In designing the Diablo 300, the Gryphon crew had the luxury and privilege of being able to draw heavily on concepts, components and technological breakthroughs that emerged during the evolution of the much lauded Gryphon Pandora preamplifier and Mephisto power amplifier.

The ultra-transparent, fully balanced volume attenuator topology fully exploits the two balanced inputs. Unlike the vast majority of solid state volume controls that typically introduce dozens of resistors in the signal path, the Diablo 300 employs no more than two for any given level setting.

The extreme wideband frequency response of the Diablo 300 extends from 0.5 Hz to 350 kHz and its prodigious 300 Watt (8 Ohms) power output capability represents a significant increase over the original Diablo. The extreme high current capability of the Diablo 300 allows it to double its output to 600 Watts in a 4 Ohm load and deliver a massive 950 Watts into 2 Ohms.

As these numbers confirm, the Gryphon Diablo 300 will remain rock solid when confronted with even the most viciously reactive loudspeaker loads.

Diablo 300 maintains a power reservoir capacity of 68,000 microFarad and employs local active shunt regulators for superior noise suppression compared to the Zener diode regulated low-voltage supplies of the original Diablo.

Because it operates without negative feedback, the Gryphon Diablo 300 avoids both the intrinsic time-delay caused by sending the output signal to the input for a comparator loop and the resulting intermodulation distortion between time-offset signals.

Further highlights include massive, overkill power supplies, high Class A/B bias, state of the art audiophile components throughout, mounted on military specification dual- and four-layer printed circuit boards with virtually no point-to-point wiring.

Diablo 300 utilises new, low-capacitance pre-driver transistors and increased current in the voltage amplification stage for extended bandwidth and increased slew rate. The wire-wound emitter diodes in the original Diablo output stage have been upgraded to non-inductive types.

The power supplies for various amplification stages employ only polypropylene coupling capacitors in parallel with high-grade electrolytic capacitors.

DAC 

This integrated is outfitted with the optional Gryphon DAC PCM/DSD module based on the innovative, award-winning Gryphon Kalliope digital-to- analogue converter. The module adds five digital inputs (USB, balanced AES 115 Ω, optical and dual S/PDIF 75 Ω). USB can process PCM up to 32-bit/384 kHz as well as DSD (Windows OS up to DSD512, Mac OS up to DSD128, Linux OS up to DSD128 DoP).
The remaining digital connections can handle PCM up to 24-bit/192 kHz.

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