I agree with the above. The Ashdown C110 is a cracking little amp. If you find your self in the situation where a bit more power is needed, add a small cab, poss a 15. Otherwise, as said, send the feed to the PA.
The C110 is 300w 4Ohms and is more than capable.
I have one and am looking for a 15 cab for mine. Google through up this post and so I thought I would join up.
