Understanding Amplifier Classes & Technologies
Amplifier classes – A, B, AB, and D – represent different operational approaches impacting efficiency, sound quality, and heat dissipation. Class A amplifiers, while offering the purest sound due to constant current flow, are notoriously inefficient, generating significant heat and requiring large heat sinks. They are less common in bedroom setups due to power consumption. Class B amplifiers are more efficient but suffer from crossover distortion, a noticeable imperfection in the audio signal.
Class AB amplifiers represent a compromise, combining the linearity of Class A with the efficiency of Class B. They are the most prevalent type in modern bedroom amplifiers, offering a good balance between sound quality and power usage. Digital Class D amplifiers, increasingly popular, utilize pulse-width modulation (PWM) to achieve high efficiency and compact size, often found in all-in-one systems and smaller desktop amps. While early Class D designs faced criticism for sound quality, advancements have significantly narrowed the gap with traditional analog classes.
Beyond class, technologies like discrete component design versus integrated circuits (ICs) influence performance. Discrete amplifiers, built with individual transistors and resistors, are often favored by audiophiles for their potential for superior sound, allowing for meticulous component selection and customization. However, they are typically more expensive and require skilled assembly. IC-based amplifiers offer cost-effectiveness and reliability, utilizing pre-designed circuits for consistent performance.
The choice between these technologies depends on budget and sonic priorities. For critical listening, a well-designed discrete amplifier might be preferred. For everyday use and convenience, an IC-based Class AB or D amplifier provides excellent value.

Wi-Fi connectivity, often integrated with multi-room audio systems like Sonos or HEOS, enables streaming from network-attached storage (NAS) devices and online music services.
Compatibility with different speaker impedances is another critical consideration. Most amplifiers specify a minimum impedance (typically 4 or 8 ohms) they can handle. Connecting speakers with an impedance lower than the amplifier’s minimum can damage the amplifier. Speaker output wattage should also be matched to the amplifier’s power output to avoid distortion or speaker damage.
Finally, consider the presence of a pre-out connection. This allows you to connect the amplifier to a separate power amplifier or subwoofer, expanding your system’s capabilities. A headphone output is also essential for private listening, and its quality can vary significantly between amplifiers.
Power Output & Room Size Considerations
Determining the appropriate power output for a bedroom amplifier is directly linked to room size and speaker sensitivity. A smaller bedroom (under 150 square feet) typically requires less power – 20-50 watts per channel is often sufficient. Larger bedrooms (150-250 square feet) benefit from 50-100 watts per channel, providing headroom for dynamic peaks in the music. Beyond 250 square feet, consider amplifiers with 100+ watts per channel.
Speaker sensitivity, measured in decibels (dB), indicates how efficiently a speaker converts power into sound. Higher sensitivity speakers (90dB or greater) require less power to achieve a given volume level. Conversely, less sensitive speakers (85dB or lower) demand more power. A general rule of thumb is to increase amplifier power by 3dB for every 10dB decrease in speaker sensitivity.
It’s important to understand the difference between peak power and RMS (Root Mean Square) power. RMS power is the continuous power the amplifier can deliver without distortion, and it’s the more relevant specification. Peak power represents the maximum power the amplifier can briefly handle, but it’s often inflated and doesn’t reflect real-world performance.
Overpowering speakers isn’t necessarily detrimental, but it’s inefficient and can potentially damage them over time. Underpowering speakers, however, leads to clipping – distortion caused by the amplifier reaching its limits – which can severely damage tweeters. Careful matching of amplifier power, room size, and speaker sensitivity ensures optimal sound quality and longevity.
