What Happens to Hi-Fi When the App Disappears?

When the most vulnerable component in a modern audio system is no longer the capacitor, but the software.

Imagine a network amplifier with a perfectly healthy power supply, fully functioning output stages, a faultless DAC and not a single burnt or worn-out component inside. Yet it cannot play music. The app no longer finds it, the controller can no longer be installed on the old phone, and the new phone does not support the earlier version. Electrically, the unit is operational. In practice, the system appears unusable.

Only a few decades ago, this situation would have been almost impossible to imagine. An amplifier switched on, the input selector changed sources and the volume control acted directly on the signal path. When something failed, there was usually a measurable cause: a defective semiconductor, a dried-out capacitor, an oxidised switch, a worn mechanism or a cracked solder joint.

Modern hi-fi has added a new and largely invisible group of components. It includes the control app, firmware, network protocols, cloud services, user accounts and authentication systems operated by external streaming providers. None of these can be seen when the lid is removed, yet any one of them may prevent the music from playing.

The question is therefore no longer simply how long the electronics will last. We must also ask how long the digital world surrounding the product will remain alive.

The hi-fi signal path is longer than we think

The operating chain of a conventional analogue system is relatively easy to follow. A turntable or CD player sends a signal to the amplifier, which then drives the loudspeakers. Plenty can still go wrong, of course, but the purpose of each component and the connections between them remain clear.

In a modern networked system, the journey taken by the music can be considerably more complex. The app on a phone discovers the player on the local network, communicates with the manufacturer's back-end systems and passes the selected content information to a streaming service. The player authenticates access through the internet, receives and decodes the data stream, applies digital signal processing or room correction where required, converts the result into an analogue signal and finally plays it.

Each part of that chain can create a separate dependency:

• the operating system of the phone or tablet;

• the current version of the control app;

• the manufacturer's servers and user-account system;

• the login and authentication method used by the streaming provider;

• the structure of the home network;

• the player's firmware;

• the supported codecs and network protocols;

• and the validity of its security certificates.

The more services a manufacturer integrates into a single product, the more convenient that product may become. At the same time, it becomes dependent on more systems over which its owner has little or no control.

What does the app actually do?

It is easy to think of the app as a simple remote control. In many modern systems, however, it does far more than adjust the volume or select a track. It may be responsible for:

• initial setup;

• network configuration;

• adding streaming accounts;

• selecting inputs;

• creating multiroom groups;

• configuring room correction;

• installing firmware updates;

• and even accessing essential sound settings.

If these functions have no equivalent physical controls, browser-based interface or alternative control method, the disappearance of the app can mean more than a loss of convenience. It may result in the partial loss of the product itself.

This is particularly important with integrated active loudspeakers and all-in-one systems. When a component fails in a conventional system, it is often only that individual unit that drops out of the chain. In a fully integrated design, the same central electronics may control streaming, source selection, volume, the crossover, the amplifiers and the protection circuits. If the digital control layer becomes inaccessible, the usability of the entire system may be affected.

The external service changes even when the player does not

A network player is not a closed product. It connects to services that change continuously. A streaming platform may alter its login process, retire an earlier programming interface, introduce new encryption requirements or discontinue an older codec.

A useful example is the firmware update released for Naim's earlier-generation streamers in 2021. The update became necessary because TIDAL had introduced a new login and authentication method. Nothing had physically changed or failed inside the players, yet software intervention was required for them to continue using the service.

This demonstrates that manufacturer support is not only about adding new features. Sometimes it is required simply to keep an existing feature operational.

With a responsibly supported product, the manufacturer follows these external changes, updates the firmware and communicates clearly with owners. Once updates stop, however, a player may gradually lose access to internet radio, a particular streaming platform or individual functions within its control app.

The Sonos story: when the app becomes part of the product

The Sonos ecosystem illustrates how closely hardware and software can become connected. On its official compatibility page, the company distinguishes between products that work with the current Sonos app and earlier models that require the S1 Controller. Some products can operate with either platform, while others support only one.

This does not necessarily represent failed product support. Older hardware may not always have enough processing power or memory to run a new platform, while maintaining the S1 app allows previous-generation products to remain in use. The split nevertheless makes one thing clear: the future of a networked audio product depends not only on the condition of its components, but also on the platform surrounding it.

In July 2026, Sonos released a public beta of another new app, aiming to improve the user experience and rebuild confidence after its earlier problematic app transition. Its true success will become clear only through longer-term use. The lesson, however, is already evident: a software update can now influence the reputation of an audio system just as strongly as a new amplifier stage or loudspeaker design once did.

The customer is therefore buying more than a loudspeaker, amplifier or streamer. To some extent, they are also joining a continuously changing service.

Firmware can be both the solution and the risk

Software updates are not inherently a problem. With responsible long-term support, they can be a significant advantage. A firmware update may improve network stability, add support for new formats or streaming services, correct operating faults or even enhance a room-correction system.

The publicly available BluOS release history demonstrates the continuing work required to maintain a network-audio platform. Its updates include changes relating to streaming connections, HDMI compatibility, multiroom operation, security and Dirac Live functionality.

The same ability to update also carries risks. A new version may introduce temporary faults, alter the control experience, remove a previously used function or demand more from the hardware. Owners cannot always choose which version they keep indefinitely, and not every platform offers a straightforward rollback procedure.

Good update practice is therefore not simply a matter of releasing new software frequently. Updates should be predictable and documented, take earlier models into consideration and avoid placing the product's core functions at risk.

Not every smart hi-fi product is destined for a short life

It would be wrong to claim that every networked or active system will inevitably become obsolete quickly. Digital technology does not automatically make a product disposable. Longevity is primarily a matter of design.

It makes a considerable difference whether:

• the product can operate without an internet connection;

• it has conventional analogue or digital inputs;

• it can play music from a local network, NAS drive or USB storage;

• its essential functions remain accessible through physical controls or a remote;

• the network module can be replaced separately;

• the manufacturer states a support period;

• previous firmware and recovery procedures remain available;

• and the product can still be used with an external streamer if its built-in platform eventually becomes obsolete.

An active loudspeaker, for example, may retain its value for much longer if it offers line-level, optical or USB inputs alongside its own streaming platform. The future obsolescence of its network section would not necessarily make its amplifiers and drive units unusable. An external player could give the system another life.

The real risk is not integration itself. It appears when every essential function is accessible through one closed and irreplaceable digital gateway.

What does repairability mean today?

Repairability was traditionally judged mainly through physical considerations. Can the product be dismantled? Are replacement parts available? Is there a circuit diagram? Can the power supply, display, relay or amplifier module be replaced?

These questions remain fundamental, but they are no longer sufficient for a modern networked product. For the unit to be fully repairable, its software layer must also be recoverable.

That may require:

• reinstallable firmware;

• a documented service mode;

• accessible diagnostic information;

• a procedure for pairing or replacing the network module;

• and the ability to start the product even if a manufacturer's server has ceased to exist.

A failed soldered processor or encrypted memory device creates a very different situation from a fault in a conventional analogue stage. The physical component may be replaceable, but that achieves little if the program, configuration or factory authorisation required for operation is unavailable.

Modern serviceability therefore has three layers: mechanical accessibility, electronic repairability and software recoverability. If any one of them is missing, the realistic lifespan of the product may be significantly shortened.

What should we ask before buying?

Sound quality, power, connectivity and compatibility with the rest of the system naturally remain important when choosing a streamer, network amplifier or active loudspeaker. It is also worth asking several questions that rarely appear on a specification sheet.

Does it work without an internet connection?

Not every feature must necessarily remain available, but local playback, physical inputs and volume control should preferably continue to operate without a cloud connection.

Is there another route to the music?

Analogue, coaxial, optical and USB inputs, as well as local network playback, can all provide an escape route if an integrated streaming service disappears.

What happens when the app no longer works with the phone?

Is there a desktop controller, browser interface, conventional remote control or complete set of physical controls? An app is convenient, but it should not be the only door into the product.

What is the manufacturer's support history?

Do not look only at how quickly new features arrive. It may be more important to see whether older models receive fixes, whether update histories remain publicly available and whether compatibility changes are communicated clearly.

Can the fastest-ageing digital section be replaced?

A modular network or HDMI board can significantly extend a product's life. The whole unit should not necessarily need replacing because a communication standard or streaming platform has changed.

Will the core function remain usable?

A network amplifier should remain an amplifier, and an active loudspeaker should remain a loudspeaker, even if some of its intelligent services eventually disappear. This may be the most important long-term consideration of all.

The European Union has also recognised the problem of digital lifespan

The European Union's Ecodesign for Sustainable Products Regulation, adopted in 2024, looks beyond energy consumption alone. Its objectives include durability, repairability, upgradability and the reduction of premature obsolescence. Digital content that forms an integral part of a physical product can also fall within its scope.

This is an important change in perspective, but it does not mean that every streamer will immediately receive a decade-long update guarantee or that replacement parts must be provided for every active loudspeaker. Specific requirements for individual product groups will emerge gradually from the framework.

The direction is nevertheless clear: the lifespan of a product cannot be judged solely by its casework, power supply and physical components. If software is required for operation, continued software support also becomes part of durability.

This is particularly relevant in hi-fi. A quality audio system is not normally purchased for two or three years. Many owners see it as a long-term investment: a repairable musical instrument that may retain its value for decades or even pass from one generation to the next. Digital services should be designed with a similar timescale in mind.

We do not need another war between vintage and modern hi-fi

It would be easy to conclude that old equipment is always better because it has no app, while modern equipment is inevitably destined for obsolescence. Reality is far more nuanced.

A vintage amplifier can also become uneconomical or impossible to repair if a specialised semiconductor, switch, display or mechanical component is no longer available. Older products were not all modular, and suitable documentation does not exist for every model. Age alone does not guarantee repairability.

A modern system, meanwhile, can provide capabilities that would once have seemed impossible: immediate access to vast high-resolution music catalogues, multiroom playback, precise digital volume control, active crossovers, room correction and continuing feature development.

The real question is therefore not analogue or digital, old or new. It is whether the manufacturer has designed the system so that its essential musical functions survive changes in the technological environment around it.

Conclusion – good hi-fi outlives its own app

Convenience is one of modern hi-fi's greatest strengths. A single touch can open an enormous music library, while the system can recognise the room, coordinate multiple loudspeakers and continue playing throughout the home. This freedom should not be dismissed through romantic nostalgia.

Convenience does, however, have a price. The product increasingly depends on external parties: its manufacturer, app developer, streaming provider, operating-system developer and sometimes a remote server.

The hi-fi of the future must therefore do more than sound good. It should be transparently updatable, physically repairable and recoverable at software level. It should retain conventional inputs, independently accessible core functions and connection methods that do not bind it permanently to one app.

A genuinely durable network product is not defined by always offering the newest service. It is defined by remaining able to play music after the service around which it was originally designed has changed beyond recognition.

The best hi-fi does not merely work with the phone we own today.

It outlives it.
