Our take on the brand
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.
Our Summary
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.

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.
Our Summary
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.
Our Summary
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.
