Network Player Ypsilon Electronics S 100 Silver

Network streamer with direct memory architecture and FEMTO clocking for time-accurate reproduction

The S100 streamer is a digital source designed to remain as transparent as possible to the music being played. Instead of relying on off-the-shelf modules, a completely in-house solution was created, built around a direct memory architecture. Audio data is first loaded into memory and only then clocked by highly precise FEMTO clocks for all sample rate families, with the output connected directly to the audio connectors.

This arrangement separates the computing section from playback itself — the generation of the digital audio signal is governed directly by the clocks, not by software timing. The result is significantly lower jitter and noise than mass-produced streaming platforms typically achieve. The entire hardware is custom developed and powered by discrete linear regulators, which draw from a bespoke, hand-wound transformer and choke filter intended exclusively for the S100.

The hardware is brought to life by an operating system and drivers developed exclusively for this unit, ensuring stable and predictable operation throughout the whole chain. Precise clocking and a low noise floor translate into legible microdynamics, rock-solid instrument localisation within the stereo image and a calm background from which reverb tails emerge without digital hardness.

Connectivity covers I2S over HDMI and USB with support for PCM up to 768 kHz/32 bit and native DSD512, coaxial and AES outputs up to 192 kHz/32 bit, and gigabit Ethernet. Control is handled through the companion mobile app for iOS and Android, which allows you to choose your preferred playback software and manage the device's functions. Power consumption reaches a maximum of 40 W, dimensions are 400 × 135 × 330 mm and the weight is 15 kg.
