KZ‘s 10th anniversary model, a new product line ESX, self developed 12mm LCP DD backed arrived!
▶︎OOTB, it reminds me of CRA+’s performance, wow great. CCA CRA uses 10mm and this ESX uses 12mm, ultra thin liquid silicone diaphragm KZ claims.
▶︎my pair‘s stock cable got a nice smell of farm land (livestock’s smell), I know why… when I attended some audit of my company, the raw materials (wires etc) were stored at warehouse full of

and it’s next to a farm land. Same thing happened to this cable
▶︎ESX’s LCP falls slightly behind a DUNU Titan S, or HOLA class right out of the box, but it has deeper bass and more energy
▶︎Tuning is focused on macro energy, upper mid focused, spacious expression focused Gorilla.

When you compare ESX with Timeless (Crinacle rated as “Neutral with Sub-bass boost” and Thieaudio Elixir) ESX has slightly higher Gorilla power on lower bass shelf, but rest of spectrum is pretty similar.
▶︎Interesting throw from KZ, it was only recent that their single DD reached to driver with treble detail articulation capability
▶︎Transient response is that of LCP, slightly less focused than Aria, but that’s current state, LCP type generally has poor performance right out of the box
▶︎Timbre is organic, probably best of KZ/CCA. Worth to claim it as 10th anniversary.
@PhonoPhi Thanks to bring ESX on my radar! It has what it to claim as KZ’s LCP. I will burn-in to see if ESX would come up to Aria / Titan S / HOLA class!
I’m glad to know KZ now has capabilities in LCP arena as well, KZ should re-challenge MST+BA+SPD+LCP… After numerous beta test with their try and error, KZ certainly is learning, about a time to come up with fun challenges
MST for UHF, BA for HF, SPD for MID, LCP for bass.
