Overview

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.


Surpassing the ‘300 was no easy feat; however, thanks to the engineering genius of Gryphon’s Chief Designer, Tom Moeller, the artistic sensibilities of Gryphon Founder Flemming Rasmussen as well as the development of cutting-edge component technologies, Gryphon has authored a new benchmark, better in virtually every respect than its iconic predecessor. A completely reimagined amplifier whose ideal feature set, aesthetic beauty, heirloom build quality and enormous performance envelope establish an unprecedented level of excellence. Gryphon proudly introduces Diablo 333: The World’s Finest Integrated Amplifier.


The Drive

Our new Integrated boasts ten percent more output power than its legendary predecessor, but there’s more to 333’s performance than wattage alone. Circuit advancements and parts from the new Apex and Commander, Gryphon’s flagship Amplifier and Preamplifier, have “Trickled-Down” to the Diablo 333. New, ultra-fast, pre-driver transistors deliver both enhanced musicality and superior measured performance while output devices—ten per channel—are identical to those found in our State-of-the-Art Apex. A massively augmented power supply distinguished by an oversized Holmgren Dual-Mono Transformer and 68,000uF per channel filter capacitance provide enormous dynamic headroom and explain the 333’s 50.6 Kg (112 lb) mass.


One look at the 333 and the Gryphon DNA is obvious: the triangular display panel with 4.3” TFT capacitive touch screen evokes the aesthetic created for Apex and Commander by Gryphon Founder Flemming Rasmussen, as do custom-made chassis spikes which enhance both mechanical stability and visual harmony. Also developed for Apex, Gryphon’s bespoke binding posts adorn the 333’s back panel, which also reveals a generous connector complement, including dual Subwoofer Outputs, a Tape Loop and the ability to select an XLR or RCA “Unity Gain” Home Theater throughput. Sculpted from billet aluminum, the remote handset from Commander replaces the “Wand” remote supplied with Diablo 300. A new, more intuitive menu structure enhances the user interface while a USB 2.0 socket on Diablo’s rear panel simplifies firmware upgrades.


As with the Diablo 300, the 333’s capabilities can be expanded with optional Phono and DAC modules. As befits an all-new amplifier, these modules have also been completely redesigned and their performance elevated. The PS-3 Phono Module features True Dual Mono Class A-coupled topology from input to output, with no global negative feedback and discrete balanced circuitry featuring matched transistor arrays. Gold-plated Neutrik XLR balanced input sockets replace the RCA sockets utilized in the previous generation PS-2S. MC load impedance can be set externally with left/right rear panel switches, versus the less convenient internal jumpers found on the PS-2S . MC/MM setting is front-panel selectable via the Diablo 333 menu. Gryphon’s new DAC-3 D/A MODULE incorporates the latest High-Performance Sabre DAC: the ES9039PRO. Seven user-selectable PCM digital roll-off filters are included, as are a full assortment of USB, AES/EBU, BNC and TOSLINK inputs. The 333’s USB input is compatible with all current Digital Audio Formats.


A New Icon

For music lovers fortunate enough to own a Diablo 300—as well as those of you who have dreamed of owning one—rest assured: the ‘300 remains one of the finest Integrated Amplifiers available, still outperforming newer and more expensive competitors. And yet, purists who quest for the best will find Diablo 333 superior in virtually every aspect of performance, connectivity and parts specification.


Every detail of its legendary predecessor has been scrutinized and, wherever possible, improved; as a result, The 333 now represents the pinnacle of Integrated Amplifier technology.


Diablo 333: the new definition of perfection.

Gryphon Audio Diablo 333 — endgame integrated power with surgical finesse

The Diablo 333 pairs colossal headroom with startling refinement: a 333Wpc dual-mono design that reviewers call an endgame integrated amplifier. Fidelity Magazine and HomeTheaterHifi note its mixture of thunderous, tightly controlled bass and extremely low noise floor, while The Absolute Sound highlights its resolution and musicality. The Diablo builds vast, holographic soundstages with pinpoint imaging and micro-detail retrieval, yet retains a natural midrange and clean, airy treble. Built like an heirloom—massive Holmgren transformer, custom binding posts, responsive touchscreen and modular DAC/phono slots—the 333 suits large rooms and full‑range, tonally balanced loudspeakers. For listeners seeking a single-box solution that can replace separates, the Diablo 333 delivers world-class dynamics, control and expandability that justify its flagship intent.

The Absolute Sound

"It is a dignified monster, a devil in a tuxedo, a beast that can drive the Nürburgring without ever spilling your martini."

Pros

  • Extraordinary raw power and dynamic control—can drive extremely demanding speakers without strain, delivering tight, explosive transients.
  • Outstanding resolution and imaging—creates a deep, holographic soundstage that reveals micro-detail and realistic instrument placement.
  • Heirloom-level build and flexible feature set—robust power supply, custom terminals, responsive touchscreen and upgradeable DAC/phono modules.
  • Authoritative, well-controlled low end—deep, fast and tuneful bass that remains clean even at high levels.

&

Cons

  • Very large and heavy—50.6 kg / ~112 lb makes placement, rack fit and handling nontrivial.
  • Premium price and niche positioning—top-tier cost limits accessibility despite strong value-for-performance within its class.
  • Requires careful system matching—demands high-quality sources and speakers to realize its full potential.
  • Phono module uses balanced XLR inputs only—may complicate hookup for users with single‑ended tonearm wiring or legacy cabling.

Sound Quality

Dynamics

96/100

With 333Wpc (666W/4ohm) and reviewers noting it as 'the most dynamic and controlled integrated amplifier' and 'effortless' with huge headroom, the Diablo delivers exceptional transient slam, control and scale (SoundStage Solo, HomeTheaterHifi, Tracking Angle). Multiple reviewers emphasized it never runs out of steam and handles massive dynamic swings with delicacy (TAS, Fidelity).

Soundstage Imaging

95/100

Reviewers praised a large, deep, holographic soundstage with precise, pinpoint images and excellent separation (Fidelity, SoundStage Solo, HiFi News). Several accounts describe an enormous spatial depth and strongly defined instrument placement, making the amp particularly strong for imaging and three-dimensional presentation.

Build Quality

96/100

The Diablo 333 is repeatedly described as massively built and heirloom-quality, with large heatsinks, bespoke binding posts, dual-mono transformers and heavy filter capacitance; manufacturing in Denmark and flawless fit-and-finish were noted across reviews (SoundStage Solo, Best of High End, Pursuit Perfect System). Thermal management and high-end connectorry were specifically praised.

Features Connectivity

95/100

The unit offers strong one-box flexibility: optional high-quality DAC-3 (ES9039PRO) and PS-3 phono modules (dual-mono, extensive loading), two balanced and two single-ended inputs, tape loop, dual subwoofer outputs, two pairs of speaker terminals, touchscreen UI and home-theater 'unity gain' throughput. Those expandability and digital/phono options push this well into the fully-featured category.

Value for Money

95/100

Multiple reviewers explicitly praised the Diablo 333's value relative to its performance: TAS called it 'a no-brainer' for a Golden Ear, HomeTheaterHifi and FutureAudiophile called it a 'real value' and 'value-oriented purchase', and several reviews noted it can replace multi-box separates — strong, repeated endorsements that justify a top-tier value rating for its market segment.
