Mini amps take advantage of the miniaturization and vast reduction in cost of audio equipment. You can get a quality digital sound card for super cheap, and it can be really small. That’s led to a proliferation of mini amps: they include just the basics, they’re tiny, they’re cheap and yet they sound astoundingly good. Even audiophiles rave about the sound you can get out of these things. There’s no contest, comparing a setup with a mini amp to a Bluetooth speaker or soundbar: a mini amp stereo system will create louder, richer, deeper, clearer sound, every time.
