I’m new here but I would encourage you to try some devices by borrowing from friends, listening in shops with the headphones you plan to use, before buying.
I own a dragonfly cobalt, chord mojo and Hidizs S8. I can barely hear any difference between them. They all sound good to me, so with hind sight I would have just bought the Hidizs s8 and saved a lot of money.
Cheers
