    Thrift store DVD player with a good DAC like SMSL SU-1 will sound like a £1000 CD player. For £100.

    With a good $1000 DAC, sure, there will be imorovements. With SMSL SU-1, no I don't think so.

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

    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.
