Denafrips Hestia 15TH Discrete Balanced Preamplifier Pure Class A Black
With the Hestia 15Th, Denafrips presents a balanced preamplifier based on 100% discrete components operating in pure class A to deliver unprecedented sound quality. Its 60-step attenuator, controlled by a microprocessor and equipped with precision-adjusted resistors, guarantees perfect channel balance and an incredibly low harmonic distortion level of just 0.00023%, ensuring the clearest possible sound reproduction.
Denafrips Hestia 15TH: Smooth and precise volume attenuation
A microprocessor-controlled 60-step relay attenuator with precision-matched resistors ensures near-perfect channel balance and ultra-low distortion (THD 0.000230%). Volume transitions remain smooth, preserving natural dynamics and an immersive, fluid soundstage.
The structure of the Denafrips Hestia 15TH
#1 Discrete Class A gain
The gain is achieved using a network of balanced transistors and resistors.
#2 Attenuator
Relay with 60 steps controlled by microcontroller (UC).
#3 Proprietary Type-O Transformer
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.
#4 Low-noise linear power supply capacitors
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.
Denafrips Hestia 15Th overview
With its two balanced inputs and one balanced output, the Hestia can be integrated seamlessly into any audio setup, whether it's a professional studio or an audiophile system. Its adaptive nature and compatibility ensure smooth integration into your existing setup, improving overall performance and delivering an incredibly expansive and immersive soundstage.
