Won't people think I'm crazy for buying a tube amplifier?

They might, yes. They may say, what's wrong with having the same plain old solid state amplifier that we have? You know, the black plastic one made by robots in a factory somewhere. What do you want with a 2-channel hifi music amplifier when you could have a 5 or 7 channel home theater amplifier and spend your spare time watching movies and listening to breaking glass and thundering sound effects on your subwoofer? Who even has a tube amplifier?

Or, maybe they will see it and be curious like you are, and ask you to tell them about it. And you can slip an album out of its cover, click the amplifier on, and show them how an invention nearly a hundred years old can be made by hand in a modern interpretation, can produce incredible and authentic sound, and look beautiful in your home, and you can explain why you love analog.
