The fact that you have Klipsch on your prefered list indicates to me (at least), that you value high efficiency and, perhaps, have some level emotiional attachment to the brand and/or vintage American nameplates. All valid reasons for choosing what to place in front of you in your listening space.
I’m not sure how adventurous you are, but if you’re leaning in the direction of Klipsch, please note there are significant sonic improvements to be gained with some simple upgrades/tweaks. If you love the Klipsch, but would like a bit more "polite British loudspeaker" flavor to them, you can have both. There’s plenty of info out there if you are interested. We’ve been doing Klipsch mods for decades and the gains can be pretty spectacular.
I agree with @glennewdick that it’s hard to beat the sound quality of high efficiency speakers at lower volume levels. Having some simblance of dynamic range, detail, and bandwidth at levels just above the threshold of hearing is sight to behold. Just substitute ears for eyeballs and you’ll get the idea.
Related to the internals: We’ve drilled down pretty deep into speaker guts for a while now. Admiittedly, our experience gets off a few exits before six figure monoliths, but we’ve universally found that when more money is invested in parts (including cabling), sound quality improvements range from incremental to <insert expletive here>. I’d also like to note that there are other factors, such as cable termination methods, that matter -- a lot. Applying "tweaks" to a speaker that you consider a masterpiece in it’s factory form may result in the speaker more endearing to you. Or, it may not. It will sound "different". Whether you’ve made it sound "better" or just painted a mustache on the Mona Lisa is highly subjective.
