Zu introduces Soul 6

Wow what a great write up - thanks Phil! This is the clearest Zu review I have seen yet, and helps me so much as I contemplate my next speaker move. 
 

I currently run two systems - the “big” system consists of restored stacked Quad 57’s fed by Atmasphere M60’s. My “casual vintage” living room system consists of a restored Marantz 8b amp + McIntosh MX110z into a trusty but tired pair of 1964 Wharfedale W90’s. Needless to say the Quads have ruined me for pretty much all other speakers. I tried replacing the W90’s with a pair of Devore O93’s to try a vintage + modern approach, but felt the O93s sounded slow and sluggish, and overly rich - esp when compared to the Quads. So, I sold them and am wanting to try the vintage + modern approach again, but this time maybe with a pair of Zu Soul 6’s. Based on everything I’ve read, they sound like a good match for the 8b, and have lots of speed and snap - closer to the Quad sound. They also have high WAF, and would fit in nicely with the rest of my mid century decor and gear, a big plus. 

I was also considering the Soul Supremes, but it seems like they would need a sub based on what I’ve read, and what i am trying to achieve. Plus, Soul Supremes are now up to $5k in the finish I want (American walnut), so it seems like a better idea to just cough up an extra 1k for the 6’s? The most important thing to me is how the 6’s sound on electric guitars (Zappa, ZZ Top, Paige, Clapton etc). I am a guitar player and collector, so the tone being “just right” is always my main goal.

Also wanted to ask Phil - Do you have any additional observations or comments after living with the 6’s for a few more months? Any other new Soul 6 owners want to chime in? Thanks!

@213cobra thanks for all of this great info! Quite an endorsement to hear how favorably they compare (and in some ways surpass) the mighty Quads. Sounds like you and I are on the same page ear-wise, so I really value your write-ups. 
 

Another thing I wanted to ask is if you detected any horn like colorations or shout from the tweeter on the Soul 6? I am a bit sensitive to this, and any actual horn loaded speaker usually gives me a headache (any Klipsch and some Altec I have heard). It doesn’t appear that way but just wanted to see what your thoughts were on that. 
 

Sounds like there’s a pair of S6’s in my future and I’m very excited about it!

Thanks Phil, and thank you for the Mesa el34 tip - I have been using NOS Mullard XF2’s and they are hard to find and not cheap!
