I basically can't decide between the HD6xx, the AKG K7xx and the DT880 600 ohm.
I have a Grace SDAC and a Darkvoice 336SE tube amp.
Source is mostly Tidal via usb to the SDAC.
I prefer alternative rock, metal, and classic rock, but also listen to a fair amount of of classic jazz and swing.
I like a "warm" sound, but don't want to sacrifice accuracy.
