Having lived a Wiim pro plus for 2 weeks now, I’m debating whether to keep it, look at the Cambridge mxn10 or wait for the Wiim Ultra? I have been really impressed by the Pro plus but now that I’ve scratched that itch I’m wondering if spending almost double on the CA will yield a big and noticeable jump in sound? Or maybe the upcoming Ultra will push Wiim into a new territory? (My system consists of Rega Brio-R and Fyne F302i speakers)
