Ifi make some excellent sounding wired headphone amps, I have compared it to my Metric Halo Labs ULN-8 3D headphone amp and my Avid Omni (Black lion Modded) headphone amp. Both of these are DACs and Headphone amps. So it’s hard to know what is contributing to what part of the sound…
I prefer Gryphon over both of those.
