I think for the beginning, I'm running a decent Headphone stack, but I'm looking atm for some improvements. Currently, I'm running Tidal or FLAC Files → Sound blaster Z → Very good coper cable → Shiit Magni + → Sennheiser HD 800s with stock cable. I think my none existing DAC can replace my Sound card, or is some other element in this stack the weak point? I need some recommendations. I went with the HD 800s because I really like classic, ambient music with big soundstages. They are complete stock with none eq. because the most eq. profiles reduced the soundstage.
