What would be a decent desktop amp or dac/amp to power these properly?

Fantastic to hear, thank you.

Is anyone here using the amp Topping A30 with these headphones? How does the 10 ohm output impedance affect them?

Has anyone tried this with t50rp's (Argon's more specifically) and noted any changes in the sound for the worse, being 50 ohm headphones? Then again they are planars and hard to drive so the output impedance might not have much effect. I'd love to know since I'm trying to decide between this...
