People spend thousands of dollars on stereos. Sometimes tens of thousands. There is a specialist industry right here in the States which builds stereo gear to a standard you wouldn't believe. Tubed amplifiers which cost more than a house. Speakers taller than me. Cables thicker than a garden hose. Some army guys had that stuff. I'd heard it on bases around the world. Wonderful. But they were wasting their money. Because the best stereo in the world is free. Inside your head. It sounds as good as you want it to. As loud as you want it to be.

They were asking for whatever they got. His response was their problem. But dogs were different. No free will. Easily misled. It raised an ethical problem. Shooting a dog because it had been induced to do something unwise was not the sort of thing Reacher wanted to do.
