Silent Angel Bonn N16 LPS: An Audiophile Deep Dive

Updated
For years, the idea that an Ethernet switch could influence sound quality was met with justified skepticism. Ethernet is packet based and error corrected, so bits arrive intact regardless of the switch in the path. Yet experienced listeners consistently report differences, and the explanation lies not in the data itself but in the electrical noise that rides alongside it. The Silent Angel Bonn N16 LPS is a purpose built answer to that problem, engineered to deliver clean packets with a quieter noise floor into your streaming chain. Let us take it apart, function by function, and understand exactly why each engineering decision was made.

Brand and Model Context

What is Silent Angel and what does the company focus on?

Silent Angel is a specialist in network audio infrastructure and low noise power, a brand built around the premise that the digital front end of a system deserves the same obsessive engineering as an analog stage. Rather than chasing raw switching capacity the way an enterprise networking vendor would, Silent Angel concentrates on the electrical cleanliness of every port, the stability of timing, and the purity of the power feeding the digital circuits. That focus is what separates an audiophile switch from a commodity office box that happens to move the same packets.

Where does the Bonn N16 LPS sit in the Silent Angel lineup?

The Bonn N16 LPS is the large port count member of the Bonn switch family, distinguished by its sixteen RJ45 ports and its included external linear power supply. Within the Bonn line, smaller models serve listeners who need only a handful of connections, while the N16 addresses systems and homes with many networked devices: multiple streamers, a server, a NAS, renderers in different rooms, and control gear that all benefit from sitting on the same low noise fabric. The LPS designation is significant because it signals that the linear power supply is part of the package rather than an accessory to source separately.

Core Topology and Timing

How does an audiophile network switch actually improve sound?

An audiophile network switch improves sound by reducing the electrical noise and jitter contamination that travel through the Ethernet connection into your streamer, not by changing the audio data. Every switch generates broadband noise from its switching controller, its clock oscillators, and its power regulation. That noise couples onto the Ethernet lines and into the ground reference of downstream equipment. Once inside a streamer or DAC, it can degrade the performance of sensitive clock and analog circuitry, which is where audible effects originate. The Bonn N16 LPS attacks this at every stage: it isolates the ports, it stabilizes timing with a better clock, and it feeds the whole board from a clean linear supply. The goal is to hand your streamer packets that are intact and electrically quiet.

What is the dedicated TCXO master clock and why does it matter?

The dedicated TCXO is a Temperature Compensated Crystal Oscillator that provides a more stable and lower jitter timing reference for the switch than the generic oscillators found in ordinary networking hardware. In a commodity switch, the clock is chosen for cost and to meet the loose timing tolerances that Ethernet permits, since the protocol itself does not need audiophile grade precision to move data reliably. The reason a better clock matters here is subtler. A cleaner, more stable clock produces less phase noise and less jitter driven noise on the switching fabric, and that translates to a quieter electrical output on the ports. The temperature compensation keeps the oscillator frequency steady as the device warms up during operation, so timing behavior does not drift with thermal conditions. The practical benefit is a more consistent, lower noise signal presented to whatever device is plugged in downstream.

Power Supply and Regulation

What does the included linear power supply do that a normal adapter does not?

The included external linear power supply replaces the switching mode adapter that ships with typical network switches, and that substitution removes one of the largest sources of high frequency noise in the entire chain. A switched mode power supply generates power by rapidly chopping voltage at high frequencies, which is efficient but inherently noisy, injecting broadband hash onto both the power rail and the ground. A linear power supply instead uses conventional transformation, rectification, and regulation to produce a smooth DC rail without that high frequency switching residue. Placing the supply in an external enclosure is deliberate too, because it moves the transformer and its associated magnetic field away from the sensitive digital and clock circuitry inside the switch. The audible payoff is a lower and cleaner noise floor, since the circuits are not fighting supply borne noise before they even begin their work.

How does the multi stage linear LDO regulation work?

The multi stage linear LDO regulation cleans and stabilizes the power internally after it arrives from the external supply, using Low Dropout regulators arranged in successive stages to progressively strip residual noise and hold each voltage rail steady. An LDO is a linear regulator prized for its ability to deliver a stable output with excellent noise rejection and minimal ripple. The reason for staging multiple regulators rather than relying on a single one is that each stage attenuates noise further and isolates one circuit block from another, so noise generated or drawn by one section cannot easily contaminate the next. This is the same philosophy used in high quality DAC and clock designs, where local, cascaded regulation keeps the most sensitive circuits, particularly the TCXO, fed by the quietest possible rail. The benefit is that the clock and the switching fabric each see clean, well isolated power, which preserves the low noise performance the rest of the design works to achieve.

What role do the audio grade capacitors play?

The audio grade capacitors provide energy storage and filtering with characteristics selected for low noise and stable performance rather than the minimum cost parts used in ordinary networking gear. Capacitors in the power path do two jobs: they smooth the DC rail by filtering ripple, and they supply instantaneous current when the circuit demands a fast transient. Parts chosen for audio use tend to have favorable impedance and low noise behavior across the relevant frequency range, which helps the regulation stages do their job and keeps the rails quiet under dynamic load. In practice this supports the same overall aim as the rest of the design, keeping the power feeding the digital circuits as clean and steady as possible.

Isolation, Ports, and Build

What are the low noise network transformers and how do they help?

The low noise network transformers are the isolation components on each Ethernet port that magnetically couple the signal while blocking direct electrical connection between the switch and the connected device. Every Ethernet port uses transformer isolation as part of the standard, but the quality of those magnetics varies widely. By specifying low noise transformers, the Bonn N16 LPS improves the barrier that stops common mode noise and ground borne contamination from passing between devices. Because the coupling is magnetic rather than a direct wire connection, noise that would otherwise ride along the ground reference is attenuated at the boundary. The practical result is that a noisy device elsewhere on the network is less able to inject its hash into your streamer through the switch, and the switch itself passes a cleaner signal onward.

What do the sixteen RJ45 ports and gigabit speeds mean for a real system?

The sixteen RJ45 Ethernet ports operating at 10, 100, and 1000 Mbps mean the N16 can serve as the clean central hub for an entire connected audio system with room to spare. Sixteen ports is a generous count, enough to host multiple streamers and renderers, a music server, a NAS, and the network gear that ties everything together, all on the same low noise switch. The 10, 100, 1000 Mbps range covers everything from legacy devices up through full gigabit, which is far more bandwidth than audio streaming requires, so there is ample headroom whether you are pulling high resolution files from local storage or streaming from a service. Consolidating your audio devices onto this one switch also concentrates them behind the same isolation and clean power, rather than scattering them across ordinary switches that reintroduce noise.

How well built is the Bonn N16 LPS?

The Bonn N16 LPS is built as a two piece system, a switch chassis paired with a separate external linear power supply, a construction choice that itself reflects serious engineering intent. Separating the power supply into its own enclosure keeps mains transformer noise and heat away from the delicate clock and network circuitry, which is exactly what you want when the entire objective is a low noise floor. A solid chassis also serves the electrical goals, providing shielding and a stable mechanical platform for the internal boards, the clock, and the port magnetics. The overall build reflects the priorities of the design: isolation, quiet power, and stable timing.

System Integration

Will the Bonn N16 LPS work with my existing streamer and network?

Yes, the Bonn N16 LPS works with any Ethernet connected streamer or server, because it is a standard compliant network switch that requires no special software, drivers, or proprietary protocol. You place it in your signal path like any switch, ideally as the last switch before your streamer so the device receives the benefit of the isolation and clean power directly, with the shortest electrically noisy path behind it. Nothing about your streamer, DAC, server, or router needs to change. The N16 simply becomes the clean hub that your audio devices connect through, delivering intact packets with a lower noise floor than commodity networking hardware provides.

Where should the Bonn N16 LPS go in the network chain?

The Bonn N16 LPS delivers the most benefit positioned immediately upstream of your streaming components, so that the last thing your data passes through before reaching sensitive audio gear is the quietest link in the chain. Because noise reduction is cumulative and the final hop matters most, placing the N16 close to the streamer means the isolation transformers and clean power act right at the point where the streamer would otherwise be most vulnerable. Devices further upstream, such as a router, can remain where they are; their noise is attenuated at the N16 boundary before it can reach your listening system.

Conclusion

The Silent Angel Bonn N16 LPS is a coherent piece of engineering where every choice serves one clear purpose: hand your streaming components intact data with the lowest possible electrical noise. The dedicated TCXO stabilizes timing, the multi stage linear LDO regulation and audio grade capacitors deliver clean and steady power, the included external linear supply removes switching noise at the source, and the low noise network transformers isolate each of the sixteen gigabit ports. As the high port count member of the Bonn family, it is the natural choice for an enthusiast whose system has grown beyond a couple of connections and who wants that entire network sitting on a single, quiet, well engineered foundation.
