Match your amplifier's power output (Watts RMS) to your speakers' sensitivity and impedance (Ohms). Do not obsess over astronomical peak wattage claims; RMS is the true measure of sustained power. Available from $2,749.95.
Amplifiers have practically zero ongoing costs aside from electricity, which is highly variable based on usage volume and class type (Class A uses more power than Class D). Good amplifiers can last decades with proper care. Consumables are virtually non-existent unless using tube amps.
Common Failure Modes
Solid-state amplifiers are extremely reliable. Failures usually stem from blown capacitors, overheated output transistors, or physical wear on volume potentiometers. Proper ventilation prevents 90% of heat-related failures.
Match your amplifier's power output (Watts RMS) to your speakers' sensitivity and impedance (Ohms). Do not obsess over astronomical peak wattage claims; RMS is the true measure of sustained power. Class D amplifiers run cool and are compact, while Class A/B offer traditional warm sound at the expense of heat and size.
Solid-state amplifiers can last 20+ years. Capacitors may eventually dry out and need replacement.
