Heresy IV vs Zu DW6/Soul mk2

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 

@perkadin The Razz and the Forte do look a lot alike. Not to knock the Forte in any way, in my opinion the Razz sounds much better, the cabinet is made of higher grade material, and the drivers too are higher quality. It's tough to compare a somewhat smaller builder/artisan like Greg, to a big player in the market like Klipsch (or JBL for that matter.) They are loved the world over for good reason. Just for my tastes and the joy of the chase, the Volti just hit all my happy buttons. 

You may consider stand mounts. I've heard the Golden ear BRX monitors several times and they are liquid gold. Surprise me every time that such  full and musical sounds could come out of a monitor. Plus they much cheaper than those we've been discussing. I also have at home a pair of Tyler T1 Time Keepers. They sound amazing too. They are a bit power hungry tho... Very pretty speaker, I got the stands too from Ty. Pretty great guy to deal with, Like Greg from Volti.  Tannoy and Fyne in the dual concentric camp are pretty great. I sold Tannoy at a local shop back when, I was completely smitten with them. The Tannoy Eaton or Cheviot.. one day I will own a pair. 

Some dealers and manufactures will allow in home trial periods. That way you can bring them home, real world listening in home turf.  

I have listened to ZU speakers at audio shows and always felt they were a bit bright and in your face.  The Klipsch series IV speakers are their newest and really sound wonderful.   I’m still looking for a used pair of Cornwalls series IV for a decent price. 

I’ll toss my vote in for the Zu’s too.  I have a SET 300B that I use with my Zu Soul Supremes.   I listen to a ton of live Dead (Dave’s & Dick’s Picks and all the box sets).  The Zu’s throw a great soundstage (and aren’t bright).  I couldn’t be happier but I would love to try the Volti Razz in my room, but I really don’t see it happening. 

I’ve been living happily with the Zu SS’s for about 6-7 years.  I’ve used different amps, First Watt F8 and SIT3.  Depending on your amp you might want to get the impedance wrangling resistors to make them look like 8 ohms to your amp. 
 

Enjoy!

I can't speak for the Zu, but I have the Heresy IV and have not found them to be fatiguing at all.  It's hard for me to think how another speaker, other than another Klipsch Heritage like the Forte IV, could sound better for live presentation.  

Also consider the following: the Heresy maintain a dynamism and "live feel" even at LOW listening levels, and moderate levels...  That's one thing that really impresses me about them; I usually listen at low-ish levels and I'm continually taken aback by how fresh and impactful they sound.

That said, are they my "lifetime" speakers after a lifetime of listening through the "linear sound" of Epi 100s...?  Maybe not, and I'm going to give the Q Acoustics Concept 50 a try, see what I like better as my "forever" speaker... but I do not regret my Heresy purchase and they have really brought a lot of engagement and they are addictive such that I might not be able to let them go and could see "rotating" them in from for part of each year just to freshen things up a bit, even if I do ultimately settle on the Concept 50 as my primary.
