Keces has announced the Ewave Audio Network Switch, a network switch optimized for audio applications. The designers paid close attention to minimizing noise and interference, and incorporating a precise clocking system. Users can toggle ports on and off using switches on the front.
Audio Network Switch
Keces Audio has gained recognition among technically minded hi-fi enthusiasts in recent years, particularly for its power supplies, digital-to-analog converters, and phono amplifiers. With the Ewave, the company is now expanding its portfolio with a new type of device: a network switch specifically designed for use in modern streaming systems where music data is transmitted in real time. Digital music systems require not only data integrity, but timing accuracy and electromagnetic interference can also play a crucial role. According to the manufacturer, the Keces Ewave is specifically designed for digital music systems.
In traditional data networks, the focus is on error-free packet transmission. However, audiophiles argue that this approach is insufficient for audio streaming, as music data must be processed continuously and with precise timing. Timing fluctuations, high-frequency interference, or crosstalk between ports and connected devices can indirectly affect downstream components such as streamers, digital-to-analog converters, or clock systems.
According to the manufacturer, all the electronics in the Keces Ewave were developed entirely in-house. Special attention was paid to the circuit board layout, grounding, and the targeted reduction of electromagnetic and radio-frequency interference.
Accurate clock base via OCXO
The heart of the Keces Ewave is a 25 MHz OCXO, a temperature-stabilized crystal oscillator with exceptionally low phase noise. In practice, this precise clock reference is intended to enable smooth packet transmission and reduce network jitter. For the user, this primarily means more stable operating conditions for streaming clients and servers, especially with high-resolution formats and complex multi-room or Roon installations.
Constant power supply and port isolation
Keces uses an advanced, segmented power supply for the Ewave. The chipset, OCXO, input and output ports, and control unit each have their own multi-stage power path. This is to minimize mutual interference and decouple sensitive circuit components from potential noise sources. Furthermore, individual network ports can be disabled as needed, which helps further reduce unwanted crosstalk in practical setups with a few clearly defined audio devices.
Audio priority QoS and flexible connectivity
Another feature is the QoS configuration tailored to audio applications. This prioritizes audio data streams over other network traffic, preventing interruptions or timing fluctuations when multiple devices are active on the network simultaneously. With eight Gigabit ports supporting 1000, 100, and 10 Mbps, the Ewave can be flexibly integrated into existing home networks with music servers, streamers, NAS devices, and control devices.
The Keces EwaveAudio Network Switch is expected to begin shipping in January 2026.
