Fantastic product and works well

Both the up2stream amp and up2stream pro work great and I am very pleased on what I payed for.

Just some comments on ways to maybe improve or products that I would find super helpful.
In the app I found it difficult to find the place where you switch from Bluetooth mode, to WiFi, ect.
I also didn’t see in the instructions where it said there was a button to do that which would have been nice.

For other products that I think would be awesome for full house audio.
A device that takes in arc hdmi that will convert to surround sound and either send it to an up2stream device or at least I could hook up and external amp to it and wire in my speakers.
Basically It’d be nice to have a solution that allows for surround sound with my ceiling speakers and also be able to use them for music/broadcasts for the whole house

Decent product for a reasonable price

The amp is working quite fine despite some issues. For me, the 4stream app works not so good and basically can connect to the amp only after plugging it to power supply. After turning off and on by remote, app did not find the amp. Steering via web page does not work at all, shows some controls with loading bar and does nothing. Also playing internet radio is quite poor, stream stops and jams no matter what station I am trying to listen - it is not related to network connection because the same stream opened in mobile phone and streamed via Bluetooth plays well. Hopefully these are some software issues and maybe firmware upgrade will help when new will be released.
