“Really hoping WiiM comes out with some deals for the Ultra. Really want to get it but don’t want to pay full price.”

Top Criticism

+21 pts

“I've had the Wiim Pro Plus and the Ultra. I found that the only thing the Ultra added was a screen. The screen has limited functionality. Everything the screen does and more is on their home application. The screen is also too small to be used as an artwork display, it is also slow. It looks cool but not worth the extra money. Also, the Ultra does not work with AirPlay or Siri. I don't use Siri and AirPlay is limited to 48kbs, but at least it's there. I went withe the Ultra Pro Plus, and have not regretted it one bit.”

“Ok. I live in Sweden and had my gear in a room where the radiator failed. It was around 8C / 45F for a few weeks before I fixed it. My Dac/Amp from Fiio (K11 R2R) worked as normal, no issues at all. ”
