Trilogy 933

Headphone Amplifier

(Natural) –

UK Distributor Demo Unit.

Very Little Use - (Immaculate Condition)

Missing Factory Packaging:

 

On offer is a Trilogy 933 Headphone Amplifier (in Natural finish) in Immaculate condition (Very Little Use)…this amplifier was the UK Trilogy distributor’s demo unit, and has been used very lightly. The system has been fully manufacturer refurbished (checked and serviced) prior to being offered for sale and is supplied with all the originally supplied accessories. The packaging was ‘misplaced’ by a UK dealer (whilst on evaluation loan!)…It will be packaged to ensure safe delivery. The system comes complete with 12 months manufacturer’s UK warranty.

 

Prior to being offered for sale this unit has been fully ‘manufacturer refurbished’ by Trilogy Audio’s service agent (on behalf of the UK distributor) to ensure that it is supplied in immaculate condition.

 

As such it is an excellent opportunity to acquire this stunning, highly acclaimed, Headphone Amplifier in immaculate condition, at a very reasonably discounted price.

 

 

 

Some words from Trilogy Audio:

 

Trilogy 933:


Amplifier for Headphones:

 

We think of the Trilogy 933 as an amplifier for headphones, not a headphone amplifier. At first glance this may seem like a non-distinction. When we decided to build a headphone amplifier we took an audiophile's perspective, not that of an accessory manufacturer. The implementation with 20 years’ experience in amplifier design has led to a very different solution to most mass market offerings. As a result, the 933 displays the same natural presentation and vibrant musicality found in our award winning pre and power amplifiers. Add in the convenience of two inputs, full remote control and the reassuring build quality that is the hallmark of all Trilogy products, and the 933's distinctiveness becomes clear.

 

Barely moving the delicate membrane of a headphone driver has very different requirements to energising the reactive complex impedance of a multi driver loudspeaker. Without the interaction of a room present and appreciable mass to move, the small signal integrity of the amplifier becomes even more critical. A different approach is required. The 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.

 

The discrete topology is implemented with carefully selected components to deliver amazing resolution and drive capability for any high quality headphone. Housed within an aluminium billet which is CNC machined from solid, the enclosure forms the ideal thermally stable, non-magnetic, non-resonant platform for the amplifier's active circuits. The generously rated external power supply can be remotely sited to keep stray electromagnetic fields at bay. A faraday screened transformer and soft recovery rectifier diodes are complemented by a custom wound input choke. The choke input topology smoothes out the current pulses demanded by the custom reservoir capacitors, much like a flywheel, keeping the power supply's dynamic noise very low. In combination these two halves 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.
