Klipschorn: Still relevant??

Klipsch do some things very well, but they are not modern speakers. If you want to get serious about horns you might want to consider something like the Classic Audio Reproduction line. They use much better drivers and parts than Klipsch and it's reflected in the sound quality.

If you're stuck on Klipsch, search the archives, there were several threads on how to upgrade their performance through relatively simple parts swaps.

In direct answer to your original question, no - the Klipsch will not be better than what you have if by better you mean higher levels of fidelity.

Pawlowski, it might be helpful if you stated what is so wrong with your system that you want to make such a major change. Your original post makes it sound like you're just bored and want to change just to change.

In broad generalizations, SETs can be very seductive, but it's critical that you match them to a sympathetic speaker and to appropriate music. Small scale jazz, female vocal oriented stuff, chamber music, etc. is better suited for most SETs than full scale orchestra, dance, metal, rap, etc. Of course there are people out there who listen to Metallica thru a single driver horn powered by 1.5 watts and think it sounds great, and you could be one of them, but most likely you're not. I've never heard the combination of equipment you have, but on paper it seems first rate. I suspect you will have a difficult time truly improving upon the overall sound quality. Exactly what are you trying to accomplish?

Larry510, you're the one who claims the CARs may be a little better than your Cornwalls. Others might not be so kind.

Pawlowski, do yourself a favor. Don't change anything. There are better systems than yours, some might even be less expensive than what you spent, but ultimately what difference does any of that make as long as you like the way your system performs. If you need a point of reference, then start a post about starting an audiophile club. There could be dozens of people who live near you in the same situation you are. If that doesn't work, take a vacation and visit some manufacturers factories. Most factories have really good reference systems that they might let you listen to. Call ahead of time and make arrangements. The cost of the travel is way less than the time, effort and money spent swapping out equipment that makes other people happy.

Larry510, why should he spend up to $2,500 to get inferior overall sound than what he already has?

Larry510, is it possible for you to imagine that some people have listened to Klipsch (Heresy, LaScala, KHorn) speakers and didn't fall in love with them. Maybe they wanted a speaker that went deeper in the bass, or one that soundstaged with more front to back depth, or possibly a more refined treble range, or even a less forward midrange. Just try to imagine.

One size doesn't fit all.
