Our take on the brand
The IN400 EVO is an integrated amp-preamp with high musical capacity. The concept is based on technical and aesthetic choices dedicated to optimal musicality. Mechanically, the chassis is made of 2 mm steel, and the front face is 10 mm aluminium, brushed, micro-blasted, and anodized, with high-precision engraving. The side heatsinks are machined from solid aluminium blocks to absorb mechanical vibrations and ensure perfect heat dissipation.
Our Summary
Product Strengths
- More current than the IN300, thanks to a massive power supply and 16 output devices
- Overall architecture and quality is well above what one normally gets at this price
- Sounds cleaner than the IN300
- Instrument separation is excellent, and it's all presented in a vast soundstage in terms of width as well as in terms of depth
- Has the ability to drive pretty much any speaker on the market
Product Considerations
- The overall tonality still sits on the warm side of neutral
- Leading edges of notes remain softened slightly, as does a touch of bloom to the bass
- Optional DAC and phono boards are not included as standard
Comparisons (according to reviewers)
- Vs Hegel H190: Comfortably outshines it in performance
- Vs Hegel H400: In terms of overall resolution, there isn't much to choose between the IN400 EVO and the H400
Takeaway: The IN400 Evolution provides excellent sound quality and drives speakers well, making it a great choice for audiophiles. It offers excellent value for the price and may outperform separate pre-power amplifier systems.

Our take on the brand
.png){kind=logo}
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 Summary
Product Strengths
- Addictive sound signature, unlike any other amp, with otherworldly instrument and voice reproduction
- Delivers serious magic with Fleetwood Deville and Klipsch Heritage speakers, revealing obscure details and creating a massive soundstage
- Dynamics for days
- Combines the qualities of a nice SET amp without the downsides, like noise or tube replacement
- Exceptional build quality and design with high-quality parts
- Only has two RCA inputs, no XLR balanced connections
Product Considerations
- Heavy speaker cables can cause the amp to tilt
- The volume dial functions as a gain dial, which may be different than what some users are accustomed to
- May not be suitable for hard-to-drive speakers in the 85db range that dip into 2–4 ohms
Comparisons (according to reviewers)
- The AMP23R offers more texture, layering, mid-bass, and vocal presence than Nagra INT
- The AMP23R is more organic, ethereal, and dynamic than Kinki Studio EXM1
- It sounds better than the Vinnie Rossi L2iSE, so long as the speakers are easy to drive
- The Enleum has more delicacy and finesse than Pass Labs and Cary Audio
- The AMP23R stacks up with the finest gear such as ampsandsound Bryce monoblocks
- Pass Labs First Watt SIT-3 offers a bit more organic, warmer presentation
Takeaway: The Enleum AMP-23R is a small but mighty integrated amplifier with a unique and addictive sound signature, and it is built with high-quality components. It's a great choice for those with sensitive speakers looking for a reference-quality system in a compact package.

Our take on the brand
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

Our take on the brand
Our Summary
Product Strengths
- The M23's build quality feels solid and elegant, with impressive small design details
- The sound is striking in its purity and clarity
- It offers up to three levels of gain, switchable on the back panel, to best fit the system
- It provides a clear sound without sounding hard
- It features Purifi Eigentakt Class D amplification, which provides virtually unmeasurable distortion levels
Product Considerations
- The bass is clean but may be perceived as a little on the cool side and not as 'wompy-sounding'
- The M23 is not a forgiving amplifier that makes everything sound sweet and wonderful—it's not for those seeking a soft and mellow sound
- Bridging with speakers below 5 or 6 ohms is not recommended, as the amp will current limit and potentially shut down
- The reviewer found ergonomical challenges using fancy speaker cables in bridged mode due to wide terminal spacing
- The capacitive touch power button can accidentally trigger
Comparisons (according to reviewers)
- Vs Bel Canto C6i: The M23 offered a layer of refinement and better reproduction of the recording space
- Vs Pass XA25: The M23 had more transparent sound and detail, especially in the treble and upper mids, but lacked the organic quality of the XA25
- Vs HiFi Rose RS 520: The M23 sounded cleaner and had better separation/depth, HiFi Rose seemed to have an EQ built-in, emphasizing midrange and bass
- Vs NAD C298: The M23 is more neutral, deals with decay more naturally, and has better casework, making it look high-end
- Vs Anthem M1 monoblock amplifiers: The M23 was slightly more transparent throughout the entire frequency range
