Marantz 2-Channel Silver/Gold Integrated Stereo Amplifier With Streaming Built-In offers 0.02% THD and a 106dB CD signal-to-noise ratio. It features built-in Bluetooth and extensive direct streaming support, including Spotify, Amazon Music, Pandora, TIDAL, and Apple Music.
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 $2,500.
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.
