Auris II
A reference modular line stage delivering zero-feedback parallel single-ended triode purity.
Key Features
01
Purist 6H30 Triode Gain Topology
Features a high-current, low-impedance parallel single-ended gain layout utilizing four hand-matched 6H30 vacuum tubes to maximize signal propagation linearity.
02
Absolute Zero Feedback Architecture
Operates with 0dB of global or local negative feedback, eliminating internal phase shifts and temporal blurring to preserve organic tone density.
03
Tube Rectified Power Infrastructure
Deploys an advanced tube-regulated power supply with isolated dual chokes to secure total electrical segregation between the sensitive input grids and high-voltage output stages.
04
Dual Grounding & Star Earth System
Incorporates a proprietary central one-point star earth layout alongside a switchable rear dual-ground loop system to reject incoming AC line noise and transformer hash.
05
Switchable Line Output Gain
Provides a user-selectable gain switch on the rear chassis, permitting immediate calibration between 0dB and +6dB for ideal component level integration.
06
Premium Material Architecture
Utilizes a gold-plated industrial-grade PCB layout alongside beryllium-copper spring socket pins, Swiss-made ELMA input selectors, and a custom four-channel volume matrix.
