  • The IR receiver and Wi-Fi/Bluetooth antenna are external 'appendages'

Comparisons (according to reviewers)

  • The NAD M33 is more expensive, but has similar power output
  • The HiFi Rose RS520 has significantly more power output, which is a difficult value proposition for many audio enthusiasts
  • Similar features to the Cambridge Audio EVO 150, but the HiFi Rose RS520 has a touchscreen and more power

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.

Our summary

Product Strengths

  • Unique and eye-catching 'steampunk-inspired' industrial design stands out from typical amplifiers and could be considered a work of art
  • Offers a versatile feature set, including a customizable phono stage (MM/MC), bass and treble tone controls, and a defeatable active crossover for bi-amping
  • Delivers a transparent, detailed, and generally smooth sound, described as not sterile, analytical, or dry
  • Multiple amplifier configurations are available, including BTL mode for increased power (400Wpc), accommodating various speaker setups
  • Uses GaN FETs which the manufacturer claims improve sound relative to traditional Class D amplifier designs

Product Considerations

  • The 'Class D' or 'Class AD' amplifier topology might be a concern for some audiophiles who prefer Class A or AB amplifiers and associate them with better sound
  • Some reviewers indicate a preference for the sound of Class A/B amplifiers over the RA180, particularly in bass weight
  • The remote control is IR-based and requires a separate receiver 'nubbin' to be plugged in
  • A small audible noise floor was practically non-existent in "normal" mode, but heard with some speakers in BTL mode

Comparisons (according to reviewers)

  • The Michi X3 is preferred overall, though the RA180 has superior build quality and phono stage, and the X3 also has more bass weight
  • The RA180's midrange and treble performance is compared favorably to the NAD M33
  • The McIntosh 7200 has true Class AB topology compared to HiFi Rose, though the HiFi Rose is preferred in smaller stature and industrial design
  • The RA180 bests the Pass Labs XA 60.8 and XP-22 in low-volume late-night listening
  • The Enleum AMP 23R had lit up treble, but the RA180's treble was forward—but not bright—energy

Takeaway: The HiFi Rose RA180 is a unique and powerful amplifier that sounds great and offers many ways to set it up to get the best sound. It is a showpiece that is sure to spark conversation.

Reviews

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.

Enleum is a hifi brand known for its compact yet powerful amplifiers, particularly the AMP-23R, which delivers performance comparable to much larger systems through its unique gain control system and zero negative feedback circuits.

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.

Reviews
Feliks Audio is a Polish brand that handcrafts tube amplifiers, including their flagship Envy model which features single-crystal copper wiring and 300B tubes known for their linearity and low distortion. Their amplifiers stand out for their ability to drive both high-impedance dynamic and planar magnetic headphones, which is uncommon among tube amplifiers, while maintaining a low noise floor and delivering natural, warm sound.
Check Amazon
Expand Details

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.

Released
2022
Building on NAD's long tradition of identifying and developing cutting-edge amplification technology, the M23 HybridDigital Stereo Power Amplifier features Purifi Audio's Eigentakt™ design, a once-in-a-decade innovation that virtually eliminates harmonic and intermodulation distortion. Noise is inaudible, for a completely black background and exquisite micro-detail. Conservatively rated at 2x200W continuous into 8 ohms and 2x380W into 4 ohms, the M23 can deliver live performance levels through any loudspeaker.
Check Amazon
NAD Electronics pioneered affordable hifi equipment by focusing on essential features for good sound, with their classic NAD 3020 becoming the best-selling hifi amplifier in history. Their Masters Series features DirectDigital technology, the world's first closed-loop digital amplification that corrects output every 10 nanoseconds.
Expand Details

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
  • Vs Bryston 4B 3: The Bryston had more grunt but the M23 is more neutral

Takeaway: The NAD M23 is a powerful and precise amplifier that delivers clean and clear sound, making it a great choice for audiophiles who want to hear their music as accurately as possible. It is especially well-suited for those looking to build a high-end system around a quality preamp or DAC.
