Trilogy Audio Designs 925 Integrated Amplifier - hybrid 135W

The Trilogy 925 integrated amplifier has strength in depth that will satisfy the most demanding audiophiles. It takes the integrated concept a significant step forward to deliver an involving musical performance that is truly memorable.

One box but no compromise .

At the heart of the 925 you will find many of Trilogy’s award winning technologies. The balanced input stage uses the 6H6П super tube to provide pure triode Class A, zero feedback voltage gain of exceptional linearity. The output stage has our unique zero feedback MOSFET and bipolar topology in a bridge configuration for 135w of power with impressive control.

The amplifier is fully symmetrical inside and out. Unlike many other amplifiers claiming to be balanced, the signal positive and signal negative are never tied to ground in the 925. A powerful and fully customisable input management system also interfaces with the outside world and other Trilogy products via TASlink.

The 925 design elements are all brought together seamlessly into an amplifier of superlative quality. It will serve music with a light, transparent touch and controlled, effortless agility. 

Standard finish is a soft, finely bead blasted natural aluminum. You can also choose one of our lustrous paint finishes at extra cost, or take advantage of the Chameleon Colour System which opens up a whole rainbow of custom finish possibilities.

As with all Trilogy designs a short, pure signal path is central to the 925’s design philosophy.

The internal architecture in the Trilogy 925 is fully balanced, from the relay input switching and volume control, right through to the valve input stage and bridge power amplifier. The signal is never converted internally to single ended to maintain maximum signal integrity.

Three fully balanced and three single ended rear panel inputs are switched via instrumentation grade ruthenium plated relays within millimetres of the rear panel connectors. A separately selectable auxiliary loop is provided. In addition, a 3.5mm jack on the front panel allows portable sources to be connected quickly and easily. A carefully selected audio grade digitally controlled potentiometer provides volume control and balance in 1.0dB steps.

Each channel has two directly coupled dual triode 6H6П valves that form the input stage.

This Russian military tube has outstanding performance, achieving both high transconductance and very high linearity for peerless audio performance. They provide all the voltage gain for the amplifier in a single stage. A carefully optimised servo ensures the valves operate perfectly symmetrically. Trilogy’s hallmark discreet HT shunt regulators provide the valves with pure regulated DC.

Providing only voltage gain, the valves are free to deliver the sublime performance they are noted for.

As they operate best as voltage devices, the 925 can deliver all the vibrancy and detail that valves can offer, without compromising operating life or reliability.

The 925’s unconventional output stage uses a small FET with the addition of a high current bipolar device.

The fast, agile FET only operates within the critical first watt region. An amplifier will typically spend most of its time in this power band at normal listening levels.
The bipolar transistors then seamlessly contribute high current as music conditions demand. This topology helps to preserve the vital micro detail that brings music alive, whilst simultaneously being able to source high currents for instantaneously moving the loudspeaker when needed.

The output stages are arranged in a bridge configuration. Each channel has two power amplifiers that simultaneously pull and push power to the loudspeaker. The principal benefit is that large currents are kept out of the system ground, keeping the amplifier stable and composed during large scale musical events. The output devices are configured to operate in a high bias state, giving a generous envelope of Class A operation. The relatively high dissipation, in conjunction with the high thermal inertia of the heatsink, keeps the devices in their optimum operating condition and improves sound quality. Feeding the 925 is a substantial faraday screened power supply transformer with separate windings and rectifiers for either channel. Custom Trilogy reservoir capacitors smooth each channel of the output stage DC and valve HT supplies.

The valve heaters and logic supplies each have their own power transformers to keep internal electrical noise to an absolute minimum.

The amplifier has a sophisticated monitoring system to maintain safe operation at all times.

Temperatures and critical voltages report to a dedicated microcontroller. An intensive R&D project produced specially formulated algorithms to monitor output current against time and frequency with great accuracy. This enables reliable discrimination between DC faults or demanding musical conditions, providing excellent protection but avoiding unwanted shutdowns.

Like all Trilogy designs, the 925 has peerless build quality, driven by Trilogy’s obsessive attention to detail. Premium and custom parts are used throughout.

Solid copper binding posts, PTFE insulated gold plated connectors, precision passive components all carefully selected to enhance sound quality and reliability alike. Conventional extruded heatsinks display strong resonant signatures and have been rejected in favour of custom, machined solid billets of aluminum. Each weighs in excess of 5kg. Their high mass and irregular form provide outstanding mechanical and thermal stability for the output devices.

This brings substantial sonic benefits as semiconductors are surprisingly sensitive to vibration and temperature changes

The power transformers are mounted on a thick machined plate of K-material.

This high metal, low resin content composite has excellent mechanical properties and superior self damping to metal. It provides additional damping and stiffening of the non magnetic chassis too. K-material is also used for the feet, providing the optimum interface between the 925 and the equipment support.

The perfectly weighted control and two machined stainless steel push buttons access the control menu hierarchy. All high level functions such as volume, balance and input select are quickly and intuitively accessible.

Remote control is via infra red handset, the machined from solid PRC is a perfect compliment. The dot matrix LED panel display is designed to be fully legible across a room. Brightness can be configured to track the ambient light level or is manually adjustable.

Each input can be left as factory preset or given a custom label of your choice which is displayed each time the input is selected. A gain trim can also be assigned to each input to equalise volume levels between sources. Balance control is available in 1dB steps.

Default start up volume and balance settings can be saved via the menu system. 

Phase inversion can be easily accessed from the remote handset for comparison whilst listening or set as a default within the menu. 

A real time clock provides multi event, seven day system switch on, switch off with external communication via our proprietary interface: TAS link. This allows you to fully warm up your system before coming home to listen. 

A sleep function provides power down after a selected period of your choice.

Trilogy Audio Systems at a glance

'The essence of music

- engineered'

From a passion to remain true to the essence of music, and by keeping all the key design elements in harmony, we create products of true quality.

Look at the objects around you in your home or work place; the chances are much of what you see is the end result of derivative thinking. By bringing a small improvement to what already exists; a commercial niche is filled and a small advantage over your competitors is gained. Here at Trilogy Audio Systems we do things differently. 

"Making some of the best-looking, best-finished and - appropriately - best-sounding kit in the UK today, but rarely shouting about it, is Trilogy." - Ken Kessler - HIFI NEWS

Nic Poulson is the principal designer of all Trilogy Audio Systems products.

Nic's background was originally in broadcast engineering, training with the BBC in the eighties. The corporation's legendary high standards made a deep impression on him. He learned that the way to achieve true quality is to strive for excellence in every area and accept nothing less. He went on to found Trilogy in 1990 and quickly earned a reputation for producing designs that reflected his core values of performance, reliability, pride of ownership and value for money.

Nic's designs can also be found in runway lighting systems, guiding aircraft safely to land at major airports across the UK. His success in the exacting industry of aviation is further confirmation of his breadth and versatility as a designer.

After studying in depth the inherent weaknesses in most mains derived power supplies, and their surprising impact on sound quality, Nic founded Isotek and revolutionised the concept of mains conditioning. Now the creative force behind Isol-8 Teknologies, he has delivered award winning designs which display none of the negative qualities shown by previous generations of mains conditioners. His products have taken the audio community by storm and are sold to discerning users worldwide.

His design philosophy is the key to understanding all Trilogy products.

Instead of deciding a price point and assembling a product steering committee chaired by a marketing manager, Nic goes back to first principles: identifying the fundamental questions at the core of each design issue. By carefully addressing and optimising each electrical design element to deliver the optimum solution, his goal of minimum compromise is achieved.

We complement this by taking great care over the realisation of the design. Beauty, reliability and user friendliness are essential qualities that must be present as a design makes its way through the myriad processes that make a physical real world product.

These are the reasons why our designs are enduring. From a passion to remain true to the essence of music, and by keeping all the key design elements in harmony, we create products of true quality.

Several years in the making, the latest generation of Trilogy Audio Systems components remain true to our original core values. Engineered from the inside out with real heart and soul behind them, they will provide lasting satisfaction, making music for your pleasure. We hope you will share the experience with us soon.

"I firmly believe that making exceptional products is a combination of knowledge and intuition, or passion if you prefer. My passion lay firmly with analogue electronics. I also have little or no interest in digital circuits. I understand what’s going on with them but have no feeling about them." - Nic Poulson

Trilogy 925

Il Trilogy è un vero strumento di precisione che, oltre ad analizzare e riportare tutti i minimi dettagli del segnale dalla fonte originale, riesce a ricostruire nello spazio con incredibile precisione la reale posizione di tutti gli strumentisti e degli attori in genere dell'incisione (questo concetto vale anche per le grandi masse orchestrali). Nel particolare viene addirittura "visualizzata" , ad esempio, l'intera tastiera nel pianoforte nella sua interezza, dalle ottave più profonde a quelle più alte. E l'ottenimento di questo risultato è sufficiente, di per sè, per definire la quasi "incredibilità" di quanto l'ampli possa raggiungere in termine di perfezione assoluta, con in più tutto il pathos profuso dall'interprete nell'esecuzione.

Ti invito al viaggio
in quel paese che ti somiglia tanto
i soli languidi dei suoi cieli annebbiati
hanno per il mio spirito l'incanto
dei tuoi occhi quando brillano offuscati.
Laggiù tutto è ordine e bellezza
calma e voluttà.
Il mondo s'addormenta in una calda luce
di giacinto e d'oro
Dormono pigramente i vascelli vagabondi
arrivati da ogni confine
per soddisfare i tuoi desideri.
