Heresy IV vs Zu DW6/Soul mk2

Zu all the way! Those Heresy's are an outdated long-in-the-tooth design. I was happy to sell mine! Let the stone-throwing by the Klipsch fanatics begin!

Get a good push-pull tube amp like a Dynaco ST70 to use with the Zu’s - I have one. Forget SET tube amps. None of them have enough oomph/watts to work well playing Rock - unlike the ST70’s nearly 40wpc!

I own the Zu DW6s and i've owned Heresy IVs. I prefer the Heresy.

I played a lot of Dead on my Heresy II’s, they present live music very well. Need to Add a sub to get all of Phil. Haven’t heard the Zu speakers, but being high sensitivity I am guessing they play live music well.  

I had the Klipsch Heresy IV, they were dynamic for sure. An SVS sub was needed for my taste. I experienced a good amount of listening fatigue though. I sold them in less than a year. I cant speak on the Zu speakers, they look great and get very positive reviews here at AG. May want to see if you could get a listen to both if possible.

I ended up with Volti Razz and love them. Dynamic and alive like Klipsch with none of the fatigue. They are also sweet, effortless and throw a nice deep and wide soundstage. Right now Greg at Volti is offering an unfinished version of the Razz, great price for what one is getting!
