I uploaded Noble Katana review on my JP blog.
http://vaiopocket.seesaa.net/article/441829630.html
Here I described what the Katana is, Who is the Wizard and How Katana sounded.
For English summary, I mainly used AK70(USB out)+iQubeV5 DAC combo as well as Hugo and Mojo.
Katana delivers uncanny transparency and great detail, that makes fading voice strikingly beautiful. Mids and Highs are lush and crystal clear.
Also Katana sports well balanced frequency response with well controlled bass. Actually the Katana delivers extraordinarily sharpness and tight sound on all over the frequency. In addition to that, I feel very wide frequency response with deep bass. The bass is not humped while extend into the deep sub bass.
Katana is fairly honest to the source gear as well as Katana reveals all the sound quality of the gear. I can feel the smoothness of MP filtering on RWAK120, a tactile texture of Hugo and a very low distortion off the digital amp of iQube. Katana is a great reproduction monitor too.
Katana reminds me of the sound of the Tzar350 but far more refined. I think the extra sharpness and the honest sound reproduction has inherit to Katana. It's like a family tree of the reference IEM by Wizard.
When I removed them from my ears, I was impressed again by the compact nature of Katana. This is even pillow friendly.
Katana is a great piece of masterwork and a top notch IEM. As a Japanese, I know Katana - Japanese sword has been made by a few sword masters some of them is a living National Treasure of Japan. Katana sword is not a mere weapon but an art work. Noble Katana is well worth the name.
I will compare Katana with K10 in the next article as well as available re-cable options.
