Pretty sure the question was about two specific products by Auralic and Innuos. Not 432evo, despite the dealer bringing that brand up again.
Anyway back on topic, I compared these exact two products (among many others) a few years ago and my choice was the Zenith mark III. Auralic was very nice and I liked it better than some of the others, would probably have been happy enough if I got that instead. But with direct comparison I felt the Zenith had better synergy with my system.
I'll upgrade again in a year or two. By then both brands will have newer models (I think they do already) so it might end up differently.
