We are in the digital age and innovation has already given us phones, computers, iPads, etc... that are smaller, more lightweight, and much more powerful in their usefulness. This is also happening in audio and is inevitable. It will take time, but the early adopters are now giving way to early majority. It is happening right now before our eyes! The life cycle has already started. There will always be laggards that will not give up what they know and love, but make no mistake the cycle is well underway.
As has already been pointed out, most manufactures are now making Class D and digital amps. These were not available from most of these manufacturers just 10 years ago. The cat is out of the bag and much effort, R&D, and general resource funds are being poured into improving the technology. This is not a fad, rather it is disruptive in nature and will reach wide scale usage in the future. Yes it will take time, but in the big picture 10-15 years is not very long.
