Ahead of the curve Trilogy has opted to fittingly make the first Special Products Division a component where nuance and tangibility is etched in fine detail - the electrostatic headphone energiser. A fitting first statement product for Trilogy Audio Systems SPD range, built with meticulous sonic craftsmanship.
After trialling variations of the Stax circuit used by many other manufacturers Nic Poulson realised that accepted wisdom and circuitry failed to advance the product to Trilogy design goals, to only ever evolve and improve.
The SPD H1 circuit is unique in terms of a solution. The design consists of two toroidal transformers, one for heating the triodes, the other for the rest of the H1. The vacuum tube circuit utilises high transconductance type military specification tubes. One pair of 6C3 input tubes and one pair of 6H6 output tubes, having a service life of approximately 5000 hours and can simply be returned to Trilogy for replacement.
The H1 is a pure Class A fully balanced circuit with both wide bandwidth and zero feedback giving a pure communication between the listener and the music. Naturally on this no compromise design wiring is teflon coated point to point silver plated copper. The Stax sockets are PTFE/Teflon with gold plated contact surfaces.
The H1 provides palpable bass and a forthright and authoritative midrange, in addition to the quality airiness that electrostatic headphones are so renowned for. The ephemeral yet conversely frustrating qualities of the traditional experience of electrostatic headphone presentation have been addressed. It has taken time to reverse conventional thinking, but the result was worth it. Experience the openness and pure escapism the H1 provides.
To the rear the SPD H1 features 4 inputs/ 2 x RCA 2 x XLR, and one pair of Stax sockets elegantly recessed into the front fascia.
We make a direct mode model (DMV) which allows the user to select inputs remotely and a more fully functioned remote that includes additional operations as volume/balance and mute. The direct mode model (DMV) may be upgraded to the full featured remote version by simply returning to Trilogy for chip and firmware updates.
As with any Stax compatible energiser Performance is dependent on the quality of the source i.e. CD players analogue output stage, and quality of other manufacturers digital volume controls, but the buyer of the H1 rest assured that Trilogy once again, has redefined the standard by which Stax compatible energisers must be judged by and must be experienced to be believed.

'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.
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
