Cornwall IV vs. Volti Rival, Razz; Razz v. 1, 2, 3 -- what changed?

A bit late to this thread but timely based on the speakers I picked up on Friday! 

I will post in the next few days a follow up to a thread earlier in the year when I was seeking "coaching" on high efficiency speakers for my system.  After listening to a few different speakers and doing way to much research I went with the Volti Razz.  Since I am in the South, I elected to drive to Volit world headquarters in Baxter, TN and get the full customer "experience".  I will write more in my follow up on all this but after listening to MY speakers in Greg's listening room and having a few days now to listen at home I am confident that I made the right choice.  I will share the whole journey including pre-purchase communication, workshop time with Greg socializing, listening to music and first hand experience with seeing a Razz being built.  Stay tuned..... 

P.S. to my post above - not to sound like a fan boy but I do want to mention for those curious and looking at a Razz that Greg has a beautiful pair in mahogany ready to ship - nicely discounted due to a very slight suppressed "ding" along one front corner of one of the speakers.  Had I seen these in person prior to purchasing mine, I would have definitely pulled the trigger.  Also note that I am not related by business or blood to to Greg but I have shared a few beverages with him :) 

@plinko I think the newest Klipsch speakers (Forte, Cornwall, Klipschorn) are far better than their past versions.

Good to know. If you don’t mind the ask - have you actually compared the different versions first hand? A buddy of mine has owned the 2s, 3s, 4s in the Hersey indicating he likes the more recent 4s are notably better than his prior versions after a more complete redesign. Keeping an eye out for a few friends looking again.

While I’ve read similar posts on the Forte and Cornwalls in the latest versions, I keep an eye out for posts by members who’ve owned and compared version over long periods of time and with different amplifiers types to get a better sense of things.

Also keeping an eye out for posts where lower powered (tube or ss) amplifiers [under 10wpc or in the 10w to 20w range] are used on the later 4 version speakers with notable success. Apparently sound great when matched up with good amps.
