The transformers in my CPC catalogue list step up ratios of 1:4 and 1:10.
If the impedances are suitable, etc, that could mean up to a 12dB or 20dB

OK - really not my field (as you probably guessed!) but I thought to
increase the volume you would need to add some sort of power.

I can understand a transformer stepping down a voltage but can't see
how it can step up without losing or altering something else i.e.
possibly decreasing the current. Not sure how that would result in an
increase in volume.

Was it Newton that said 'Yer get owt for nowt' ?

Haven't got a clue what I'm talking about though!

Are you saying that simply passing the o/p from my mp3 headphone
socket through one of your transformers will boost the volume out to
the speaker?
