I have a pair of Cornwalls and I love them. Any time I listen to other people's setups, or at a hifi shop, the sound is really dull and lifeless to me. I think what turns people off at the start is that they are really in your face and to a point, that might sound shrill to some.

I began with Heresy I's twenry years ago, sold them to my brother who still has them. Upgraded to Cornwall I's, sold them to a friend who still has them. Dabbled in Magnapans and was disappointed. Now I own a pair of MINT 1986 Klipsch Belle's with upgraded Crites tweeters and crossovers. They are not for sale.
I love my Heritage Klipsch!

The old Reference Series are nice speakers. I used the original RF-7's for over 10 years in my main system with Zen, Super Zen and UFO. These were plenty loud but with only two watts still required a sub for real Rock & Roll.

Should note the RF-7's can sound a bit shrill with a number of solid state amps I tried. As far as solid state the best combo I found was my Peachtree 220SE (220 watts / channel) with the RF-7's. With this kind of power they will go very loud and pound out the bass but you probably won't want to listen at these levels regularly. The Peachtree sound is very smooth on the ears with Klipsch.

The UFO has much more detail & space at moderate listening levels compared to solid state amps I have used (this includes the Peachtree). My RF-7's now reside in my second system with a Super Zen and sometimes the Peachtree.

My main system now has Single Driver Omega Monitors (no crossover) and custom dual Subs. IMO eliminating the passive crossover makes a big difference. Since for my taste I require a sub, I prefer Monitor speakers to towers. Monitors are easier to place and generally sound tighter to me. Like everything else audio, there are exceptions.

My Belle's are simply delightful with the 2.3 watt Zen. No "glare" or "harshness", at least to my ears. Please note, I'm no audiophile. The heritage series seem to hold their value well enough in the used market and they also seem to sell quickly. I think used Hereseys are a good start and as they are "small" Klipsch and relatively inexpensive and easy to sell. They will lack some low end bass and may require supplementing with a subwoofer. I've seen them used for 300-1000 depending on finish, condition, and series (I, II, III). Had my first pair for 18 years, my brother now owns them and uses them daily.
Klipsch has a forum with a ton of info and some really nice folks. It might be with a look.  

Cornwalls, La Scalas, Klipschorns, and Belles are LARGE speakers and may not sell as quickly as the Hereseys if you don't like the sound.

I have owned Belle',s Klipschorns, Cornwalls, Chorus II's, Heresy III's, RF-7II's. I regret not hearing any of them on a Decware amp. I wish I could here them on my JR.. I would recommend to anyone to try them, they are fun dynamic speakers.

Blue, I'd gladly jump on a good offer for a set of Cornwalls but truth is, I don't have space for them.  Them things are wide and I don't have that kind of space.  I have a pair of MG944s that barely fit.  I mean, I don't have anything close to a descent place to setup my gear.

I'm in the middle of searching for new digs.   But, I will have to wait until then.

Anybody ever compare Bob Crites' stuff (specifically the Cornscala) to vintage Klipsch?
