Tube amp Friendly Speaker That Sounds like Klipsch Cornwall

There are so many excellent speakers it's hard to say what's best. Then you have rooms, amplifiers, dacs, sources... It's tough to be an audiophile, lol. Everything will be a different flavor, with some areas excelling over others and some not as much.

If I had unlimited funds, I'd probably try them all to find the "perfect" sound. As it is, I have very happily "settled" for Cornwall IV's and a Luxman L509X and enjoy wonderful music with a three mile smile. I love horns so some bias there, but I feel the Cornwalls are the best there is in their price range.

If you want something that sounds like Cornwalls then get them! If you want less 'in you face ' try Heresy IVs with a pair of quality subs. They are also beautiful sounding but more subtle.

I was intrigued by the Cornwall IV and went to my local dealer that had the Forte 3 and the  la-scala on the floor (no cornwalls). I am also a long time Thiel owner (2.4). 
 The fortes were just hooked up to an integra reciver and sounded pretty bad to me. No life and lacked impact in the bass. Mids were nice enough, wide, and nothing stood out as terrible. Highs were clean enough but nothing but the facts kind of sound. As a whole the speaker did not impressive me in anyway at all.
I brought a small headphone setup as a reference (helps me demo, but I look like a total weirdo...) and switched back and forth as I often do at home (late night, kids and family life calls for headphones sometimes). Anyway the setup sounded bad enough my headphones sounded amazing in comparison (the headphones normally sound bad right after my home speaker rig). 
It turned me off enough I did not demo the   la-scalas. 
I am 99% sure the integra was most of the problem and could ask to have them hooked up to proper gear but I am not sure I will bother. I am still interested in the Cornwall iv. The build leaves a lot to be desired based on YouTube videos but could be something fun to play with regardless of the poor build.   
Not sure what to think as the Cornwall IV and to a much lesser degree the fortes have been getting universal praise more or less. 
The question I ask myself is, Are the Cornwall IV really a good speaker or does the build hold them back? 
I would be running them with duel subs using an active crossover but I think all systems need subs....

The additional bracing and horn ports of the  CW IV have erased the boxiness of Cornwalls of yore. I'm not sure exactly what you mean by poor build quality of this speaker. Sure the xover could have better quality parts, but that's all I can think of that I would change. And the sound is so good that I don't even give that much thought either.

The exterior fit and finish seems very appropriate for a 6K dollar speaker.

The key is the match.  I used to have a pair of Maggie 3.5R's.  I found them as responsive as a giant hunk of granite.  They loved the power and took a high current to drive.  When you hit the sweet spot though, wow.  It was such an exact speaker that you could hear people talking in the background of lots of the Beatles recordings.  After several other trades and evolutions, I moved to the Altec Lansing A7-500's (16 ohm).  Tried these using the same amp as the Maggie's and felt the sound quality went down.  The horn could be piercing and the woofer wompy.  When hooked up to a 6 watt SET however, its the sweetest, most wonderful sounding system I have ever heard, a true toe curler.  The horn sound that was there using the higher power amp went away and the bass is a sweet reach around hug.  This combination actually sounds good at lower volumes and gets adequately loud enough that my wife can hear me, from our second floor, very well, from a sound dampened basement (I blame the hvac).  If you are buying new, you need to ask to audition.  If its a really good place that you have done business with, this shouldn't be an issue.  Otherwise, load up your amp and other accoutrements and head to the store.  If still denied, buy somewhere else.  I view this as going to buy a car without a test drive.  What some places want you to do is sit in their car and just say vroom, vroom and imagine.  Get as close as you to what your system will be prior to buying and believe your ears and not someone else's.  The Cornwall's as sensitive as they are, they just need the proper amp.  Using pipes as a metaphor, your Maggie's are like the drain pipes coming off of Hoover dam and the Cornwall's are like the pipes in a cathedral organ.  Each beautiful but totally different. 

Oz,

Just lack of bracing is what I was thinking about. It does not seem like there is any side bracing that is typical for higher end speakers. Think B&W “matrix” bracing.

I have always rationalized bracing to be important in my head but have never tried bracing in isolation so hard to say how much it matters at normal listening volumes (I am not a loud listener. 85db Max)
Good point about the ports. I overlooked the value of that. 
Anyway I value dynamic (transients and impact) above all things and still want to hear these and possible buy them as a total step change to what I am used too. At $6k these are a cheap option is our crazy world lol. 
I follow your posts and many others that say they are good so I assume they are.
