I'd go for it. Something like:

Will work, but it's only 34V and has a power rating far higher than you actually need, so you might want to go for a lower voltage (12V) amplifier with a matching transformer or some sort of network. You could probably also just run them off 3.5mm directly and not get awful performance, as they're 32Ω, but you probably do want an amplifier.

At such a low power on each channel, going for a linear amplifier might not be an awful idea, I think you just need a dual op-amp and a few transistors to make something like this image, plus a few resistors on the op-amp for gain reasons. Don't forget the heat sink. There are many more complicated topologies that I'm sure other people here can clue you in to, but this would allow you to throw it onto a ±20V power supply if you had adequate heating.
