Master Series
Master Server｜Master Streamer
Return to the Essence of Digital Music
Concept
In the field of digital audio, most products continue to increase computing power and expand functionality.
Telos returns to a fundamental question:
Why does sound become distorted?
The answer is simple — not insufficient processing, but excessive interference.
The Master Series is built on this principle:
reduce interference, not increase processing.
Design Philosophy
Telos defines the system through three core variables:
Power
Mechanical Structure
Temperature
These variables determine signal stability. Rather than correcting the signal afterward, the Master Series controls these factors at the source.
Core Technologies
Power Architecture
160V high-capacity capacitors
Custom transformers (flat silicon steel laminations × multi-layer isolation)
Dual-stage regulation × stepped noise filtering
Duelund capacitors × AC noise suppression modules
To ensure the power supply leaves no trace.
Mechanical Structure
Six-sided vibration-damping chassis
Isolation of power / signal / processing sections
CNC-machined high-rigidity aluminum structure
Thermal Management
Large-area aluminum heat conduction
Structural cooling for transformer / power devices / CPU
Fanless design
Digital Architecture
The Master Series is built upon a stable and proven digital computing foundation.
Its digital core is based on a well-established music server architecture, offering reliable system performance and mature software integration capabilities.
For this foundation, Telos adopts the Silent Angel server platform.
