Tonally NCF is similar to Oyaide R0 or R1. ( with R1 lighter and more sparkle ). But Furutech GTX sounds rounder , while R Series are very sharp. This is clearly audible On distorted electric guitar of heavy metal. Where I slightly prefer Oyaide, it sounded as if electric Guitar were plug direct to my brain. Also sound of gun operation, swords hitting each other during movie. Oyaide will make it so exciting. Thats why I installed Oyaide R0 besides NCF on the same circuit,but as a secondary outpet that I can use it when I want to have sharper sound.
