The 820S is known for its remarkable performance enhancements that are noticeable even when paired with just a single component. Touted by Jeff Dorgay from TONEAudio for its substantial performance upgrade, the 820S is well worth the investment. It uniquely features the capability to power up to two units simultaneously, catering to a diverse range of needs. Designed with versatility in mind, the 820S is engineered to support both digital and analog products, making it a versatile choice for enhancing audio setups. Whether you are looking to upgrade a home audio system or integrate high-performance audio components, the 820S stands out as an adaptable and powerful solution.
Features
Power Supply:
- Transformers: Two custom proprietary toroidal transformers designed for lower magnetic, electrical, and thermal loss, enhancing power transfer and reducing the regulation factor.
- Purpose: One for analog and one for digital power supplies.
Capacitance and Inductance:
- Filters: Two special “pi-type” filters in both analog and digital power supplies after the initial voltage rectification stage.
- Capacitance: 40,000uF total (4 x 10,000 uF)
- Inductance: Dual choke inductance (2x 20mH)
Voltage Regulation:
- Stages: 4 stages of proprietary M-R2S circuits in both analog and digital supplies.
- Design: Fully discrete voltage regulation using a “precision reference” feeding an amplifier comprising multiple ICs and transistors, instead of a single voltage regulation chip.
- Output: Provides pure DC power that is fast, precise, with virtually unmeasurable noise levels and stable voltage.
Circuit Board Design:
- PCB: 4-layer printed circuit boards crafted with pure copper tracings.
- Characteristics: Extremely low impedance, significantly shorter signal paths, and substantially reduced noise levels.
