The rods "...confer... the ability to use the given feat a specified number of times per day." Wizards with metamagic feats use them when preparing spells. I would have thought a wizard with a metamagic rod would likewise use it during spell preparation.
But because the sorcerer or bard has not prepared the spell in a metamagic form in advance, he must apply the metamagic feat on the spot. Therefore, such a character must also take more time to cast a metamagic spell (one enhanced by a metamagic feat) than he does to cast a regular spell.
We know that the reason a sorcerer takes a full round action to cast a metamagic spell is because he is applying the metamagic feat on the spot.
We know that because a sorcerer takes a full round action to cast a spell with a metamagic rod, that a sorcerer using a metamagic rod is applying the metamagic feat on the spot.
We know that a wizard casting a spell with a metamagic rod does not take a full round action; therefore we know that a wizard casting a spell with a metamagic rod is not applying the metamagic feat on the spot.
Thus, we know that a wizard casting a spell with a metamagic rod must have applied the metamagic feat at preparation time... which is exactly what the language used by the rod would imply, given that the rod allows him to use the feat, and 'at preparation time' is how a wizard uses the feat.
Which is why I disagree with the FAQ answer in this case.

As noted elsewhere in the FAQ, metamagic feats don't actually alter a spell's level.
However, in the PHB under 'Magic Items and Metamagic Spells', it states that "
Level limits for potions and wands apply to the spell's higher level (after the application of the metamagic feat)."
The explicit ruling is that for the purpose of level limits for potions and wands, the spell has a higher level after application of the feat. The implicit ruling we might infer is that for the purpose of 'Magic Items and Metamagic Spells' - including space in rings of spell storing, pricing for wands of empowered magic missile, limits on Lesser Metamagic Rods, and Pearls of Power - the spell has a higher level after application of the feat.
