The vast majority of audio systems, both Hi-Fi and High End, use digital streaming of the music signal. Yes, the magic of vinyl is fascinating, but in many cases in the evening it is much easier to choose a playlist from a streaming service and enjoy Hi-Res sound. However, almost all audio paths oriented to the reproduction of digital, sound can be improved - and the costs of such manipulations will not be too high, and the increase in sound quality can be enormous. In this guide, we will consider the main techniques and steps for improving the sound of a digital audio system.
Software, that is, a player that plays music in the case of streaming, plays an important role. And although we recommend sticking with the industry standard, Roon, it is better to experiment with the results in a specific audio system and compare them with Audirvana and Amarra, as well as with HQPlayer and its connection options to third-party players.
Most digital-to-analog converters only have a USB input, and the signal in the home network is transmitted via an Ethernet connection. Connecting the system via a personal computer is a “bad” solution, as digital noise can ruin the quality of expensive equipment. Well, the Sonore ultraRendu digital bridge has made a real splash in terms of improving the sound quality in a digital system, and the latest version of the device, Sonore ultraRendu Plus, has become even better. This “break” of the path allows you to significantly reduce digital noise and achieve a real increase in sound quality.
The most optimal variant for combating digital noise, which pollutes almost any network, is an optical interface. Many manufacturers have now begun to produce such modules, for example, the Sonore opticalRendu Deluxe bridge or opticalModule is already equipped with an optical interface.
Yes, if you have the opportunity to purchase Hi-Res files, their sound from a local home network will be slightly better than through cloud streaming. Another brick in the foundation of improving the sound quality of a digital audio system.
Roon software uses its own network transmission protocol, Roon RAAT, and Roon's own operating system, ROCK, also shows excellent results in terms of price/quality in this configuration. It can be installed on a third-party server that meets Roon's requirements, or you can purchase a proprietary solution - a server for running the Roon core. Thus, Roon Nucleus Titan shows simply brilliant results.
An audiophile switch is not a joke, but a very serious device for eliminating the notorious interference in a home network. If the cost of this type of equipment (there are already a lot of audiophile switches released, for example, we can note the Synergistic Research Ethernet UEF Audiophile Switch - or the much more affordable iFi Audio LAN iPurifier Pro) seems unacceptable - you can simply purchase a linear power supply for your current switch.
It is the power cables that make the greatest contribution among the "binding" in the digital path. So, the rule is simple - we redistribute the budget available for connectors to this sector and equip all links of the digital path with high-quality power cables.
Another echelon of the fight against noise and interference is network filters and, ideally, power regenerators. We do not recommend using the latter for amplifiers, as they can lose in the dynamics of the sound, but powering a digital bridge, streamer or DAC from a regenerator is a great idea.
Yes, their contribution will not be as noticeable to the overall picture as from power cables - but there will be an impact. Want to avoid such costs? Use the optical network interface, which we talked about above.
As already mentioned, the rule is simple - a home computer or laptop can only be used as a control point. With the same Roon, this is very easy to organize - the Roon control module is located on the PC, and the Roon core operates on an external server.
Amazon Music, Apple Miusic, Tidalm Qobuz - you will be surprised, but different albums and different artists on these streaming services can demonstrate different sound quality, and Hi-Res formats can also differ. So - the more experiments, the better the result.
In the case of using home storage of music data, DSD, especially DSD128 and DSD256, can usually show a slightly better result than Hi-Res PCM.
Conclusion - even in High-End systems (not to mention the Hi-Fi class) you can put the "finishing touches" and significantly improve the sound quality.
Our new buyer's guide and equipment rating is visited by full (with a digital-to-analog converter) streamers or network players. The number of these components is growing day by day, which is why the selection turned out to be interesting - from inexpensive models to High-End class mastodons.
Extra-class floorstanding acoustic systems, Wilson Benesch Omnium – the culmination of 30 years of development experience from the famous British company. The model was created in collaboration after long and thorough research work of the SSUCHY project. The second from the top in the company's range, loudspeakers embodied the most advanced, bold and new sound solutions.
The culmination of decades of research by the renowned Acapella – the complete system (with electronics) Acapella HYPERSPHERE costs 5 million euros, and the speaker systems themselves can be purchased for “only” 3.2 million euros. Well, let’s study the true pinnacle of uncompromising Ultra High-End design.
SAT XD1 is a true pearl of the modern horizon of High End audio equipment. Based on completely rethought engineering solutions of the direct-drive Technics SP-10R turntable, the redesigned vinyl turntable from the famous Marc Gomez amazes with both its sound and price. But, such is the price for truly ultimate quality…
Linn describes its new Linn 360 acoustic systems as a development from scratch, which uses «New cabinet. New drive units. New electronics. New everything». The innovative speakers are truly amazing – both in their appearance and in the large-scale sound, literally breaking our ideas about the physical capabilities of cabinets and drivers of this size.
