low.

The rear panel offers the user two selectable stereo inputs via high quality gold plated phono connectors.

The Trilogy 933 can stand alone as the cornerstone of a headphone based system or connect easily to any existing preamplifier.

Volume, mute and balance which are all accessed by the supplied remote control only.

The front of the amplifier has an arc of LEDs which conveniently display the chosen settings which are stored for the next time the Trilogy 933 is powered up.

The amplifier is monitored for safe area operation at all times and is automatically muted for power on and off.

In combination the Trilogy 933 elements form a whole greater than the sum of its parts. The Trilogy 933’s performance bears all the traits you would expect from a full sized Trilogy amplifier: coherence, precision, resolution and effortless musicality. The Trilogy 933 is truly a class leading amplifier for headphones.

Available in natural silver as standard. Extra cost finish options are our standard paint finishes, and almost unlimited custom colours through Trilogy's Chameleon System.
