    Build quality


    Atoll Electronique hasn't rested on its laurels. They have improved everything that was good about the Atoll ST200 Signature and put it in the St300. Dual mono construction, dual mono dac chips, dual analogue volume control and so on. Actually, the ST300 Signature (€3000) goes further in every way.  The build quality, the components used and the thoughtful design make it a top performer. We never felt inclined to take the ST300 Signature out of the system and that is the biggest compliment we can give this device. Fewer components, fewer cables, fewer powercords and less clutter. Less is indeed more. Alpha Approved.

    For whom


    We’ve been testing a lot of all-in-one devices lately. The Cambridge Evo 150, Lyndorf 2170 or Marantz 40N to name but a few. The Atoll ST300 can stand proudly amongst them. Even more so we find it to be one of the best in class and could easily live with it. Both in terms of playback, usability and versatility. The dac is excellent and now that Roon is on board, there is nothing stopping Atoll Electronique from becoming a serious player on the streaming market. If you’re currently unsatisfied with your individual components, ask for a demo of the ST300 Signature. You will be surprised how far you can get with these devices nowadays. You’re also going to suffer far less “audiophillia nervosa” and spend more time with your favorite music. If the ST300 is just out of reach for you,  the ST200 Signature will be an excellent “second” choice. We think the difference in playback between the two won’t be that big. But that’s just the nature of this hobby. You can always do a little bit better.

    1. Can someone please clarify Geoffrey’s comment “ You can dim the screen or even turn it off but we think that’s only necessary if you’re streaming via Nas and don’t get cover art”

      What exactly does he mean?

      With my ST200 you get full cover art support but the cover art must be present on the attached NAS drive.


        1. Thank you Geoffrey, please report back or maybe update your review if possible. I have zero issues with my ST200 Signature with our attached Buffalo NAS drive and cover art.

          The only issue or complaint I would have with Atoll streamers and I reported this to Atoll already is the limited support for attached USB or NAS drives when it comes to searching for artist (extremely slow).

          It is highly recommend to use some type of server software like: MinimServer or Jriver to help speed things up.

          Thanks again,

      1. I think it is a best practice to use UPnPServer software like JRiver, AssetUPnP, Audirvana or MinimServer if you like to stream local content to a streamer or streamer/DAC combination. Or choose Roon if that is supported and you like its functionality.
