There’s a difference between what I might want from a new/existing product and what I think might make WiiM products more successful. I use an external DAC to excellent effect but reading most reviews of the products the only aspect where the WiiM family seems to fall short of, say, Bluesound is the analogue output quality. I suspect most contributors to this forum are also using external DACs, but it is easy to forget that the vast majority of people want to just plug the device straight into a speaker or non-DAC-containing amp.
My vote would be to include a higher quality DAC in a Pro2/Ultra (+/- USB out) and then completely own the sub-$1000 streaming category. By doing so, even the likes of Apple Music might then wish to talk with you.
