Like a lot of things having more knobs is better for people who know what they are doing, for a lot of people,myself very much included it needs to be as simple as possible, thats the only reason to use an old fashioned passive desk but even I've got the hang of the xair. Being able to add in extra matched cabs hired/purchased or borrowed is still too much of a draw to a common but high end brand for me right now but you've got to start somewhere, from small acorns and all that!
