KZ D-Fi - The most mature Sounding KZ single dynamic to date....or not!

KZ D-Fi is the latest in the long evolution process of Single DD iems launched by KZ.
From the early beginnings of the CCA CRA with the XUN driver without the conical rear back structure , to the EDA Balanced, onto the Lyra, then CXS and more recently ZVX, the Legendary driver as it has become known, is one of the most well designed DD, focusing on extracting every last ounce of performance from it's design.
The D-Fi is without question a mature sounding IEM, taking advantage of the Zobel network to extract better performance from the midrange frequencies and giving us a very un-KZ sound which is worthy and a true testament to KZs abilities.
