I agree. How may years would you give MQA to reach mainstream levels? I would expect it to take a hardware purchasing cycle to really take hold (not sure what hardware though could be phone or main source in house) that is I don't think the mainstream will rapidly buy new equipment for this. This will be compounded if the tracks aren't equally priced as I doubt many people will buy a more expensive enhanced track if they're not going to hear the benefits for 7 years.
