What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

  • Accidental switching of 'On/Off' is possible due to the touch-sensitive bar in the front not being intuitive, so use with care around pets
  • Too powerful for some very sensitive IEMs, potentially resulting in overwhelming sound or audible hiss, though this is not the intended design for the amplifier

Comparisons (according to reviewers)

  • Vs HIFIMAN Susvara, Envy empowers Susvara's natural presentation while giving it all the dynamics and slam needed
  • Vs Cayin HA-300MkII, Envy exhibits more linear mid-to-high frequencies and offers a more transparent sound, while HA-300MkII has a warmer—more engaging midrange
  • Vs AURIS Headonia 2A3, Envy performs at the same level, with technically incredibly strong aspects
  • Vs Octave V 16, Envy completely demolishes the V 16 when it comes to energy, control, timbre, and resolution

Trilogy
H1Energiser

Reviews

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.

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.

Product Strengths

  • Possesses the transparency, resolution, detail retrieval, and coherency of an electrostatic rig combined with the musicality of a single-ended triode amplifier
  • Tone and timbre are natural, beautiful, rich, and edible
  • Exceptional volumetric cube (soundstage) and ability to render depth and width
  • Reveals space via endless microdynamic details, nuance, and spatial cues, creating a 'you-are-there' experience
  • Svelte and aesthetically clean design, available in black or silver, with a minimalist front facade

Product Considerations

  • Sub-bass reach is a limitation; it expertly handles mid and upper bass, and even the initial steps of the deep bass regions remarkably well, though not the deepest bass

Comparisons (according to reviewers)

  • Vs Viva Egoista STX: The Trilogy H1 did not offer the incredible clarity or openness of the Viva Egoista STX, but it was closer in quality than expected

Takeaway: The Trilogy H1 Energizer combines electrostatic capabilities with single-ended triode qualities, resulting in a sublime musical experience. It brings forth music with exceptional detail and a delicious tonality, making it a remarkable first electrostatic product from Trilogy.
