Not so long ago I had the opportunity to compare two models of receivers. It could be difficult to choose the best receiver because Sony STR-DH790 is compatible with other gadgets, while STR-DH770 produces a great sound quality. So, I decided to write this comparison to discover the main differences between these products.
First, I would like to admit that Sony STR-DH790 is more powerful than its competitor because it maintains different audio formats (AAC, Apple Lossless, DSD, FLAC, MP3, WAV and so on), while Sony STRDH770 is able to produce MP3, WAV, and WMA. I do not want to waste a lot of time to find the appropriate disk. On the other hand, Sony STRDH770 consumes only 240W, while Sony STRDH790 requires 700W.
Sony STRDH790 has 7 built-in decoders, that’s why I can watch high-quality videos and enjoy the pure sound. Unfortunately, Sony STRDH770 maintains only Dolby True HD and Digital Plus. Both of these devices are able to maintain the Bluetooth signal, but you can forget about WI-FI. In addition, the developers didn’t add a special smartphone remote control function.
As for the design, it is difficult to choose the winner of this battle - Sony STRDH770 vs STR-DH790. I think that Sony’s designers are real geniuses and most of their gadgets look great.
The front side is very stylish and you can find input selector, volume and several buttons, which can help you turn it on/off, add speakers, tuning modes, night mode, Bluetooth and so on. Materials are high-quality and it’s a real pleasure to touch it. As for the back side, it is like a paradise for sound lovers: dozens of different ports, which you can use to get the best user experience.
