Select products
Evolution Phono One
- Positioning: The entry-level model aimed at basic vinyl playback setups.
- Description: Uses an OP AMP design with separate MM and MC inputs and selectable impedance to ensure low noise performance. Compared to tube-based or high-power models in the lineup, its straightforward design suits smaller rooms and modest budgets with minimal functionality needs.
Tara 30A
- Positioning: A balanced tube preamplifier crafted for refined audio reproduction at a moderate price point.
- Description: Features Emission Labs 30A tubes, dynamic balance adjustment and an extremely low output impedance for precise channel matching. Compared to the entry-level Evolution Phono One, it adds tube warmth and detailed control, though it remains less complex than higher-powered amplifiers like EOS+ or flagship systems.
EOS+ Power Amp
- Positioning: A dual mono power amplifier engineered to deliver high power for demanding speaker systems.
- Description: Uses push-pull design with KT150 tubes and tuned negative as well as cathode feedback, resulting in well-controlled bass and a dynamic response. In contrast to preamplifiers like Tara 30A, it provides substantial power output.
Elysium
- Positioning: A flagship mono-block power amplifier built with state of the art tube circuitry for uncompromised sound quality.
- Description: Uses pure Class A circuits with Eimac 250TL output tubes and a unique direct-coupled transformer setup to extract every subtle detail. Compared to the EOS+ Power Amp which focuses on power output, it offers a more refined sonic character.
Rhapsody
- Positioning: An integrated amplifier representing the highest achievement in valve amplifier design.
- Description: Features 300B valves in a parallel single-ended Class A configuration to produce natural tonality and rich coloration with unified performance. Compared to standalone preamplifiers or power amplifiers, its all-in-one design delivers exceptional technical sophistication.

Enleum was launched as a new brand with the AMP-23R. While our legacy AMP-13R had already been praised all around the world for its performance and unique design, we pushed the boundaries to create the AMP-23R with a new circuit that truly enhances the existing performance. We have drastically improved the PCB circuit board design, chosen new internal components and upgraded our JET2 Bias design. And the reviews and awards are unanimous. The AMP-23R's physical size and footprint may be compact, but with the all new chassis and thermal heatsink design, we've launched a product that's fit for the next generation reference compact amplifier. The unique design is the DNA of our new Enleum Brand and was already awarded the Red Dot Award: Product Design 2021 and iF Design Gold Award 2022. The AMP-23R proudly showcases Enleum's expertise in technology and design.

Our take on the brand
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.
