Got my Kato the other day. Some initial impressions from an inexperienced listener...
Day 1.
Been listening to KZ ZSX the day before to have a point of reference. When I unpack the Katos they look so small. But are so heavy. Overall, the look is awesome!
Sound-wise, from the first minutes, Kato gives an immediate impression of more refined mids and treble, bass also, but not as apparent. At first got a little of "where are all the highs have gone?" feeling. I guess this is the difference between "cheap" shouty highs (upper mids?) and "refined" ones. On the other hand, this "lack" of highs lets you turn up the volume a little and enjoy the full spectrum of the music. After an hour or so there is no feeling of lack of highs anymore. What is also apparent is hearing new details unheard of in ZSXs, but mostly these sounds are various rustlings, fizzling, riffles and other record artifacts that don't seem to add value to the music, so not sure if I can call this an improvement
So first-day impression of the sound is "WOW", money well spent. I'll see how long it remains ))
A note on the fit & comfort though. Been a while since I unpacked a pair ofo IEMs, but I am pretty sure I usually take the M tips first and get a fit with those or L ones. The L spring tips here are a tad too small. Due to the weight of the IEM, one was getting out of my ear when I moved etc., so I only found a good fit with the foam L ones which feel a bit unusual though. The hooks are softer than KZs as well. Overall, it's much more hassle to get these on. With KZs (and TFZ kings) I just get them in and they're in the right place naturally, in pretty-much a single move.
Day 2.
As I get through more tracks I get a better impression of the sound signature. Which I would describe as "delicate". Or should I say "thin"?
I've switched between my TDA1543 DAC with Cayin HA-2i and Cayin RU6 (NOS mode) and found liking the latter more.
After a while, the engagement in music got reduced... fatigue? You know, this feeling when you're not really happy with the sound and are looking for ways to "improve" something... Then I remembered about the interchangeable sound filters. Switched from default Steel ones to Brass. Nothing apparent changed in the sound signature, but the enjoyment was back. As usual, brass is better for sound than stell
Not sure if from the change in sound or from "doing something to improve the sound". We'll see.
Day 3.
Day 3 is starting today, I'll see what it brings.
