I listened JAVA HiFI Carbon double shot INtegrated amplifier in the Warszaw AV show.
It was brilliant, the best class D I have ever listened.
Simply I thought I could not return nCore and Purifi
and have to try other GaN FET amplifiers too.
GaN FET is quite awesome. Many have gone this direction, Atma-Sphere, AGD, Gold Note to just name a few. I have the PA-10's from Gold Note in one of my systems and do love them. However in my heart of hearts I am still a tube guy.
