Sure McIntosh is High End. At 4 figues for an amp, they are High End. Looking at the build quality, craftmanship and power, there are High End. They are heirloom pieces that can be passed down. But they are just High End.
Because now you have to consider that there is a new class of high end, Uber-High End, where amps routinely go for 5 figures. I'm talking about Boulder, Ayon Tritons, etc. Some of these guys actually make McIntosh look affordable. Wow, maybe someday I will be able to get an amp with those sexy Blue Meters!
