It should be--it costs more than twice as much!
I have an AI clarus head that I use with a couple different cabs-it's really great. But I play a lot with a gypsy jazz band, two acoustic guitars, and whenever I had a bass amp on the floor we had enormous feedback problems. I've taken to putting a powered PA monitor on a stand behind me--I can hear myself perfectly and the guitars don't get driven to feedback, and I don't get weird floor/stage woofs.
I too play a lot with a gypsy jazz group and have had a decent amount of luck keeping the speaker on the floor angled up. When I hoist it up a few feet there is certainly more clarity in the bass on stage, but I guess the beauty of playing in a small drummerless ensemble is the ability to hear everything pretty well acoustically.
I read somewhere years ago (christian mcbride interview maybe) that the way to set the volume on an amp and get a natural stage sound was to turn the amp up until you could hear it, then back it off a bit. In the gypsy jazz setting this seems to be great advice, especially if the guitarists are not using amplification on stage.
