The Sony STRDH190 stereo amplifier offers a well-rounded audio experience with several notable features. With 100 watts per channel and an impedance range of 6–16 ohms, it provides sufficient power and compatibility with most home audio systems. Its low Total Harmonic Distortion (THD) and high Signal-to-Noise Ratio (SNR) ensure clear and high-quality sound output.

For connectivity, the amplifier includes a phono input for turntables, four stereo RCA audio inputs, a 3.5 mm input, and a stereo RCA output, making it versatile for various devices. The built-in Bluetooth feature allows for easy streaming from mobile devices, adding modern convenience to the classic amplifier functionality.

The unit supports A/B switching, enabling you to connect up to four speakers and play them in different zones or simultaneously, which is great for flexible installation setups. The low-profile design fits easily into standard AV cabinets, and its built-in FM radio with 30 station presets and full-size headphone jack add to its usability. The amplifier might not be suitable for those seeking multi-channel surround sound systems, as it only supports a 2-channel stereo configuration. Some users might also find the absence of digital inputs limiting. Despite these minor drawbacks, the Sony STRDH190 is an excellent choice for those looking for a reliable and versatile stereo amplifier for home use, especially if they value the additional Bluetooth connectivity and phono input for turntables.
