The new Integrated amplifier delivers ten percent more output power than its renowned predecessor, but the 333’s performance extends beyond mere wattage. Incorporating circuit advancements and components from Gryphon’s flagship Apex and Commander Amplifier and Preamplifier, the Diablo 333 benefits from a “trickle-down” effect. Newly developed ultra-fast pre-driver transistors enhance both musicality and measured performance, while the output devices—ten per channel—are the same as those used in Gryphon’s State-of-the-Art Apex. A significantly enhanced power supply, featuring an oversized Holmgren Dual-Mono Transformer and 68,000uF per channel filter capacitance, provides substantial dynamic headroom and contributes to the amplifier's 50.6 kg (112 lb) weight.

The design of the 333 unmistakably reflects Gryphon’s DNA. The triangular display panel with a 4.3” TFT capacitive touch screen mirrors the aesthetic crafted for the Apex and Commander by Gryphon Founder Flemming Rasmussen. Custom-made chassis spikes, developed for Apex, enhance both the mechanical stability and visual harmony of the amplifier. Additionally, bespoke binding posts adorn the rear panel, along with a generous selection of connectors, including dual Subwoofer Outputs, a Tape Loop, and the option to select an XLR or RCA “Unity Gain” Home Theater throughput. The sculpted billet aluminum remote handset from the Commander replaces the previous “Wand” remote supplied with the Diablo 300. A redesigned menu structure offers a more intuitive user interface, while a USB 2.0 socket on the rear panel simplifies firmware upgrades.
