Buying Guide for Best Inexpensive 100 Watt Stereo Amplifier
When shopping for a stereo amplifier, especially if you are on a budget, there are several important factors to consider:
Power Output
The power output of a stereo amplifier is measured in watts. A 100-watt amplifier is ideal for driving most speakers comfortably in medium to large rooms. Look for amplifiers that can deliver consistent power without distortion at high volumes.
Impedance Compatibility
Make sure the amplifier you select matches well with the impedance of your speakers, which is usually 4, 6, or 8 ohms. An amplifier with a lower impedance will typically offer more power, but must be compatible with your speaker’s ratings to avoid damage.
Connectivity Options
An ideal stereo amplifier should have a range of connectivity options, including Bluetooth, USB, RCA, and AUX inputs. This ensures that you can connect multiple devices effortlessly.
Built-in DAC
If you want to connect digital devices such as computers and smartphones, consider an amplifier with a built-in Digital-to-Analog Converter (DAC) for superior sound quality.
Size and Design
Consider the physical size and design of the amplifier. Resting space and aesthetic appeal are also significant, especially if you’re setting it up in your living room or entertainment area.
