What's unique about the brand

Trilogy Audio is a UK-based hifi brand known for its hybrid amplifier designs that combine valve and solid-state technologies, with their products featuring CNC-milled aluminum construction and microprocessor control for customization. Their amplifiers use virtually feedback-free valve-based amplification and true choke input power supplies, setting them apart from conventional designs in the industry.

What reviewers are saying

We read all the reviews. Here's what reviewers feel most strongly about:

  • Trilogy stands out for its unique hybrid amplifier designs, expertly blending the strengths of both valve and solid-state technologies to achieve a musically fluent sound.
  • The brand's products boast exceptional build quality, characterized by meticulously machined aluminum casework and high-end internal components, reflecting a commitment to both aesthetics and longevity.
  • Trilogy integrates sophisticated, user-friendly control systems with features such as customizable input settings, temperature monitoring, and programmable timers to enhance the overall user experience.

Our favorite reviewer quotes:

  • "Harmonic richness, charm and expressiveness form its very core, yet artfully combined with unrestricted dynamite alike attitude on demand, on-stage grandeur, vividness, effortlessness, readability, inherent sophistication and all above. Put bluntly, such voicing is the full care package indeed and also the very best thing about today's trio." (http://hifiknights.com/reviews/amplifiers/trilogy-915r-995r)
  • "Fully developed, organic, finely contoured and artfully separated shapes sketched by the 995R/915R duo not only felt very much alive, but occupied as equally vibrant space. Stunningly big, served as closely or distantly as repertoire allowed and pleasantly hydrated, it felt utmost coherent, admirably open, substantial, movable and tangible at the same time." (http://hifiknights.com/reviews/amplifiers/trilogy-915r-995r)
  • "All the transparency, resolution, detail retrieval, and coherency of an electrostatic rig—headphone and amplifier (energizer)—and the ease and beauty and profound musicality of a single-ended triode amplifier. If you can work that out in your mind—the tacit, intermingling dualities, the incongruities, the profoundly seductive engagement on offer, then you will have some idea of the Trilogy H1 Energizer and its country." (https://www.audiokeyreviews.com/the-reviews/trilogy-h1-energizer)
  • "The Trilogy H1 was every bit as commanding and musical, natural and prodigiously detailed, but, perhaps, even more gripping, more inherently musical than its brethren. It was as though the music simply took you over." (https://www.audiokeyreviews.com/the-reviews/trilogy-h1-energizer)
  • "The imaging it delivers is also spectacular. Thus far I haven't witnessed anything of quality this high in an amplifier." (http://hifiknights.com/reviews/amplifiers/trilogy-audio-systems-925)

About the brand

Pass Labs Class A amplifiers are celebrated for their distinctive sonic character, delivering a rich, full-bodied sound with a notably lush midrange. They imbue a unique sense of "plumpness" and warmth to the music, an intentional coloration that many enthusiasts find highly engaging. The pure Class A design ensures smooth, beautiful sound but comes with the trade-off of generating significant heat, which can warm up a room.
