Hisoundfi posted a great review over on Head-Fi of Noble Audio’s Katana IEM. This along with other reviews place the Katana amongst the top of IEMs available today. As a K10U owner, the differences sound interesting but not worthy of an upgrade from the K10. I’ll make a note to take a listen of the Katana at the next meet.
Pros: Incredible combination of detail and musicality, Extension and transients, Meticulous design, Excellent co-flagship option along with Noble K10
Cons: TOTL asking price (worth it if you can swing it), Unforgiving with poor recordings/sources, Not for those looking for warm and smooth sound
