A good stereo receiver is a core component of a basic hi-fi system, and if you're just getting started it can be hard to figure out which to choose and how much to spend. But for Prime Day, the stalwart Sony STR-DH190 is on sale for under $100, and a no-brainer for any buddying audiophile.
With Bluetooth capabilities, power enough to get your speakers going, and a preamplifier for a turntable, it has everything you need to get started, letting you spend the rest of your budget on the more important parts. And at under $100, it's a steal.
