What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- Illustrious performance beyond the 25-watt Enleum AMP-23R, leapfrogging to 100 watts to sanctify more speakers
- Extremist visual finesse and thin-is-in futurism, with design ambitions comparable to 'Apple chic'

- 32-bit software constantly monitors and auto-adapts the power transistor class AB bias for optimal performance without warm-up
Product Considerations
- Associated costs for its hyper styling may not be worth it for everyone
- Operation without visible switches, controls, or a typical display can be perplexing
- Making practical concessions for an ultra-sleek look is a hurdle, viewing the LED display from afar is vague compared to a numerical readout
Comparisons (according to reviewers)
- Versus the Enleum AMP-23R, the AMP-54R scales up output power times four
Takeaway: The Enleum AMP-54R is a visually stunning amplifier with advanced features, aiming for top-tier performance. It's a unique product for those who value aesthetics and innovative design as much as audio quality.

Our take on the brand
The 032 Integrated Amplifier offers a wide variety of connectivity that far exceeds the normal range of integrated amplifiers. A PRE OUT output, for example, allows the connection of a separate power amplifier or the central volume control of different listening zones within a multi-room application. With its mighty 650 VA power supply the 032 Integrated Amplifier effortlessly delivers continuous high current in order to perfectly control even large speakers with low impedance and complex loads. Excellent special resolution and musicality are the hallmarks of the 032.
Product Strengths
- Music is delivered without perturbation, showcasing a 'grip' on the music
- A beautiful sonic palette is present, with a warm, detailed bass and very smooth, detailed highs
- Understated approach to music replay is pure and precise, without coarseness or grain
- Fabulously well made, with impressive build and finish
- Volume control has a hefty, well-damped but very precise feel to it, and the amplifier's on-board software is quick to respond
Product Considerations
- The headphone output is hidden on the rear panel, making it inconvenient to connect
- Large and heavy (around 40kg), requiring sturdy equipment support and assistance when unpacking
- The combination of heatsinks all-round and reflective chrome front panel may not be to all tastes
- Highly transparent sources and speakers are required to get the best performance
Takeaway: The Burmester 032 integrated amplifier sounds exceptional with refined sound and impressive insight. If the system is talented, this amplifier could be a great match.

Incorporating our Pulsus phono stage solidifies our vinyl heritage and with a dedicated mains transformer giving independent power to each channel, your favourite records will sound outstandingly realistic.
Independently powering the Pre and dual mono amplifiers is a phenomenally large mains transformer and capacitor reservoir, delivering an unadulterated sound through the worlds best volume control to your ears. Simply Awesome.
Product Strengths
- Very low noise floor creates a wide open and clear soundstage with excellent space between each musical element
- Delivers subtle intricate details of music, the decays, and the harmonics
- The built-in phono stage—the Pulsus—provides a clear and clean sound, allowing for a more open and see-through soundstage
- The ALPS RK50 volume knob is satisfying to adjust with its stiff—yet smooth—resistance
- The unit is handmade in the UK
Product Considerations
- Limited number of inputs may not be sufficient for all users
- Lacks a remote control, which may be inconvenient for some users
- Awkward access to the underside cartridge adjustment for gain, resistance, and capacitance may be annoying to adjust
- May emphasize upper vocals, which may not be ideal for all types of music, especially at louder volumes
- The mid/upper bass may be a little shy, lacking the solidity, impact, and warmth that some listeners prefer
Comparisons (according to reviewers)
- The NAD M23 has a bolder, stronger, and punchier bass compared to the Sigsum
- The McIntosh sounds more powerful, solid, secure, and full in terms of tone—and bigger overall—compared to the Sigsum
- The Pulsus phono stage sounds clearer and cleaner than the Avid Pellar phono stage, but the Pellar sounds fuller and thicker
Takeaway: The Avid SigSum is a specialized amplifier that is designed for the audiophile who values the preservation of detail, particularly from vinyl playback. It's a great amplifier to highlight the nuances of music, while offering a clean and precise sound.

Our take on the brand
Rhapsody is the pinnacle of our decades of experience in developing State of the art valve amplifiers. The name itself is the expression of our devotion to the Music and the Art. By definition it implicates the profound roots and legacy to the ancient Greek Art of the rhapsodists in performing Epics, to the most modern compositions, where the one-movement work structure of highly contrasted moods, colours and tonality, is expansive and yet unified in structure. The 300B valves are a piece of great audio history that are represented in the Rhapsody in the best and most refined way. The naturalness, the drive, their tonality and rich colour pallets are unmistakable. All of those virtues are combined and moved a step further by Trafomatic dedication into the deep understanding of the cyrcuit. The result is a endlessness adventure in discovering undisclosed hidden places in your favorite recordings.
Product Strengths
- Delivers a 'silky sheen' characteristic of SET designs, which helps to prevent listener fatigue
- Offers a 'room-filling, full-blown' sound, especially with orchestral music
- The Trafomatic Audio Rhapsody presents an 'expressive' and 'real' dynamic range, creating a live musical experience
- Has an innate sense of melody that draws you into the musical mix, and an over-arching sense of sonic accuracy
- Features auto-biasing and toggles for 'Mesh' and 'Solid' 300B tubes, for enthusiasts who wish to try different valves
Product Considerations
- Limited wattage may restrict loudspeaker choices, requiring pairing with high-sensitivity models
- Bass frequencies exhibit higher distortion at lower power outputs
- The amplifier's modest S/N ratio suggests some mild background hiss may be audible
- Bright red chassis is a fixed color scheme, which may not appeal to everyone
- Reviews of the Rhapsody should be judged as very specific amplifier/speaker combos
Takeaway: The Trafomatic Rhapsody is a class act that draws attention to itself purely through its vivid and real sound. It plays music in such a way that one might never want to listen to anything else.
