I get not wanting to stick with Schiit, but it seems to me (both first hand experience, and anecdotal online) that their next level up gear is much more reliable. I have been using as Asgard 2 and Valhalla 2 for several years now, and really can't think of seeing any reports of them dying (not that I've gone looking for them). They also get a 5 year warranty at that level.

If you want to go a different route, the Fiio K5 And K7 are both well regarded, and I liked both quite a bit. JDS is very good and has excellent support, I've never had an Atom, but had a OG El Stack.

Topping seems to have as many issues reported as Schiit and I haven't heard much of their newer stuff, but I didn't think their older stuff (original d30 and a30 and an nx4) sounded all that good.
