<em>The word that has a neutral connotation would be </em><em>multilevel. </em>
Explanation:
Connotation is the associated or secondary meaning of a word or expression in addition to its explicit or primary meaning. Multilevel in any definition would not relay any good or bad feeling to it.
Secondary source is more like say you were at home and your friends tell you about a Party in the phone he's giving you information since it weren't there
