McIntosh amp taps vs current

It does. Every active amplifying device, tube or transistor, has a safe operating area, or SOA. The McIntosh autoformers allow the output transistors to always run inside their safe operating area by matching the speaker load to the amplifier.
Also, every amplifying device has an optimum linear operation point, allowing for the lowest distortion with the least amount of negative feedback and generating the least amount of heat.
Autoformers allow the output devices to run in their most linear range.
