Were you able to hear the Atoll by chance?
I never did hear either one. I bought on the advice of members on here. I had my own thread. I dont have a store near me that carries any of these brands, so I ordered from that place in CA.
Is the price the same on the Atoll as Lumin? If price is the same, then I'd compare the DAC stats and other components to at least see which is better on paper. The Atoll looks more fancy with the screen and app. I think if it's price is the same then perhaps the DAC and other components aren't as nice as the Lumin. The display and app on the Atoll are certainly better. I'm more interested in sound quality.
The Lumin is more barebones, and perhaps you're paying more for sound quality. If the Atoll has a DAC and other components as good as the Lumin and costs the same or less then id buy that. I didn't look at the Atoll at all because nobody mentioned it in my thread, at least I don't remember it. There were some others I compared but I can't remember their names!
