In my limited view the Pro Audio requirements are far different from Home Audio Reguirements. Most pro gear is designed far different from Home gear. Most Home gear is designed not to resonate. Most Pro gear is actually encouragedt to induce distortions. From pedals, Heads, cabinets etc.. Also most pro Audio is designed to be mounted in roll around racks. They also tend to be designed to withstand the rigors of being abused on the road and in many cases they can simply swap out output transistors without Elecrically realigning the entire amp. A regular Roadie can handle most repairs of Pro Audio gear. Their ability to handle the rigors of the road and ease of maintence seem to be opposed to how home gear is used.
