TRILOGY AUDIO SYSTEMS
Trilogy manufacture a wonderful range of English hybrid ( transistor/valve ) audio electronic equipment. They have a distinguished history and we are proud to carry their range.
We invite you to have an audition which can be arranged by contacting us and also to visit the manufacturers website for more information about the current Trilogy range.
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.
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 Trilogy designs are enduring. From a passion to remain true to the essence of music, and by keeping all the key design elements in harmony, they create products of true quality.
Trilogy 925 Integrated Amplifier
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.
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.
Trilogy Reference Products
915R Reference Preamplifier
The 915R preamplifier is Trilogy’s superlative statement pre amplifier, a culmination of decades of design knowledge and a no compromise brief. The sonic character of this design being as close to the live source in performance, has been realised. Boldness and subtlety are delivered with equal aplomb.
Openness, balance and agility produced with this preamp make music tangible, the listener is not left lacking feeling a nuance has been lost. Lithe sonic landscapes imbued with just the correct scale and perfect imaging.
The control menu is accessible through a highly intuitive rotary encoder, this facilitates all the common functions being readily available with thoughtful implementation communicated through a large red LED dot matrix display. Display brightness, customised labels and gain trims for each input, film mode, security bonding, sleep countdown, timed system switch on via TAS link, and remote operation enable you to make the 915R a bespoke experience - an interface that is a joy to use. An optional security PIN code can be entered at start up which in the event of theft would render the unit unusable.
This is a preamplifier that anticipates all the users requirements. The inputs can be named individually, and channel balance configured to suit. Dig deeper into the menu and you will find the display of valves’ work hours or temperature read of connected Trilogy amps, real-time bar graph instead of volume level, days of week and the ability to schedule on and off times to everything connected via TASlink.
The gain stage uses the 6H6P super tube mounted in a billet compartment for the voltage gain, this tube performs exceptionally well in audio applications and its associated frequencies with true high fidelity and low distortion. A series of three transformers feed the power supply, the design actively shunt regulates the valves high voltage supply. The voltage rails ability to both sink and source current allows it to be both stable and quiet. Output is provided by the renowned Lundahl transformers.
It’s apex level topology is only equalled by the attention to its casing and detailing machined from billet alloy with the attention of a purist. The philosophy of utilising the optimum technology to solve a problem is the Trilogy ethos, encapsulated in the 915R preamplifier.
The preamp is supplied as standard with the stunning billet PRC remote, and a quality ISOL-8 IsoLink Wave power cord.
The 915R features a comprehensive range of inputs and outputs ; TASlink RJ45 socketry on the far right and a number of connections by Cardas (RCA) and Neutrik (XLR) in-between. There are six inputs (3x RCA, 3x XLR), four outputs (2x RCA, 2x XLR) and one RCA send (record) out in total. One of SE inputs can be also used as a return channel.
995R Reference Mono Power Amplifiers
The 995R is Trilogy Audio Systems much anticipated mono power amplifiers, finally brought to fruition after four years of research. Dedication that is evident in all Trilogy family products.
Truly monolithic and architectural in form with details such as machined fins optimised to dissipate heat by clever design via massive radiation surfaces. The considered form is only equalled by its uncompromised internal design.
As many Trilogy products that harness the strengths of both worlds, the 995R is a hybrid machine. These units via a discrete selector button are able to be cycled through three modes, class AB, A and eco A. The last mode behaving as class A whilst when the music is playing, however transistor bias is significantly decreased to reduce power draw if there’s no signal present this is both stable and has the advantage of the minimum of performance sacrificed.
The unit measures (W x D x H) 190 x 460 x 350mm and weighs 38 kilograms which reflects its thorough design rationale. Class AB delivers 200W into 8Ω, Class A mode outputs 40W (usable 55W) with the same load. Frequency response is 5Hz – 100KHz (+/-0.5dB) and gain on SE/balanced inputs is respectively 31 and 25dB.
Trilogy 995R is not just beautiful on the surface. The circuit has no feedback, is fully balanced and also features a bridged output stage. Its hybrid topology involves two 6H6P valves as voltage amplifiers, whereas small linear MOSFETs on duty with 12 Japanese Bipolars form the product’s push-pull compound stage. The PSU based on a large shielded toroidal transformer and custom caps enjoys full choke input supply. Featured is Trilogy’s proprietary TASlink network which the owner may choose to utilise based RJ45 sockets allowing connected Trilogy products to communicate and extend functionality across the system, providing details such as run time, or scheduled operation features accessed via TASlink enabled Preamplifiers.
Once again Trilogy has made a product that defies aesthetic convention and made a compact mono power amplifier with truly arresting performance. Statement amplifiers from a true British Independent. Reviews have stated the 915R /995R Pre/Power combination to be the very best of their kind.
