A few questions about output capacitors on my headphone amp.

My first headphone amplifier consists of a multiwatt chipamp to which I had to reduce the gain and increase the input impedance in order to have any kind of meaningful volume control available.
The circuit has two output capacitors of 2200uf each. Given the small amount of power that the amp delivers (relative to its original design), can the cap value be tweaked to improve the dynamics (theory being that smaller caps have less lagtime)? I could do this swap pretty easily, but if there are hard-and-fast rules about output caps, I'd rather find out first.
Second question: what about subbing the caps for transformers, like is commonly done on tube amps? Maybe using small stepdown transformers could allow me to decrease the input impedance? The same DC-blocking intent of the caps is achieved with transformers, correct?
I probably need to clarify other points about the amp and its circuit, but for now, I'll see what the gurus say.
The amp is powered by a 9-volt battery and my headphones are 32ohm.
Much appreciated!
