Anyone listen to Zu Audio's Definition Mk3?

Perfect. Def 4 is the single most convincing speaker of practical economics, amp requirements, size, and universality of room application I've encountered in 40 years of looking for gear in this realm.

It also fits perfectly with amplification decisions that have proven stable for seven years. I changed one preamp out of two systems to more closely complement the change from Def2 to Def4. And Def4's superior conveyance of digital listening sparked a new investigation of DACs and an imminent server configuration. Nothing but positives.

Like Phil (and unlike Glory's comment), I have nothing but positives to say about my Def 4s. . . now in their 8th month. The only downside is that I am now buying way too much music.

Boys and girls it was to be a Ha Ha momentt.

Zu Def speakers should retail at 20K as I have heard 20K speakers that sound broken compared to the Def.

So glad the buzz on the Def 4s is uniformly positive. As I've said on this thread before, I've purchased sound unheard based purely on my experience of the 2s over the last few years.
A recent tt purchase has been really positive but aspects of it's spound have challenged poss lack of transparency in the 2s. I'm hoping the improved nano FRDs in the 4s are going to improve this side of audio reproduction.

Glory, i WAS in on the joke. However since so many in the audiophile community change their equipment as fast as they change their underwear, there may have been some truth in your statement.
Great to hear that you (and 213cobra/Gsm18439) believe these speakers are up there with those in the upper level of performers. Although, with the frankly ludicrous prices being charged for the state of the art in loudspeakers, thank God for Zu Audio and their real world approach to performance/price ratio.
