About Amplifiers & Preamps

An amplifier is the engine of any speaker-based home theater or stereo setup, taking a line-level signal and delivering enough current to drive your speakers to room-filling volume. Preamps sit upstream, controlling source selection and volume before the signal reaches the power stage. The two functions are sometimes combined in an integrated amplifier, sometimes kept separate for flexibility or sonic reasons. Budget 2.0-channel amps from brands like Pyle and Moukey bring Bluetooth and USB inputs for well under $50, making them easy upgrades over TV built-ins. Mid-range options add more headroom and cleaner Bluetooth stacks for $80 to $150, while streaming-ready integrated amps from WiiM and Dayton Audio close the gap between traditional hi-fi and whole-home audio at $300 to $530. At the top end, audiophile-focused units from FiiO and S.M.S.L emphasize low-noise signal paths and high-resolution inputs, and commercial multi-zone amps like the Dayton Audio DAX88 handle whole-home distributed audio. Picking the right amp comes down to three numbers: how many channels you need, how sensitive your speakers are, and what sources you plan to connect.
