I use my Beyerdynamics DT770 Pro (80 ohms) for general use and for gaming. I also use a pair of Hifiman HE-4xx when listening to music - from Tidal or from FLAC files.
I was thinking about upgrading the E10K on my desk to something better, say a Fiio K5 Pro or a ifi nano iDSD BL but I am not sure it will really make a difference.
Knowing my (basic) gear, do you think it’s worth it ? And which DAC would you consider buying ?
