Cornwall IV – new amp vs crossover upgrade

I recently bought Cornwall IVs and basically I´m very happy with them – they just sound very pleasant. And I haven´t even upgraded to another amp yet which seems to be the next logical step. When I was in the store I tested them with a class AB and a hybrid amp and I could already tell that the hybrid made them sing. Currently I´m using an old, small Rotel amp and they do sound great with it but I know there´s plenty of room for improvement.

Having read a few things here and there, I´m wondering which has the bigger impact: a new amp or a new set of crossovers. Sure, it´s all individual but with people raving about non-Klipsch-crossovers and other improvement (for example damping the horns as suggested by the Boston Audiophile), I´m not exactly sure what should be next. Would a nice tube amp make a crossover upgrade unneccessary? It´s hard to tell from what I´ve read.

As much as I like them, I feel right now they are lacking a bit of overall warmth. On the other hand the highs are a bit too pronounced and detailed for me which led me to turn down the highs on the amp a bit. There are some recordings that just match the current setup and listening to them puts a big smile on my face. And I just feel that this can be extended to more albums.

Thanks in advance for help and suggestions!

While I don't have Cornwalls, my highly modded Klipschorns benefited greatly first from tube amps, both push pull and SET, 300B SET being my favorite pairing. My diy mods to crossovers also major upgrade. I couldn't live without both, but I'd say amp is place to start, whatever crossover mods you do won't be fully realized without the proper amp. Damping of horn is another good mod.

Yes I would say a nice tube amp and some solid copper speaker wires like AQ Type 4. Then work on horn damping and maybe knock down the tweeter if needed. They are not a very warm sounding speaker stock, more accurate than warm. A tube amp with the right tubes will sound very good, system synergy is key. I'm a bit of a broken record but my Rouge Sphinx might be as good as it gets for your system or a really nice tube amp.

First get a good medium powered tube amp. I have heard horns, regardless of sensitivity, eat lower powered SET amps alive. Older Klipsch didnt present the amp with the best impedance load, but perhaps the new speakers are better. 

After getting a good tube amp then explore mods. An unmodified Klipsch is unacceptable to me but with mods they can be greatly improved. Actual Klipsch owners can steer you in the right direction regarding mods.

Thanks a lot for your replies. First amp, then mods then.

Thanks as well for the suggestions! Ampwise I have to take what´s available here (I´m living in Poland) and what I can listen to in advance. 300B I have to check, Rogue Sphinx is sold here. There also is a local brand, which is the one I could test already: Taga Harmony. Their HTA 2500B gave a nice first impression, but well, it was the first tube(hybrid) amp I listened to.

Since it may not be known here I leave a link below.

Per audition_audio, yes Cornwall not as high a sensitivity vs Klipschorns, but Klipschorns do have somewhat difficult impedance curve as well. My 300B monoblocks are sublime, but then they each have power supplies equal or surpassing what you see in stereo 300B amps. My 845SET or any 845SET for that fact should have no problem with impedance curve. Forget about most 2a3 or 45 for Cornwall, although 2A3 with really nice power supplies could possibly work. But for most, I'd agree, go with push pull. I previously had PrimaLuna Dialogue Four, damn nice in triode mode.
