I do have them, set up with the Moon 791/761. I cannot compare them with previous WWPs as I haven’t heard them. But my own experience was simple -- and pretty mind-blowing. I was in the market for a pair of B&W 802D4s to go with the Moons, and auditioned up the B&W food chain starting with the 805s. At the 802s I switched over to the WWPs and (this is admittedly subjective) I was blown away. There was no coming up that rabbit hole without the WWPs so here they are, singing as I write this. They are pretty amazing. I should qualify things by saying that I have a very long run of ethernet cable going to the 791, and plan to either create a short fiber moat or simply add an Etherregen. I can report back if you're interested (though probably it's not too relevant to this discussion).
