IDAGIO is available for BluOS, so you can add IDAGIO as a music service and enjoy your favourite classical music directly in your Bluesound device. Here's how:
Open your BluOS app, on the main menu on the left, select Music Services
Select IDAGIO from the list
Follow the steps in order to log in to your IDAGIO account
Once completed, you can stream IDAGIO directly within the BluOS app
Please note that it is not possible to stream via the Bluesound app unless you are a Premium or Premium+ subscriber.
However, no matter your subscription plan (Free, Premium or Premium+) you can also use AirPlay or Bluetooth to connect your device to your Bluesound speaker and play your music directly from the IDAGIO app. Take a look at the following articles for detailed instructions on how to do that:
