Buying Guide: Stereo Amplifier
📋 Table of Contents
1How much power (watts) do I actually need in a stereo amplifier?
Power needs depend on your room size and listening distance—25-50W works for small rooms, 50-100W for medium spaces, and 100W+ for larger areas or if you like loud volumes. Efficient speakers need less power, so check your speaker specs alongside amplifier wattage.
2What's the difference between integrated and separate amplifiers?
Integrated amplifiers combine the preamp and power amp in one unit, making them space-saving and simpler to set up, while separates give you flexibility to upgrade components individually. Separates typically cost more but offer better sound quality and modularity for serious setups.
3Should I prioritize THD (total harmonic distortion) or impedance matching?
Lower THD (below 0.1%) means cleaner sound, but impedance matching between your amplifier and speakers is equally critical—mismatched impedance can damage equipment or produce poor sound. Always check that your amp's output impedance matches your speaker requirements.
4When is it worth spending more on a stereo amplifier?
Invest more if you have quality speakers that can handle it, plan to keep the system long-term, or listen to music as your primary hobby rather than background use. Budget amplifiers often have higher distortion and limited connectivity, while mid-range and above offer better sound clarity and durability.
5What connections and inputs should I look for?
Ensure it has enough RCA or XLR inputs for your sources (turntable, CD player, streaming device), and check for modern options like digital inputs or Bluetooth if you use wireless devices. Some amplifiers include a phono stage if you plan to use a turntable, saving you an extra purchase.
