Trilogy 914
Pre-Amplifier
The audio circuit of the 914 preamplifier benefits from Nic Poulson’s years of experience in audio design, his pursuit of transparency and true fidelity leads to an elegant solution that reflects the passion of the designer.
A truly versatile fully balanced pre amplifier from input to output.
Six inputs, three of them balanced, and three RCA are provided.
There is one balanced and one RCA output per channel.
Signal switching in the 914 is handled by no less than 28 sputtered ruthenium Pickering relays.
Once again, using their favourite high transconductance 6H6П super tube to articulately voice all gain duties.
Six in all feature in this products circuit.
Three separate transformers one for ancillary control electronics, one for the valve’s heaters and one for the high tension supplies minimise interaction and maximise musical return.
The importance of shunt regulated power supplies cannot be overstated and ensures the voltage rail remains silent, since the regulator can sink and source current as dictated by the audio circuit.
The Trilogy 914 boasts no fewer than four such supplies.
Once again the convenience of Trilogy firmware makes the 914 a joy to use, and encourages the owner to dig deeper into the settings.
The control menu is accessed intuitively using the rotary encoder plus enter and escape buttons.
The hierarchy is carefully designed to put all the commonly needed commands close to hand.
Display brightness, customised labels and gain trims for each input, film mode, security bonding, sleep countdown, timed system switch on via TASlink, and remote operation are amongst the many configurable options available to make the 914 truly yours.
The 914 is of rare quality, it offers both supreme flexibility and peerless construction.
Above all, it is the sublime musical performance that will convince you of its rightful place; at the very heart of your system.
Conclusion of Alan Sircoms review
“Good preamplifiers are often the most ‘hair-shirt’ in approach. The Trilogy 914 is a rare exception: a tremendous sounding preamplifier that allows a lot of user control.
But even the 914 pales compared to the 994s, which are some of the best-sounding power amplifiers I have ever heard, irrespective of price.
The combination works exceptionally well, too. I’m usually pretty good at second-guessing the price of a product based on its performance, build, weight and so on.
I’m generally correct within a ±10% margin.
So, here’s a perfectly good £25,000 preamp paired with a pair of £40,000 per channel mono power amps (which sound like £160,000 per channel mono amps with the wind in the right direction)… that happens to be £13,000 and £21500, respectively.
The Trilogy 914 and 994 amplifiers are the best little secret in the audio world.

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.
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.
They at Trilogy Audio Systems do things differently.
