How much power (watts per channel) do I need for my speakers?
The required power depends on your speakers’ sensitivity, the size of your room, and your preferred listening volume. Speaker sensitivity is typically measured in decibels (dB) at 1 meter with 1 watt of input power (dB/W/m). A speaker with a higher sensitivity rating requires less power to produce a given volume level. For example, a speaker with a sensitivity of 90 dB/W/m will be significantly louder with 10 watts than a speaker with a sensitivity of 85 dB/W/m.
For small to medium-sized rooms and speakers with moderate sensitivity (around 87-90 dB/W/m), an amplifier providing 50-75 watts per channel is often sufficient. If you have larger rooms or less sensitive speakers, or if you enjoy listening at louder volumes, you may want to consider an amplifier with 75-100 watts per channel or more. Keep in mind that doubling the amplifier power only results in a 3 dB increase in sound pressure level, so a significant jump in wattage is needed to produce a noticeably louder sound.
What is the importance of Total Harmonic Distortion (THD) and Signal-to-Noise Ratio (SNR) in a 2-channel amplifier?
Total Harmonic Distortion (THD) measures the percentage of unwanted harmonic frequencies added to the original audio signal by the amplifier. A lower THD value indicates a cleaner, more accurate reproduction of the sound. Generally, a THD of 0.1% or less is considered good, and anything below 0.01% is excellent. While extremely low THD values are desirable, the audibility of distortion depends on its nature and the listening context. Some argue that distortion levels below a certain threshold (around 1%) are nearly imperceptible to most listeners.
Signal-to-Noise Ratio (SNR) measures the difference between the desired audio signal and the background noise floor. A higher SNR value indicates a cleaner signal with less audible noise. An SNR of 90 dB or higher is generally considered good, and anything above 100 dB is excellent. A low SNR can result in a “hissy” or “noisy” sound, especially during quiet passages or at high volumes. Both THD and SNR are important specifications to consider when evaluating an amplifier’s performance, though subjective listening tests are also essential to determine the actual sound quality.
Should I choose an amplifier with a built-in DAC (Digital-to-Analog Converter)?
