Atoll Electronique ST300 Signature – Streamer, UAP and Preamplifier
10.03.2025 05:14 | ~1 minute read
The Atoll Electronique ST300 Signature is presented – a network streamer supporting signals up to PCM up to 24 bit / 192 kHz and DSD up to DSD128. Of course, the device is Roon certified and has built-in Tidal, Qobuz, Spotify and Deezer clients.
The Atoll Electronique ST300 Signature is equipped with full functionality of a digital-to-analog converter – two Burr Brown PCM1792 DAC chips from Texas Instruments and an XLR output cascade with indicators that are calibrated for pairing with proprietary amplifiers. The USB-A port of the Atoll Electronique ST300 Signature can provide power with a current of up to 1 ampere, which allows you to use large-capacity external drives.
In addition, the Atoll Electronique ST300 Signature network player is equipped with a Bluetooth module for wireless streaming. The cherry on the cake is the volume control function using a resistive matrix. If necessary, this regulator can be bypassed, which will be required when connecting the streamer to a preamplifier or integrated amplifier.
The commutation capabilities of the Atoll ST300 Signature streamer include a set of digital S / PDIF inputs, a USB-A port for connecting external drives, an Ethernet RJ45 port and two digital outputs (optical and coaxial). It is worth noting the impressive performance characteristics - a dynamic range and signal-to-noise ratio of 132 dB, an output impedance of 5.6 Ω and a bandwidth of 5 Hz.

Accuphase A-48S – Current Feedback Topology Amplifier
The current feedback amplification topology and powerful power supply of the new Accuphase A-48S amplifier provides a large reserve and stable output in pure Class A. For a load with an impedance of 8 ohms, 50 watts are available, and halving the load impedance doubles the output power. With a short-term drop in load impedance to 1 ohm, the amplifier is capable of delivering a power of 400 watts.
