Overview

The concept of an integrated amplifier that embodies the same ethos, musical and sonic qualities as Gryphon Audio Designs’ most esoteric offerings, but at a fraction of the cost, is clearly an attractive proposition and through the single-minded dedication of the Gryphon team, the integrated amplifier has come of age as a serious, respected High End component, bringing legendary Gryphon performance and styling to a new level of affordable cost and ease of use.


As far back as April, 2009, Gryphon introduced the original Atilla, building on the brand’s impressive reputation as a pioneer in the design of unapologetic integrated amplifiers that can stand their ground against the competition’s finest separate components.


French Haute Fidelité magazine called it a “Best Buy.” Australian Hi-Fi magazine placed it “Easily up there with the very best” and UK magazine Hi-Fi Choice simply called the Gryphon Atilla “one of the very finest integrated amplifiers available.”


In continuous production until 2016, the Atilla had a long run that is exceptional in High End audio. (Sadly, longevity is generally an overlooked and seriously undervalued attribute.)
In the interim period, Gryphon has made great advances in the critical fields of circuit topology and parts design and selection with the evolution of the state of the art, cost no object Pandora preamplifier and Mephisto power amplifier.


Now, drawing heavily on our experience with these uncompromising, reference level components, Gryphon Audio Designs proudly presents the next generation Atilla, the Gryphon Diablo 120.


Gryphon Diablo 120 exudes timeless elegance and beauty, informed by the unique vision of Gryphon founder and CEO Flemming E. Rasmussen.


Integrated Greatness

The understated styling and forceful lines of the satin black, brushed aluminium chassis and gleaming black acrylic faceplate represent a superb level of fit and finish, exceptional audio finesse and a sense of unlimited power all on a single chassis.


The casework, consisting of interlocking blocks of flawless acrylic and deeply brushed and anodized aluminium, is true to the acclaimed Gryphon house style, a complex construct of contrasting angles and planes that is both reassuringly intricate and impressively solid.


Built entirely at Gryphon’s Danish research and development and manufacturing facility, the Diablo 120 inherits the dual-mono circuitry, ultra-short signal path, heavily gold-plated printed circuit boards, minimal internal wiring, high-quality gold-plated and PTFE-insulated sockets and proprietary binding posts employed in our flagship models. Only the finest audiophile grade components have been selected based on strenuous, extended auditioning for sound quality, thermal stability and long-term reliability.


The custom made 1,300 VA transformer adds substantial heft with discrete secondary windings for left and right channels. Each channel is fed by its own 60,000 µF capacitor bank.


With two pairs of Sanken transistors, Diablo 120 can easily drive difficult loudspeaker loads without the faintest hint of strain.


The Diablo 120 circuit employs zero global negative feedback and a unique microprocessor controlled passive attenuator for the most transparent volume control ever conceived. Regardless of the selected level, the 46-step relay attenuator places maximum six resistors in the signal path for ultimate sonic purity.


The Diablo 120 offers one balanced and four single-ended inputs, a comprehensive menu of configuration options (four levels of display brightness, user-defined start and maximum volume settings, individual source labelling with eight-character names and a dedicated and electrically isolated A/V bypass function for uncompromising integration with a multi-channel audio system.


Options – Digital or Analogue

At the time of original purchase or as the need arises at a later date, Gryphon Diablo 120 can be fitted with a specially designed Gryphon DAC PCM/DSD module based on the innovative, award-winning Gryphon Kalliope digital-to- analogue converter.


The module adds four digital inputs (USB, balanced AES/EBU 115 Ω, TOSLink optical and BNC S/PDIF 75 Ω). Via USB, the Diablo 120 DAC module can process PCM up to 32-bit/384 kHz as well as DSD (on Windows OS up to DSD512, on Mac OS up to DSD128, on Linux OS up to DSD128 DoP); via BNC S/PDIF and AES/EBU inputs up to192 kHz/32-bit PCM and via TOSLink up to 96 kHz/24-bit PCM. Format compatibility of the various inputs is subject to change without notice.


This future-proof digital module is ready for any current or foreseeable high resolution digital format.


In the finest Gryphon tradition, the Diablo 120 also offers the alternative of an exceptional MM/MC phonostage for the dedicated enthusiasts who continue to enjoy the musical treasures etched in the grooves of the long-playing, black vinyl disc.


Gryphon Diablo 120 conveys music with unusual poise and exceptional subtlety and definition. Lightning reflexes combine with harmonic richness, articulation and refinement to create a lush whole that is very comfortable to listen to over extended periods even at realistic levels.


Gryphon Diablo 120 offers a unique level of musical enthusiasm and energy that will satisfy and delight for many years to come.

Gryphon Audio Diablo 120 — reference-class control in a compact integrated

The Diablo 120 pairs muscular Class-AB current delivery with an unexpectedly quiet, highly resolving presentation, making it a standout for listeners who want both power and finesse. Reviewers from Thomas Richter, Uday Reddy and Edgar Kramer highlight its deep, well-controlled bass, natural midrange weight and a smooth, non-fatiguing treble that creates an expansive soundstage. The dual-mono layout, massive power supply and meticulous grounding underpin exceptional dynamics and imaging, while the optional DAC or phono modules extend connectivity. Ideal for demanding speakers and serious listeners seeking a musical yet authoritative amplifier, the Diablo 120 is built like a tank and presents a reference-quality performance that many reviewers judged worthy of long-term ownership.

SoundStage! Australia

"The Diablo 120 is a categorically exceptional performer that just plays music in a way that motivates involvement and sweeps you into pure enjoyment, inhibiting dissection and analysis."

Pros

  • Extremely low noise floor and resolving detail that reveals subtle recording cues and depth.
  • High-current Class-AB design with commanding dynamics and speaker control up to very low impedances.
  • Top-tier build and engineering — dual-mono architecture, substantial transformer/capacitance and precise grounding for long-term stability.
  • Flexible, high-performance optional modules (DAC or phono) and a refined 46-step relay volume attenuator offer modern connectivity and excellent onboard digital performance.

&

Cons

  • Modular limitation — you cannot fit both the DAC and the phono module simultaneously, so buyers must choose one path.
  • Positioned in the premium segment; its cost and ‘entry-level for Gryphon’ status mean a significant investment compared with mainstream integrateds.

Dynamics

92/100

Class-AB dual-mono design with very high current capability (120W/8Ω, 240W/4Ω, 440W/2Ω) and a large power supply (60,000 µF per channel, 1300VA transformer noted) delivers authoritative, effortless dynamics per reviewers. Multiple reviewers noted it "does not raise a bead of sweat," provides "spectacular power and transient attack," and retains control at high levels—supporting an excellent dynamics score in line with Class-AB high-power expectations.

Soundstage Imaging

93/100

Reviewers repeatedly praised separation, depth and an expansive soundfield: SoundStage Australia noted 'massive soundfield' and exemplary instrument separation, SoundStage (Uday Reddy) reported unexpectedly deep, realistic staging and precise imaging, and Fidelity credited it with matching top transistor performance emotionally. The amp's silence and low noise floor further enhance perceived depth and imaging precision.

Build Quality

92/100

Consistent reports of tank-like construction, dual-mono architecture, massive transformers and an imposing power supply underpin a high build-quality score. Reviewers highlighted superb connector quality, short signal paths, meticulous grounding and thermal stability, and a Bauhaus-quality fit-and-finish—all indicating top-tier mechanical and electrical engineering.

Features Connectivity

95/100

Baseline capability is extended by high-value options: a high-quality built-in DAC module (multiple reviewers noted its very high performance and DSD512/PCM support and multiple digital inputs: USB, coax, AES/EBU, optical), an optional phono stage supporting MM and MC, balanced I/O implied by specs/reviews, and a 46-step relay attenuator. Those features place it among fully featured integrateds (maxed at the schema cap).

Value for Money

90/100

Price points cited (AU$16,395; ~£9450 noted) position the Diablo 120 in a premium segment, but reviewers consistently judged the product's performance to justify the price—Fidelity called it 'lives up to the quality its high price suggests' and a 'valid reference product,' while Pursuit called it 'entry level for Gryphon (far from entry level in general).' Reviewers therefore describe a justified premium rather than bargain pricing.
