Klipsch Cornwall IV

If the new ones are anything like the older ones Id say pull the trigger but if not do what I did and get a vintage pair.

As far as soundstage size and dynamics, they are the same. Anything else, they are a whole new ball game.

While I can't add anything to Cornwall discussion, I find it interesting there seem to be little or no complaints about timbre issues. It appears Klipsch has done some work here?
I purchased used late 80's era Klipschorns about five years ago, my initial impression was really amazing dynamics, particularly micro, and same with resolving powers. Tonal balance just a bit off, mids too dominant. Much less impressed with timbre, naturalness not this speakers calling card. In a relatively short period of time I became convinced I couldn't live with these speakers, timbre so far from natural. This coming from Merlin VSM-MM, much modified with Duelund VSF copper foil caps in every possible position and so much more. Anyway, timbre was probably the greatest asset of the Merlins, so lack of this in Klipschorns was brought out in great relief.

So, to cut to the chase, five years later, Klipschorns modified to the point where only bass cabinet stock. These are the last speakers I will ever own. No other speakers I've experienced replicates the sense of live performers in room like Klipschorns, and I presume others in the Heritage line. Based on the above comments sounds like Klipsch has certainly improved upon timbre issues in earlier iterations of Heritage series.

Enjoying these more every day!  They continue to surprise me with their revealing nature.  They sound great with high power amps, and low power amps.  
I did add Herbie's Huge Sliders, and I think they tightened up the bass a bit and increased focus.  I did not know what to expect since I have seen a post saying they reduced the bass, but not for me.  No downside, all upside.
I do have some nice amps, but since these are so easy to drive, I ordered nice Line Magnetic LM 210IA 300B amp, and a Decware SE84UFO amp.  Kind of looking forward to seeing what a 2 watt amp does on these..

I'm looking forward to hearing your feedback on the new amps. I just picked up a Triode Lab 2a3 amp, just waiting for it to arrive.

Having a lot of flexibility with amps was one of the things that led me to the Klipsch heritage speakers, ultimately the Cornwall IV. 

For sure dbarger tell us about the amps that you’ve tried the CW4 with and about the differences you heard. It sounds like you’ve already tried several with more to come. TIA
