My current stable is the Z1R on my bedstand, and the Tia Trio in my briefcase. The latter does amazingly well with Tidal straight out of my phone (need foam tips, though, to keep it in balance).
To my ears trio fits better my desired sound signature.
It also paires nicely with wm1z.
Trio is a more fun tuning then z1r.
It has less treble spike also more forward mids, I love the trio presentation its louder and more prominent vs z1r.
I give an edge to z1r on bass layering and textures plus a bit more details.
But trio offers in exchange a bigger slam and if paired with very highend cable it transforms it into refined graphite analog sound, really addictive.
Also trio is a little more thicker and warmer to.
Z1r is for folks who want noble audiophile tuning for classical, jazz, guitars and all live instruments.
But I find it to bright to my liking with wm1z....
But trio fixed my treble spike annoyance and fills the live with edm music better!
They are bothe very high end iems and extremely capable...
I do find trio tia tubeless high treble extension more appealing !
Again with a proper cable and wm1z oh my goodness!
Z1r effect is like small little needles pinching.
Trio is thicker but also have nice zing and decay....
