Anyone listen to Zu Audio's Definition Mk3?

Well from your description Phil, one to look fwd to. Despite it's hefty price tag, a relative bargain in the high end wrt models like Magico, Wilson, Rockport, YG. It's in that big bucks league at a third of the entry ticket.
You feel that the Def4s, despite not scaling the absolute lofty heights of the Dominance, doesn't give too much away in performance terms comparison I hope?

Definition 4 overperforms at its price, relative to the market. It can be a "last speaker" for many people and is far better than most audiophiles or musicophiles will own.

If you hear Dominance, you leave mentally rummaging through your house looking for all the things you can sell to pay for them but when you return home listening to Definition 4s, you aren't left feeling deprived and wearing a permanent frown.

I already prefer Definition 4 to any Magico I've heard, though the Magico Q5 is certainly quite good.

Phil, thanks for your thoughts on that. I have enough justification to make spending the cash on the Def4s without running to a bill 3x + their cost to consider the Dominances!
My guess with Sean, is that they might be the ultimate testing board to refine ideas for spkrs like the Def4s they're likely to sell many more of.
Anyhow, within 4-6 weeks I'll be providing a home for a new pair of Def4s, can I just take this moment to thank you for your really informed, enthusiastic comments on the 4s. It is primarily these positive descriptions (and those of others eg GSM) of the quality differences between the 4s and 2s which gave me so much confidence to make the upgrade without prior audition. In effect Sean should be thanking you too, lol!

Although I have neither seen nor heard the Dominance, it is twice the footprint, 25% taller, and 250% the volume of the Def 4s. Not insignificant for real-world applications.

When Zu says Definition offers the maximum loudspeaker performance available in about 1 square-foot of floor space regardless of price, I think they are right and that footprint happens to be practical even for many customers at least in the US who don't have extravagent digs. You really must have an extraordinary commitment to domestic high-fidelity music reproduction to go further in a loudspeaker. But of course in a pursuit like this, there's a lot of elasticity to where any two individuals would place the boundary demarcating the threshold of "extraordinary commitment." In a market sense, is Dominance worth its size and price? Yes, but only a relative handful of people will think so.
