What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

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.

Gryphon
Diablo 333

/
9
Reviews

Integrated amplifiers have become the essential audio component, distilling sources, amp, preamp and interconnects into a single chassis. And since 2015, connoisseurs have revered the Gryphon Diablo 300 as the finest integrated amplifier ever produced and a genuine “Object of Desire.” Unanimously praised by critics and with thousands sold, it became High End Audio’s most coveted “Ultra-Luxe” integrated.

Gryphon is one of the most respected high-end amplifier brands in the world. Its bass grip is phenomenal, thanks to an unusually high level of capacitance, which keeps everything tight and controlled, even with demanding speakers. Gryphon is also known for its bold, brutalist design—a look that a lot of people love. You’ll find their gear all over Europe and Asia, and the Diablo 333 is often considered an ‘endgame’ amp by those chasing the very best sound and aesthetics.

Product Strengths

  • Exceptional bass control, power, speed, and definition provides a bedrock foundation for the music
  • Wide and deep soundstage with precise imaging
  • Dead-neutral tonal balance with grain-free clarity, effortless speed, and precision
  • Life-like dynamic expression and detail resolution, sounding exquisitely lifelike
  • Lively, energetic sound combined with pleasing harmonics, warmth, and a kind of lusciousness achieves a nice balance

Product Considerations

  • The binding posts are located low on the rear panel, which might be problematic for some installations
  • It gets hot, requiring adequate ventilation
  • It's a heavy unit, making it difficult to move and set up
  • The cost is very high, making it exclusive-level hifi
  • The speaker spiked feet can make it difficult to position the amplifier

Comparisons (according to reviewers)

  • Vs Diablo 300, the Diablo 333 gives more music and musical information, developing the soundstage with harmonic information, knitting all the individual parts together; the music becomes less about individual things and more about the whole
  • Strong resemblance to the Apex Commander combination, but at a fraction of the cost
  • While the Antileon digs deeper and presents a fuller presentation across the low frequencies, the Diablo 333 slams harder and slightly tighter

Takeaway: The Gryphon Diablo 333 is a powerhouse integrated amplifier that combines exceptional power and control with refined sound and detailed musicality making it one of the very best amplifiers, be it integrated or not. Its versatility and musical soul make it a solid choice for anyone looking for an end-game component.

Reviews

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.

  • 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.

Expand Details

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.

4
Reviews

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.

Trafomatic Audio is unique for crafting its own transformers in-house, which gives them complete control over their amplifiers' sound quality. The brand stands out for using uncommon materials like Panzerholz (hyper-compressed plywood) for resonance control and rare tube types like the Elmac 250TL direct heated triode power tube in their designs.

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.
