Our Summary
Product Strengths
- Exceptional build quality with a blend of expertly crafted wood and metal, creating a visually striking and durable statement piece
- Dynamic, rich, and effortless sound with excellent detail, texture, and the right amount of tube magic
- Powerful output capable of driving demanding headphones while maintaining clarity and control
- Versatile performance with a variety of headphones (dynamic and planar) due to its output transformer design, often improving sound for warm or neutral headphones
- Value added by its ability to be used as a pre-amplifier in a stereo system
Product Considerations
- Large size and weight (around 15kg) require ample desk space and sturdy furniture
- Generates heat, which could be a concern in warmer environments without adequate ventilation
- 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
- Vs Ferrum OOR, Envy is more powerful sounding, while also being more detailed with better tonality
Takeaway:
The Felix Audio Envy is a high-end headphone amplifier for audio enthusiasts who want the best quality sound to bring out the magic in their favorite headphones. Its stunning design and versatile performance make it a worthwhile addition to any serious audiophile setup.

Our take on the brand
Our Summary
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.

Our take on the brand
Our Summary
Product Strengths
- Improves the performance of headphones, making them sound better
- Images become larger and more distinctly tactile
- Delivers credibility and immersivity, putting headphones into the same ballpark as a good stereo
- Elegant and compact design
- Considered by some to represent the pinnacle of headphone amplification in design and execution
- Placement of RCA's are so close that any high-end RCA cable that has any kind of larger jack assembly will simply not plug in over-and-under into the same-numbered set

- Least apparent power
- Balanced outputs were not included in the original design
Comparisons (according to reviewers)
- Vs HeadAmp GSX Mark II—the E.A.R. has better tone/timbre, imaging, and stereotypical tube benefits to soundstage; HeadAmp has 'blackest' backgrounds, with deepest apparent reach to the bass
- Vs Cavalli Audio Liquid Gold—the E.A.R. has better tone/timbre, imaging, and stereotypical tube benefits to soundstage; Cavalli has widest/tallest sound stage, with best specificity of placement
Takeaway: The EAR HP4 headphone amplifier is a top-tier product with elegant design that elevates the listening experience by improving headphone performance and creating immersive sound. It is an amplifier that inspires listening and immersion in music.
