Atoll ST200 Signature Network Streamer, Black

The Atoll ST200 Signature is a network streamer with D/A converter and its own volume control, playing music from the network, from USB and from digital sources.

It's the entry point into Atoll's full-format streaming – and one where the manufacturer didn't cut corners: separate transformers for the analogue and digital sections, 27,000 µF of filter capacitance and a large display you can actually read from the sofa.

Why the ST200 Signature?

Because it shortens the chain. A Burr-Brown PCM1792 converts up to 24-bit / 192 kHz including DSD, then the signal goes via a regulated output stage straight to a power amp – or at fixed level to an integrated amplifier, whichever you prefer. Two line inputs, four S/PDIF inputs and two USB-A sockets also make it a collection point for anything digital.

What you get

Access to pretty much everything: Qobuz, Tidal with Tidal Connect, Spotify Connect, Deezer, Amazon Music, HighResAudio, internet radio, plus Roon Ready, AirPlay 2 and UPnP/DLNA for your own collection on the home network. You control it via the Atoll app, the 13-centimetre colour display or the remote control – and if a feature was missing, Atoll has so far usually added it later via a firmware update.

Who is the ST200 Signature for?

For anyone who wants to add a serious network source to their CD and vinyl setup – and for anyone happy to get by with a streamer plus power amp. Plain talk: it has no XLR output, that only comes with the ST300 Signature. It can't do phono, and it doesn't take option cards. And if you only ever listen to Bluetooth from your phone, you don't need this device – a fraction of it will do.

Our verdict

The ST200 Signature is the sensible point in Atoll's streaming line-up: everything you need day to day, without paying extra for the last percent. Neven Kos wrote in July 2023 on enjoythemusic.com: «The ATOLL ST200 Signature Streamer / DAC / Preamplifier is a pleasure to use for its excellent application, screen, remote control and designed functionality.» Not sure whether a streamer plus power amp is enough for you, or whether you need an integrated amp after all?

Frequently asked questions

Can the Atoll ST200 Signature drive a power amp directly?
Yes. The ST200 Signature has its own volume control and outputs up to 2.6 volts. That means it replaces the preamp in a lean chain. You can run it into an integrated amplifier just the same – the amplifier then takes over the level control.

What's the difference between the ST200 Signature and the ST300 Signature?
The ST300 Signature has two converter chips instead of one, a considerably larger power supply (69,000 instead of 27,000 µF) and an additional balanced XLR output. The ST200 Signature offers the same streaming feature set, just one notch down in build.

Is the Atoll ST200 Signature Roon Ready?
Yes, officially certified. On top of that come AirPlay 2, Tidal Connect, Spotify Connect, Qobuz, Deezer, Amazon Music, HighResAudio, internet radio and UPnP/DLNA. It's controlled via the Atoll app, the colour display or the remote control.

Can I connect headphones to the ST200 Signature?
Yes, there's a 3.5 mm jack on the front. That's plenty for the occasional headphone evening. If you listen daily and with demanding headphones, you're much better off with a dedicated headphone amplifier.

Why buy the Atoll ST200 Signature from HD Zürisee?
Because half the work with a streamer happens in the network. We set it up, connect it reliably to your Wi-Fi or LAN, sort out your library and show you the app. Installation and service are handled by our own technician.
