Anyone listen to Zu Audio's Definition Mk3?

Gsm18439's impression pretty much mirrors my thoughts on them. I have owned the 2's and had the drivers updated to the nano drivers (now speakers are owned by Glory) and that was a significant leap forward in terms of transparency and dynamics while retaining the fundamentals of Zu sound. I spent many hours listening to the 4's after show hours at RMAF and absolutely had to have them after spending enough time dissecting them. For any Definition 2 owner, it is a must have if you can afford them. The bass integration with the downfiring sub vs rear firing will make for much easier integration. More importantly, the bass is so tight, articulate, and palpable compared to the 4 driver array in the 2. It may have been the best bass I heard at all of RMAF. The cabinet is also damped better and has a very solid "thud" when you tap on it with less resonance. The nano drivers are absolutely spectacular and if you can't swing the upgrade to the 4, it's definitely worth the $3500 to upgrade to the 3. The bass amplifier is also much improved both from a modularity standpoint, but also from it's dead silence compared to the hum I heard from the 2's amps. Although it looks like a Definition 2, the only similarities are the spiked feet and the Zu logo. Everything else has been redesigned and this product is a revolutionary, not evolutionary product. When I went to RMAF I had absolutely no intention of upgrading to the 4's but after hearing them, I would have sold a kidney if I had to. I wouldn't have believed the level of performance enhancement of the 4's unless I heard them for myself. I am counting the second until my pair arrives!

As I recall, Zu used split tuning of the four rear firing drivers. While it might have had advantages with that particular configuration, it does not compare to the new single downward firing driver.

The great off-axis imaging (it really does not matter where i sit or stand) as well as the ability to position the 4s within inches of the rear wall were unexpected benefits.

Any more impressions guys? Or comparisons to other Zu speakers?

Hi everyone, as a Def Mk 2 owner I am moving towards upgrading to Mk 4 status. Can those who have heard the Mk 4 comment on the improvements in treble quality with the radian 850 tweeter replacing the previous horn unit, since I feel this was most lacking in my room with the Def 2's. Regards
