Long story sort I wasn't paying attention and plugged a single ended 3.5mm cable into the 4.4mm to 3.5mm adapter I use on my Zen Can. How likely is it I have just damaged the thing? It is currently still working,

It’s not a guarantee that you will hurt the amp, just a likely possibility. If it is still working and playing fine, then I’d say you probably did no damage.
