Op, this is a used item (new for $219), and I’ve had no issues using it. It comes with a remote, and I tested it once and made sure it works. I’ve been using it in my second and third systems for streaming Qobuz on my iphone. In addition to the WiiM app, you can also stream via Qobuz Connect, which, in my opinion, sounds slightly better than the native app. I’m not sure if Tidal Connect behaves the same way. I haven’t experienced any issues with it. I’ll put together a YT demo and send it to you.
When you use things like Qobuz Connect, TIDAL Connect, or native apps, the phone is just sending commands (play, pause, select track). The actual audio stream goes directly from the internet to the streamer thru ethernet or wi-fi, not through your phone.
Once again, as an owner of the WiiM Pro+, Ultra, and the newcomer Node Nano, I can say the Nano sounds noticeably better. There are used Nanos selling for less than twice the price I’m offering for the Pro+, but I can tell you it’s worth the “upgrade. I don’t need to sell you my WiiM unit—I just want to be honest with you.
