Hi-fi is like cake. Most people enjoy listening to music, and most people like cake.
People who like cake tend to like different things about it. Some people like a flourless cake, some people like a fluffy angel food cake, and some like a cake loaded up with little pieces of carrot and God-knows-what-else. People who like hi-fi also tend to like different things. Some like punchy, forceful sounds, some like realistic, natural tones, some like texture and color, some like "air," and some like to hear things go whooshing from one speaker to the other. It's all okay.
