Well, since there's been all this discussion on the coloration thing:
I don't go seeking colorations per se. In fact when I evaluate speakers and gear I'm usually listening for a lack of (perceived) coloration. I don't want to be too aware of a speaker imposing it's coloration on the sound!
Among my favorite speakers I've had in my home were the Waveform Mach Solo speakers. They were measured for a review in, I believe, the Audio Ideas Guide and they found the speaker to measure extraordinarily well - super flat across the frequency spectrum with good off axis performance. They sounded very "good studio-monitor-like" and I loved them!
The last bunch of speakers I've owned - Thiel 3.7, Harbeth SuperHL5+, Thiel 2.7 and Joseph Audio Perspectives may not measure as textbook as a Revel, but they also aren't exactly abominations of coloration! (Even the Devore O/96 speakers I often cite are actually pretty even on axis).
The only reason I will often bring up Devore speakers, or my tube amps, is because they are convenient examples of gear that doesn't measure in what most here would consider "best practices" in design, but which I nonetheless find compelling, sonically. I also like many other speakers!
I don't "seek" coloration but I'm ok IF a component introduces some coloration IF I happen to perceive that it enhances the sound in some way I like. I did find the character of the Devore speakers to enhance the "feeling of live sound" vs many other speakers I listened to. On the other hand, it could also sound more "speakerly" with some stuff - that is a sense of the sound coming from big resonating boxes. It was a weird back and forth - mostly I found whatever coloration was there to be quite cannily integrated so I didn't notice it. But I noticed some issues enough that I ultimately went for the Joseph Audio speakers, which sounded to my ear less colored in that respect. It could be that if I'd bought the Devore I'd acclimate so any coloration. Or it could have been it would be come more and more obvious and annoying over time. I didn't care to take the chance, especially without a home audition.
(The proposition that imperfections in the Devore design would *necessarily* become annoying over time isn't necessarily born out by user experiences. It seems the vast majority of O/96 speakers express utter contentment years after the purchase, the O/96s don't show up often in the used market relative to their popularity, and the O/96 sell faster on the used market than just about any other speaker).
As to the idea that, enjoying some level of coloration would therefore entail someone would need
'a different set of speakers for different genres of music' or that it would
'smother the differences in recordings' I find that quite overblown.
As I've said, in regard to the slight distortion from my tube amps (presuming for sake of argument that is what is happening), the only reason I have kept the amps for 20 years is because they sound good with ALL genres of music. For me it (slightly) enhances almost everything.
And even the Devore speakers were far from being only good with one genre or making everything sound similar. Recordings utterly changed quality - in just the way they did on plenty of neutral speakers. And I found that their palpable, propulsive, weighty presentation sounded wonderful for every genre of music I threw at them, from classical to jazz to pop, heavy metal, electronica etc.
YMMV of course.
