Heresy IV vs Zu DW6/Soul mk2

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!

Lack of deep bass is actually a plus, I’m in a townhouse and those lower notes seem to slip past walls more easily. I have a 45watt push pull tube integrated so all set there as well.  I’ll check out the Volti’s never heard of them, they seem to resemble the Forte.  I definitely don’t want listener fatigue though. I’ve heard conflicting reports on Klipsch.  I have hard wood floors with a large area rug, coffee table and sectional leather couch to soak up extra treble, but my current speakers are soft domes so fatigue was never an issue, I’m not sure how other speakers will respond
