I am too embarrassed to go through a list of all the amps I've loved before, that travelled in and out my door.......
The Quilter amp seems to be getting a lot of love. People are using them to drive Greenboy cabs which can take GOBS of power. Small and powerful. Either take your whole rig to somewhere that stocks them, find a second hand one or buy one on distance selling and mess with it at home/rehearsal and then decide.
Other amps are available.
Perhaps borrowing a PA power amp and rehearsing with it would let you experience increased headroom before shelling out any £. Making decisions without shelling out £ is my favourite thing. Apart from cake, obviously.
