Precision, Power, and Purity - Trilogy at the Edinburgh Hi-AV Show

31/10/25

We have pleasure in announcing that Trilogy will feature 3 of their amplifiers at this years show.

Trilogy 914 Preamplifier

At the heart of pure performance.

The Trilogy 914 is a fully balanced preamplifier crafted for absolute transparency and musical truth. Designed by Nic Poulson, its refined circuit employs six 6H6 super tubes and twenty-eight sputtered ruthenium relays to preserve every nuance of the signal. Three independent transformers separately power the control, heater, and high-tension stages, while four shunt-regulated supplies maintain absolute silence and stability. With at total of six inputs - 3x RCA 3x balanced and balanced and RCA outputs, and Trilogy firmware that offers extensive user customisation, the 914 combines intuitive control with sublime sonic depth. Impeccably built and effortlessly musical, it belongs at the centre of every reference-grade system.

Trilogy 994 Power Amplifier

Valve purity, solid-state power.

The Trilogy 994 is a monaural hybrid power amplifier that blends the tonal beauty of valves input stages with the control of solid-state design. Delivering 140W into 8 Ohms, it inherits much of the acclaimed 995R’s architecture in a more compact, sculpted form. Its 6H6? valve operates in a grounded-grid configuration driving Trilogy’s distinctive compound output stage, free from negative feedback. Choose between Class A, Class AB, or ecoA operation to suit your mood and system. A massive choke-input power supply anchors its authority. The 994 is both a technical and aesthetic statement - where form, function, and musical emotion converge. Alan Sircom stated in his hi-fi+ review of May 2025 in both performance and build “The Trilogy 914 and 994 (monaural) amplifiers are the best little secret in the audio world.”

Trilogy 921 Amplifier

The art of integration, perfected.

The Trilogy 921 challenges convention by uniting pre and power amplifier performance within a single, uncompromised chassis finished in natural silver or a tactile stealth black. A solid state design - first for Trilogy, a single ultra-linear gain stage feeds a high-bandwidth compound output stage using premium Japanese bipolar devices, ensuring exceptional speed, control, and clarity. Separate rectification and capacitor banks for each channel, powered by independent transformer windings, deliver immaculate current and channel separation. Its stacked internal architecture shortens signal paths, enhancing focus and coherence. With minimal feedback and meticulous build quality, the 921 provides the fluidity and emotional engagement of valve design - a masterful balance of precision. Winner of the Hi-Fi+ 25th Anniversary Editor’s Choice Award and The Ear Editor’s Choice Award 2024, the 921 embodies the pursuit of excellence that has guided Trilogy for over three decades.
