Possibilty to connect other brands ?

[alandbush]

Hello,
my goal is to make a low cost sound system in the basement, the kitchen and so on in the house where quality is not mandatory.

Could it be possible to connect by wifi low cost speakers visible by the dialog and using spark + My Tidal streaming ?

As has been answered previously, neither Spark nor Dialog can connect outside of the Phantom ecosystem.

However, if you are willing to stop using Spark for your music selection, and replace it with something like, for example, the Mconnect app, then this app can connect to any Phantom, via UPNP, as well as other UPNP enabled speakers.
Mconnect provides access to your music library as well as Tidal, including streaming of MQA titles.
You may find certain Spark type functionality missing but there is a free version available to try called Mconnect lite.
You are then ‘free’ to choose appropriate speakers for each of your rooms from different manufacturers.
