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.

- 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

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.

Our take on the brand
Driven by sound quality and our uncompromising approach to offer the best in class, the sensational SIGSUM Integrated was conceived.Our single chassis amplifier offers unparalleled performance for those that desire less clutter or with demands on their dwellings.
Musical Obsession
SIGSUM swiftly dispels any preconception that single chassis amplifiers limit performance. Condensing our reference designs into class leading premium products is our forte and its clarity and power will expose a musical revelation.
Lurking behind our trademark embellished front panel we have distilled, condensed and shoe-horned our reference technology into a singular monument to convey true musicality.

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
Product Strengths
- Exceedingly clean, detailed, linear, and transparent sound is delivered without adding color, pushing headphones to their limits
- Exceptional build quality, with hand-selected, tested, and matched components ensuring optimal performance
- High impedance output provides stronger performance with lower sensitivity headphones than its raw wattage number would suggest
- Razor sharp imaging and unparalleled instrument separation delivers every nuance in the music
Product Considerations
- Rocker power switch looks and feels cheap, disrupting the aesthetic
- Soundstage isn't the widest and may sound a bit up close and personal
- Does not give the same punch or slam as some other amps, lacking those massive capacitors found in other amps with reserve power
- High output impedance means some highly sensitive headphones and most IEMs will experience some level of change to the frequency response
Comparisons (according to reviewers)
- Compared to the Zale hm1, the Mascobo 465 is enhanced in terms of image and detail
- Compared to the Cayin Soul 170HA, the MASS-kobo's sound is more pristine and transparent, while the Soul offers a perceived warmth and elevated body, the Soul also cannot keep up with the dynamics and immediacy of MASS-kobo
Takeaway: The Mascobo 465 is a high-end headphone amplifier that is meticulously built and provides exceptional detail and clarity to the sound. It's a great choice for audiophiles seeking a top-tier listening experience with high-end headphones.

Video review
Our take on the brand
Our Summary
Product Strengths
- Strikingly clean and detailed presentation
- Plenty of power to drive difficult speaker loads, with close to doubling of output as impedance halves
- Exceptionally well made with reassuringly solid casework and precise controls
- Adaptable phono stage offering easy switching between MM and two MC options
- Wonderfully unforced and natural performance at any listening level
Product Considerations
- Needs care in system matching to avoid a slight lack of richness/body, tone controls can help
- No impedance adjustment on the phono stage
- Very large physically, which may pose placement issues
- Plastic battery cover on the metal remote is a misstep in overall exemplary build
Comparisons (according to reviewers)
- Compared to Moon by Simaudio 641 or McIntosh MA8950, the L-509Z has a slight lack of richness and body to the sound
- Compared to McIntosh MA8950, the L-509Z requires separate source equipment—unlike the all-in-one MA8950
- Compared to Vitus RI 101 Mk II, the Vitus is a bit more dynamic and slightly brighter—but costs significantly more without a sound difference worth the price
