Why Proton?

Proton Streamers are built using Raspberry Pi 5 as the base, which offers a powerful and efficient platform for high-quality audio streaming. The Raspberry Pi 5's quad-core processor and ample RAM ensure smooth performance and low latency, making it an ideal choice for audiophiles seeking a reliable and versatile streaming solution.

Additionally, the Raspberry Pi is the only board offering I2S DAC support directly via its 40-pin GPIO connector, ensuring the best possible audio fidelity. The cheapest external I2S DACs start around $600 or more, so this is a key differentiator for Proton Streamers in the price-sensitive audiophile market.

By leveraging the Raspberry Pi 5, Proton Streamers provide a cost-effective and customizable solution for music enthusiasts, allowing users to tailor their streaming experience to their specific needs and preferences.

Other brands often skimp on the specs, using older, less powerful hardware that can struggle to keep up with the demands of high-quality audio streaming. Proton offers more for less.

All of our products have 2x USB 2.0 and 2x USB 3.0 ports, dual micro HDMI outputs, and gigabit Ethernet, built-in dual-band 802.11ac Wi-Fi and Bluetooth 5.0/BLE, ensuring compatibility with a wide range of peripherals and network configurations. They will also come installed with an active cooling fan.

The streamers and transports are built using sturdy aluminum enclosures which are easy to open and service in future if needed.
