Elevate your audio experience with the Denafrips Hades 15Th preamplifier, a masterpiece born from an uncompromising dedication to audio perfection. Designed for discerning audiophiles, the Hades is the pinnacle of technical precision and sonic sophistication.
Developed and manufactured with precision and care, the Hades features a fully discrete, fully balanced pure Class A line stage.
Its 60-step attenuator, controlled by a microprocessor and equipped with precision-matched resistors, ensures perfect channel balance and extremely low distortion, measured at just 0.00023%. The result is sound of incredible purity, clarity, and precision.
All of the Hades' components are housed in a sturdy, modern aluminum chassis. It also features a front panel display to show the selected volume level.
Key Features:


The gain is achieved using a network of resistors and balanced transistors.
Relay with 60 steps controlled by microcontroller (CPU).
This is not a universal transformer, but one specially designed for the Class A architecture and high-precision components of this preamplifier. This design prevents performance losses caused by “excessive or insufficient power supply,” ensuring that every unit of electrical energy is used precisely for signal amplification.
A set of custom-made low-noise linear capacitors suppresses ripple interference from the power supply source; combined with a linear power supply architecture, it reduces power supply noise to an extremely low level.
