Topping DX3 Pro+ vs WiiM Ultra

“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.”

“I bought the Topping DX3 Pro+ last week and within 24hours is just died, stopped detecting any input source so I returned it to Amazon disheartened. I really loved the sound but immediately noticed some quirks which should not have been quirks like not being able to change volume display between % and dB, or the fact that the lowest display brightness differs between both MX and DX which bothered me. The Custom menu on the DX also has limited options compared to the MX3s, why? No reason for it! So someone recommended the Fiio K7, more powerful, balanced output, no display or faff, no remote, just a big dial and loads of power. I love the headphones out of the MX3s, but it's obvious the HD650s want more power than what the 100mW x2 @ 300 ohm MX puts out, I have to put the MX at -2dB to match the loudness of the K7's dial at 3 o'clock and that's just with the 6.35mm output which is 140mW @ 300 ohms. Had the 650s since 2014 and finally now getting the most out of them, balanced and 540mW 😎”
