The evolution of the AVR spans several decades and is a testament to the constant development, introduction of new technologies, and continuous improvement of the manufacturing companies. A modern AV receiver serves as the central hub of the audio system, it improves the sound quality and we have the opportunity to enjoy high-quality audio and video content right at home. Convenience and ease of customization make it a universal device for any user, and advanced features – impress even the most demanding music fans. In this article, we will consider what exactly determines the quality operation of modern AVRs and what potential they are equipped with today.
High-resolution audio support
High-resolution sound or high-resolution audio (Hi-Res) is a digital format that sounds great and captures the finest details and nuances of a piece of music. Hi-Res is characterized by clearer sound and deeper bass at all volume levels, unlike CD or MP3 formats, which often distort at higher volumes. What distinguishes it from the more compressed audio formats (CD/MP3) is its high sampling rate, which is the number of points of audio data recorded per unit of time, and its bit rate, which is the depth of that information.
For example, the bit rate of high-resolution audio (9216 kbps) is about seven times higher than that of CDs (1411 kbps) and almost 29 times higher than that of MP3s (320 kbps). To fully enjoy High-Res sound, all of the components in your system must be Hi-Res compatible.
As a result, high-resolution audio conveys more sound detail, accurately reproduces soft and loud tones, and delivers more powerful bass, preserving all the subtleties of music. High-Res delivers a wider and more immersive soundstage, making it ideal for audio formats like FLAC, ALAC, and WAV.
Advanced digital-to-analog converters (DACs)
The latest DAC technologies that power today’s AV receivers are the key to decoding high-resolution audio files. They are the ones that accurately convert digital audio data into analog data that is then reproduced by the speakers, delivering the versatility and detail of these files during playback. Looking back, I think how cool it is that today’s technology gives us the ability to fully enjoy incredibly high-quality music, to experience all the subtleties and details of a singer’s signature performance.
Customizable equalizer settings
It is important to apply the appropriate receiver EQ settings. We know that different genres of music often benefit from unique frequency profile settings, so it’s important to intelligently tailor your audio output. Today’s AVR offers sophisticated equalizer settings that let you adjust the balance of bass, midrange, and treble to improve the listening experience for a particular music genre, artist, or recording.
Special music modes
An interesting addition to most modern AV receivers today are special audio modes such as Pure Direct, Jazz Club, Concert Hall, or Arena, which can enhance the music listening experience by customizing sound profiles. By bypassing unnecessary audio processing and equalization, you can easily create the most accurate sound reproduction possible to simulate the atmosphere of a jazz club or give yourself the feeling of being in a concert hall.
Advanced connectivity
Another highly relevant option for today’s AVR is built-in support for popular music streaming platforms such as Spotify, Tidal, Apple Music, and others. Today’s streaming services offer high-quality lossless audio options, convenience, and ease of use. With WI-FI/Bluetooth connections, you can control music playback, search for your favorite songs, and create your playlists using dedicated applications.
Voice assistant integration
Features such as multi-room audio in today’s receivers allow you to divide your home into multiple listening zones, so you can enjoy your favorite music while your child listens to their favorite songs in the nursery. Built-in voice assistants like Alexa, Google Assistant, and Siri do receivers are not only convenient for listening to music but also useful for remote control, giving you superpowers. You can easily control other smart home devices, adjust lights, and even request information without leaving the listening position.
