Klipsch Cornwall IV

I got my pair of Cornwall IV's last week, and am still breaking them in, but very impressed.  I have been a long time Devore fan, with dabbling with various Harbeths, and others.  I like to swap gear in and out, including speakers.  That cannot be easily done with these, so these require a more serious commitment than usual.  Even my largish o/93's were movable.  So these feel a bit like a marriage, rather than my usual gear swapping.
Out of the box, they sounded a bit stiff, very slightly harsh, and a bit constrained.  Imaging was not the best.  The tonality was not super accurate.  Even with these observations, there was something about them I really liked, and even had they not improved with run-in, I would have felt them worth the price.
I set about running them in, and they improved fairly rapidly, and became dramatically better.  They sound pretty natural now.   Imaging, depth, detail, and transparency, are all excellent.  They are a bit addicting.  I have zero desire to move the Devores or Revels back in.  The bass has thankfully improved immensely.  
I estimate I only have about 100 hrs on them.  Like many, I bought them with a return option.  But there is no way they are going back.  
I have run them with several quality tube amps and a couple solid state amps.  The Cornwalls very clearly identify the characteristics of each amp, yet they sound great on all of them.  There is no sense of the horn origin of the sound.  They just sound like excellent speakers that happen to also have great dynamics and huge scale.
Mine are in the Cherry finish, and look gorgeous.  They are HUGE, so pretty big in my 16 x 14 room, but they work very well nonetheless.
For those considering these, add me to the many who say these are the real deal.  Superb.  

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..

kren0006, I am using 4 combinations of amplification.  Luxman c900u/m900u, arc ref6se/ref160s, Line Magnetic lm210ia, and Line Magnetic lm845 Premium. 

wrm57, lm210ia sounds great on these.  But so do the other combinations above.  I have owned several set 300b amps over the years, and these are the FIRST speakers which are fully fed by 8 wpc, even the woofers.  That said, the other combinations mentioned are all a bit more satisfying in comparison.  But only if compared directly.  The 300b experience is worth trying with a speaker like this.  Your room and power requirements are unique to you.

What I continue to enjoy about these is that they do sound really good (better now than ever) with any and all these very different combinations, even though they clearly illuminate the difference in amplification.  They are the kid on the playground that can play with everyone.

I still have yet to have the desire to move the Devore o/93’s back into place, although I have no desire to sell them either.  They are keepers for me, great also, and for pretty much the same reasons.

wrm57, exactly the differences you might expect. The 845 is fuller sounding, the luxman a bit more transparent. The luxmans are the first solid state combo that is a keeper for me. I have mostly tried passlabs, first watt, ayre, parasound, etc. usually listed them or returned them within a week or so of receiving them. The lux’s have all the transparency and detail of the best solid stated but a bit of the naturalness of tubes.
Yes I have used preamps into the premium. The lower end amps (518) benefit greatly from that, but not this, IMO. It is all transformer coupled and pretty well voiced as it comes. I will also say that upgrading the 845’s to elrogs has a much greater impact on the 518 than on this. As supplied it sounds great!
Also, to elaborate a bit more on the satisfaction level with the lm210ia, it is equally satisfying, but in different ways.  It has different cards to play, mostly in directness and nuance.  It is a keeper also.  In fact I did order a pair of western electrics for it today.

Look at the variety of amps people are using on these!  And everyone is pretty happy.  How unusual is that!
For me I love that you can drive them with virtually any amp, 2-500 Wpc.  I have a decware amp on order, 2.3 wpc.  Last night I was watching the meters on my LM210IA 300b amp, and the most I saw was a bit under 2 watts, so the decware should be ok, even with headroom considerations.
Right now they are driven from 150 wpc Luxman power and they sound fantastic.  
Pinpoint imaging, and as with everything I have tried, the speakers completely disappear.

I’ve always been curious about the Kingko amp!  That could be a great combo!

The bass is not super deep, but I am satisfied and feel no desire to put my svs sb2000 pro into the system.  I would say it is impactful bass, but not super deep.

riaa, are you saying you paid $4k?  You said you “think” you paid that.  That would be a 33% discount...  pretty hard to find that!

Maybe a separate thread for modifying this already great speaker?

Also, for whoever is planning to undertake these “upgrades” perhaps you can make a high quality recording before and after?  There is always an element of a chef liking his own soup.  It is unavoidable.  Also, sometimes a perceived increase in detail can become fatiguing long term...  Not to mention what it does to the resale price.  For myself, I never buy anything that says it has been “modified” or “upgraded”.  
Please no flames, I just don’t want folks tuning in to this thread to feel they should stay away from these because they don’t want to upgrade it.  I have built many amps and am a V-cap fanboy but I am not considering changing one thing about this speaker.  We all have our idea of a perfect tonal balance in a speaker.  For me, this is it, as is.

Well bjesien it sounds like you need both!
For me I always need options.  I don’t always want to hear the same speakers, amps, or sources.  My alternates to the Cornwall 4’s are Dynaudio Heritage Specials, which I also appreciate very much!  They do require different amplification.  While any amps that work on the Heritage Special’s work well with the Cornwalls, not all amps that work well with Cornwall’s, work well with Heritage Specials.
That said, the Cornwall’s are my daily drivers.
Are others also swapping in other speakers occasionally?
