The Tian is really, REALLY good. A big surprise at early 2024. An iem I would actually recommend to fellow watercoolers. Priced at ~$900 this is actually a killer.
It equips a U-shaped sig with impressive technicalities. Bass dives deep while being tactile; Mids are full and rich, sounding natural but not too analog; Highs are vibrant and extended, giving an excellent sense of space and air. If I have to nitpick I'd say treble gets very occasionally sharp, but guess this depends on person. Even a treble-sensitive person like me have no problem putting them on for extended periods.
I would describe Tian as an all-rounder that does well among different genres. 80s pop? Check. Electronica? Check. Orchestral? Alright maybe not the best but yeah, check. It is quite forgiving as well, which sounds awesome regardless of recording quality.
Stock cable seems to be your usual copper cable: it feels supple and soft. SQ is decent though, bringing out what Tian intends to deliver. Of course cable swapping gives Tian more room to express, but I don't think that is something necessary. Power is the key though. This iem is POWER-HUNGRY, probably due to its magnetostatic drivers. Despite sounding sufficient on low-power sources, with an extra amp headstage is out-of-your-head, and details keep popping up in an extremely dark background. Basically not something one would expect at this price. Andro 2020 comes to my mind when we talk about top-tier technicalities at ~$1000; Tian outperforms it while giving much better dynamics.
In short, Tian is a killer, thumbs up to Nico @ Gaudio. It does everything well, from tuning to technicals. Guess we have another all-rounder since UM MEST variants. We have ~$9000 iems this day, guess a ~$900 iem is at least worth your demo.
