Blackening Stainless Steel + Stainless Steel.
9iNE-S with all stainless steel housing.
The body part is blackening “Gen” and the back plate part is machined stainless steel.
The combination of black and silver is austere though they are the same stainless steel.
The sound is the finest among the 9iNEs and has a sense of resolution.
The sound is especially thin in the mid and high frequency range, which makes the overall sound smart and gives the impression of a wide space.
The sound is a bit distant, especially in the mid-range, and I think it is the type that makes you listen with spatial expression rather than power.
