Gryphon’s Diablo 333 Dual Mono Integrated Amplifier is a Danish Dragon

Priced from $24,990, the Gryphon Audio Designs Diablo 333 makes its case for best integrated amplifier in the world.

Gryphon Audio Designs does not update its lineup every year and any changes to its flagship products are major design and engineering overhauls. The engineering, connectivity, and sonic changes have to advance the art and make the component unique within a rather competitive category. The Gryphon Audio Designs Diablo 333 integrated amplifier made its global premiere at High END Munich 2023 and is finally set to start shipping on October 31, 2023.

Priced at $24,990 to $37,590 USD depending on optional configuration modules for an internal DAC and phono stage, the Danish behemoth (112 pounds) is one of the pricier integrated amplifiers on the market and is capable of driving any loudspeaker.

Outputting 333 watts per channel (8 ohms) and 666 watts per channel (4 ohms), the Diablo 333 is unlikely to run out of gas with most loudspeakers currently available.

The new Diablo 333 is a cost-no-object replacement for the award-winning Diablo 300, which debuted in 2015. Although its predecessor was highly regarded and the company’s best selling product, Gryphon has found a way to improve upon it by using “trickle-down” technology from its flagship Apex power amplifier and Commander preamplifier.

The Diablo 333 boasts ten percent more output power than its predecessor, while new ultra-fast, low-capacitance pre-driver transistors deliver both enhanced musicality and superior measured performance.

The triangular display panel with 4.3” TFT capacitive touch screen evokes the aesthetic created by Gryphon Founder Flemming Rasmussen for Apex and Commander, as do custom-made chassis spikes which enhance both mechanical integrity and visual harmony. Also developed for Apex, Gryphon’s bespoke binding posts are also found on the 333’s back panel.

Sculpted from a block of 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 can be outfitted with optional Phono and DAC modules which have been completely redesigned for the new amplifier. The PS-3 RIAA 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.

MC load impedance can be set externally with left/right rear panel switches, versus the internal jumpers found on the PS-2S. MC/MM setting is front-panel selectable via the Diablo’s 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.
