The Soulnote A-1 Integrated Amplifier sets new standards for audio performance through its meticulous attention to detail and innovative design.

Meticulously engineered, discrete non-NFB circuits  
To fully leverage the distinctive attributes of SOULNOTE's original perfectly balanced, discrete non-NFB circuits, we meticulously scrutinized every aspect of our amplifiers for potential enhancements. This included the integration of ground plane star wiring, centralization of local non-NFB regulators, establishment of direct coupling pathways, and optimization of drive current tuning, among other refinements. These efforts have resulted in heightened vibrancy and speed, as well as an expanded sound range.  

High-performance, discrete non-NFB power supply  
We have introduced a newly designed bifilar wound, high-capacity toroidal transformer featuring independent positive and negative windings. Additionally, we have reduced impedance by connecting multiple high-voltage, small-capacity filter capacitors in parallel and utilizing a fast recovery rectifier diode. Every detail has been meticulously refined to enhance the power supply, including minimizing current loops by positioning the rectifier diode in close proximity to the power transformer. This optimization further elevates the signal-to-noise ratio and speed.
