For quite some time my favourite combo was Empyrean out of A&K Kann Cube. I was using a Forza Audio Noir Hybrid HPC between them.Give me an example please
I really loved that sound.
At some point I bought a Hiby R8. It had more linear sound than the Cube, and had more power. It was also more convenient to use it because it had a faster UI and was much faster ready after turning it on. But there was a problem for me - it had so strong punch at certain drum hits that it was causing pain in my ears, even when was not set extremely loud. I tried to mitigate that using low gain and no turbo.
At once the Forza HPC cable started to fall out of the HP sockets randomly due to some issues with the latching mechanism.
I bought a Norne Audio Vygarde (also copper and silver hybrid) cable out of curiosity. The strong punch painful hits were gone, without any significant change in other aspects of the sound. I could use high gain and turbo as well. From that moment I am mostly using the Norne cable. I have not sent back the Forza for repair (yet).
