I have the Atom amp and have been enjoying it. I also have the Argons on order. I noticed a reddit thread that said that Ryan at modhouse has an atom amp for his argons. I still am tempted to get a THX, either monoprice/789/SMSL. The question is.... do I really need that much power for the Argons? I currently have m1060c, LCD2, x2HR, campfire, JH 13v2 in ears. I still have my eyes on the T1, mid level Hifiman, ether cx, maybe the Sendy aiva, 1990 pros. So I don’t mind future proofing, but damn the Atom seems so nice. Oh, and I have a topping D30. If there really isn’t a NEED to power the Argons, I am plenty happy with the Atom.
