I have heard Zu, Wilson, and a bank of speakers from Focal and each of these manufacturers are what I call 0.5 to 0.33 brands. That is, they are mid-level competitive against competitors at 1/2 to 1/3 their cost. So... a 4K Focal speaker tends to compete well against $1500 - $2000 speakers but is way over-priced . These three brands are very overrated.
