The Digizoid ZO starts with a small bass boost, and the last setting is mind-numbing. I found the Digizoid ZO to really sound clean, clear, and HUGE!!! The FiiO E11 is an amp with a 2 stage bass boost. It does sound pretty good, but not D:ZO good.
The two definitely sound different but I can't say which one sounds better. Both have things I like in the sound quality. The thing I like most is the Zo's small size. I used two clicks for the ZO. 3 or more clicks starts to sound muddy to me (all of my headphones aren't that bass shy). Did you know that after 3 clicks the other clicks are negligible in a bass boost? I rmaa all of the clicks once and I got only a tiny touch in bass boost per step after the 3rd click, some as little as a few tenths of a dB. I kid you not. So in theory there are only 4 significant bass steps, 1st , 2nd, 3rd, and last (the 4th through last is just one bass step lol).
