Overall functionality, sound, and quality of the unit is excellent. My complaints are very far down on my list of concerns. I do wish it had a line-level analogue output, and more analogue inputs.
Really impressed with this speaker. Sounds amazing and works flawlessly. I use it with an Amp Pro to sync with my turntable and play records in multiple rooms. Already planning to get a couple more.
I've installed several of these for customers and wanted to try one for myself. Great amp, lots of features, reasonable price.
The WIIM Ultra surpassed all of my expectations. I love it! It does so much more than what was advertised. WIFI, and Bluetooth capability is great. I use Tidal over wifi and simple radio from my phone using Bluetooth. Granted Bluetooth doesn't have the capability that wifi has, but that's what Tidal is for over wifi. I was impressed with all the sound adjustments that can be made from the app, and that it will adjust balance between speakers with "roomfit". I was originally looking at Sonos, but this device has a much better dac and frequency range plus it is less expensive.
The Ultra sounds amazing! Best upgrade for my speakers I’ve ever heard (used to just stream from my phone). The app is easy to use, too, including room sound correction. The on-screen controls are great for when you don’t want to use a phone. Love this product!
