These models are perfect if you are not looking for a reasonably-priced solution and you do not need many functions. I have collected information from official websites and user reviews to help you choose the best model for you.
Be aware that you will have to connect it to a TV screen to perform any setup functions, like setting speaker levels or tuning in ANY radio stations. There are virtually NO instructions in the included manual. Also be informed that it draws over 20 watts while turned off. With TV, sub and cable box it totaled 62 watts 24/7.
AV receiver STR-DH550 with a total output power of 725 W, iPhone and iPod support, with four HDMI inputs for connecting different devices and a through-passing 4K signal, will become the heart of your home theater. Thanks to the HD Digital Cinema Sound system and automatic calibration, you get quality multi-channel sound when listening to music or watching movies.
The Yamaha RX-V377 will make a decent decision as the central control device in your home theater. Not only for iPod/iPhone. You can connect a flash drive to the USB port for music playback or an MP3 player to the AUX port, set the V377 to its AUX channel and you're all good. If your V377 is connected by way of HDMI to your television, you can see on the screen what's on the flash drive, and you can use the V377 remote to control playback.
This AV receiver has 6 channels (5.1) and an output power of 100 watts per channel with a non-linear distortion factor of not more than 0.09%. The model supports 3D video and many multichannel sound systems.
The main advantage of the Yamaha model is Bluetooth interface support, but you need to buy a special device to use it. However, it does not support the FLAC format, which is quite popular today. The main advantage of Sony STRDH550 is the total power output. The main disadvantage is that this device does not support any types of wireless connection.
Therefore, if you need good compatibility and you are not afraid of cables, then Sony STRDH550 is for you. If you do not need the FLAC audio format support and you are ready to spend some additional money on a Bluetooth adapter, then consider buying Yamaha RX-V377.
