Sony STR DH520

Today we will be looking at a classic budget AV receiver which has a decent amount of positive user reviews but when it comes to the experts, not so much. Compared to modern AV receivers, the Sony STR DH520 does lack a lot of features. If you are aiming for the latest 3D audio formats, we suggest you look elsewhere.

It is no surprise the sound quality of the Sony STR DH520 is not comparable to the current AV receiver models. The missing Dolby Atmos probably will turn some people away. Still, we can’t ignore the fact of how affordable this Sony AVR is and it has quite a lot of power for the price. You might want to get good speakers to match this Sony STR DH520 as the AVR’s high registers can be unclear at times. For casual listeners, the audio delivery for both music and movie should not be an issue.

The bass performance of the Sony STR DH520 is considered subpar for today’s standard and lacks control. It is not agile enough to keep pace with busy passages and might muddle the higher frequencies. The low frequencies lack details but it has no problem giving a punch. To improve the situation, you can try going for a sealed cabinet subwoofer instead of a ported model. A ported subwoofer has high bass outputs and might deliver overly exaggerated low-end performance due to this Sony AVR sonic characteristics.

It does however lack the kind of excitement which a ported subwoofer can provide for its users due to the lower bass output.
