If I may play devil's advocate here:
Are these DCs really that bad? Sure, they're not that hard to overcome, but consider:
1) Is the DC for a regular fireball much better? Only by virtue of the presumably higher intelligence of PC wizards. Why should the staff of the magi shoot fireballs that are so much better than what wizards normally cast?
2) It's a save for half damage, so even if they make it, they're taking 5d6.
3) Even if it seems underpowered for a high level character, it's still an item with a unique combination of spells that can be recharged by any wizard, without an item creation feat, so it's still very powerful in the eyes of lower level characters.
(Aside: Can any character use this item fully? Since it's not specifically described as a staff, but as an artifact, is there no requirement to have spells on your spell list in order to use it?)
Devil's advocate arguments aside, I'd recommend changing the DCs with some rationale. For instance, one simple idea is to assume that the creator(s) had a high intelligence (at least 18) whose modifier is added to the DC. Or you could say that all spells cast from a staff of the magi are considered to have Spell Focus.
(Another aside: I can't find any rule specifying the DC of a wand or staff. Does it actually say somewhere whether the DC for a spell cast from a wand is the same as if it were cast by its creator, or by its wielder, or simply the minimum DC for any caster?)
