Great product.

Chris Aitken
Great Airplay receiver

Great Apple Airplay wifi receiver to power my bookshelf speakers.

Ben Lambe
Not perfect but better than most, at least from what I can find.

Has issues when switching inputs. Would be nice if it switched based off of signal received from the inputs so as to be automatic. Also a decent cast function or even playing anything over the network direct LAN method instead of Bluetooth would be nice, I understand this is somewhat the software that the user is using and not your device from just this issue. However still testing the invention I made with them and for the most part since I mostly use the connection method AUX in. Which I did only because the above methods are not fast enough for MUSIC MAKING as there is a delay BIG TIME delay when using any other method of connection. If you have a suggestion for what I should do here which may solve these issues. I would be making your company a lot of money.

DIY amp

Looks good, will buy more soon

K. M.

Great DIY device, and easy to install.

Fantastic little board

Feature rich and highly appropriate for DIY builds, I've integrated this with my stereo transmission line build. Upstream v4 was my first DIY board and since have decided to order a bunch more within a month.
The iOS app can benefit from a more elegant redesign and a greater degree of equalisation within the app. although once DSP has been tuned for the dedicated application not much if any eq is really required.

The support and fulfilment team are excellent!
Good job Arylic!
