Attention Horn Owners

Larry. My first tube amp from Vu was a Synthesis push pull el84 amp. It had that punch for sure. I matched it with Zu Soul Supreme speakers and had extreme ear fatigue really quickly. Headache would last hours. I tried all sorts of treatments around the room. In my rush to find a fix, I sold the Zu’s and decided to sell the amp as well. The amp had to be biased by hand, by going in with a screw driver next to that power storing transformer! It also had a built in dac. At the time, I wanted to play around with various sounding dacs and find one that really was my sound. So off it went. That Synthesis a-40 gets great reviews but same situation. 
So, depending on trade in or personal sale, I may try the Soro se signature or scrap tubes and try a Pass Labs int-60. Both are 1 box solutions. 

Btw sns, I might be leaning towards the Kef kc-92. I’d like to start with one sub and the dual opposed provides a bit more. More research before I pull the trigger though. I’m an impulsive person when it comes to these things but amp sale or trade in forces me to slow down. That process will dictate the direction I head I suppose. 

I have never heard a Zu speaker that I could stand--very bright, lean and harsh sounding.  I think it gets attention because it is extremely lively sounding, and that is a BIG contrast with most modern speakers which tend to sound lifeless.  

Yep. They are good party speakers for big rooms and young ears. I enjoy my buddies when I’m in the next room but not in front of. 

What’s weird is checking the frequency response of the all Zu’s, they have a spike at both the 2 and 5khz. This is total ear fatigue area. Not sure why any speaker designs it this way. From my very limited understanding, it’s not necessarily the curve but spikes in that region that humans are susceptible to ear fatigue. Please don’t quote me though. I did read up on it when I was suffering but that was awhile back.
