Triangle Competitors?

Zu room. Pillows on the floor spinning some discs, everybody was grooving but I wasn't. 

Me too, at friend's home with their flagship model. I was offering more of a caution than a recommendation. Check out Coincidents if you get a chance to hear them. Cheers,

Same experience here with ZU.  I wanted to like them but nope

ZUs. Look good. Sound non-involving.

fellow French hi-end speakers: JMR ,,,,  high efficiency and dynamic
