Quad Driver In-Ear Headphones

Oh man... I did the same stupid impulsive sell (got Tea Pro SE and sold the OG) and now I regret it and want to sell the SE and get the OG again :). Can't do the comparison (have the Dusk, don't have the Tea Pro) so take my words with a grain of salt. I'd say it depends on the source gear. If you plan on using Dusk with the DSP cable, you're safe. The treble is a bit smooth and rounded, but it has a shit ton more upper treble than Tea Pro. On higher end (clinical sounding) gear though, the tweeter planars are definitely adding more spice. Tea Pro has audibly more lower treble and it's more "contoured" and exaggerated, but in a very pleasant and incisive way. At the same time, it lacks upper treble shimmer. So treble-wise, it totally depends on where you might or might not be sensitive, what you like, and how your anatomy influences the treble actually sounding to you in IEMs. Dusk is definitely the more natural and neutral sounding (apart from the sick sub-bass boost), but it presents sounds in a very clean, separated way with enough body to not sound clinical. It's fun but very well balanced and technically impressive. It's not the most cohesive set, but that might actually be a good thing. It makes tones very distinct and well separated. Tea Pro is just more fun overall. It's not as technically impressive and doesn't separate tones as well, but it's just more fun. I'm not sure what's going on with the treble exactly. On lower quality sources I had some issues with it, but on more resolving ones it got better and smooth. (Same thing with Tea Pro SE.) No idea what that's about. I think Dusk is overall outstanding, but what I hear as smooth extension you might hear as copious amounts of unnatural treble. No way of knowing without auditioning the set. Seriously, reviews or graphs say shiiiiit about how it will actually work in your ear.

Your preferences are same as mine... I had tried most of the IEMs you listed... I was really in love with my Tea Pros... I happen to hear QOA Mojito and I sold the Tea Pro because Mojito was smoother than Tea Pro... Now, I miss the fun factor of Tea Pro and also miss it's wider sound stage... If I had kept Tea Pro a few days more then I would have never sold them... It was an impulsive sell..  I'm now planning to buy Tea Pro again... I also have an urge to try Crinacle dusk... How would you compare Dusk DSP with Tea Pro?  If I had to tackle the slight spicy presentation of Tea Pro on some tracks then is it ideal to choose Dusk?
