Do Power Source and Network Matter to Audio Performance!

1. How the signals affect AV Equipment?

If your are a vintage lover, you must’ve seen the picture below as known as “ Snow Screen “ with the humming sounds.

No matter you saw it on movies or you had it when you were a kid, haven’t you ever wondered why the screen shows that?

This kind of old-fashioned tv receives the satellite signals through antennas above it or on your house rooftop, which it’s easily to be affected by the natural causes, the weather, the RF radiations, the refrigerator, or even a toaster, all the electronic devices have it’s own radiation exposed in the air which can’t be seen by human eyes.

Like heavy traffic jam, when all these signals jammed together, your AV device won’t be too happy, however, as the technology evolving so fast, it’s rare to see the picture like that, clearly presents how the interference affect the equipment.

Back in the old day, your grandpa might just slap the tv surface or fiddle the antennas to make it function again, now this classic scene belongs to the history already, but why if the satellite signals aren’t received, the tv can still present the “ Snow Screen “ , instead of all black.

Well, among all the existing interference, there’re a few can’t be eliminated, and they are the oldest ones, which appeared at the same time as The Big Bang of The Universe. This kind of noise is from the universe, it’s everywhere, and it recorded how the universe was formed, they’re called Cosmic Microwave Background (CMB) , the wavelength is 7.35 mm, we’re fortunate to witness the very first light in the universe, aren’t we? Thanks to the old tv!!!

But, Actually the CMB is only accounted for less than 1% of the whole interference,

As I mentioned from other electronic devices in your home, and the EMI from the earth, the pulsar signal from the universe, the Hawking radiation from the black holes, and so on.

The main factor accounted for over 95% of the interference is embedded in your wall and the device.

The POWER SOURCE. It so directly impacts the AV equipment. Why? Let’s see more!

2. Why Power Source is so important?

If the bloodstream in your body is messy, how would you feel and how would you react? Luckily, you’re able to manage it yourself, to change the diet, to exercise, to have medication and stuff, but for AV equipment, they can’t do such things, hence, we have to help them to have a good quality bloodstream, so that we’ll have the desired performance from them. Plus, music is a real sensitive thing, even the electronic device can sense it!

In order to make the power signal clean, and stable, Silent Angel has developed the Forester Power Module to apply on the linear power supply, unlike general power modules on the market, it adopts fully toroidal-symmetric transformer to feed the high-freq response audio gears sufficiently, owns duo DC outputs (5V/2A).

Now, to prove how Silent Angel’s Forester F1 is better than other general power supply, we made a test, both apply to the same audio network switch, Bonn N8, let’s see how’s the interference difference between them. Tested by Tektronix’s oscilloscope.

The general power adaptor. The peak-to-peak ripple voltage is 114mV

The peak-to-peak ripple voltage is 28.8mV with Forester F1. Almost 4 times less.

Now, how does the ripple voltage wave affect the audio quality?

As a scientific fact, human ears can hear the sound frequency between 20 to 20000 Hz,

So that we used the spectrum analyzer to see the frequency range of the interference range of these 2 power sources.

The general power adaptor. The interference spectrum that exceeds the standard falls within the audible range of human ears.

Given the data comparison, I think it’s obvious to see how a good power source can optimize the audio quality, if you want to upgrade your audio system, power is important!

3. Why Network Switch is an essential part?

After the power source, as we talked about how technology evolving so fast so you might not have a chance to see the “ Snow Screen “ again, it’s that now the network transmission is faster and stronger than ever.

As the power source is the bloodstream, them the network switch is the brain and heart of the AV equipment, in a way, it sort of determines the how the audio sound shapes.

In order to make the network signal clear, and accurate, let it function its main mission well, which is only to transmit the music data without any extra factors or distortions, Silent Angel has developed the specialized TCXO Module to apply on the network switch, Bonn N8, unlike general clock control modules on the market, it adopts 0.1ppm TCXO clock circuit, and high permeability EMI absorber to reduce the noise inside.

Network jitter improvement to heighten data transmitting accuracy, to lower the data distortion.

The general network switch. The jitter is as high as 705ps.

The Bonn N8 network switch. The jitter is lower as 369ps.

And as we kept rambling how power quality is important to the audio quality, it’s the same at network switch, to have the accurate network signal, a stable, solid power source is a no-brainer.

Given the data comparison, I think it’s obvious to see how a good network switch can optimize the audio quality, if you want to upgrade your audio system, network is important!

4. What makes a good audio system?

I know there are lots of articles out there talking about network switch is a nonsense and power source is all the same served by the government, no use to upgrade them, you should be focusing on the DAC, Amp, speakers, and such.

Well, I wouldn’t say it’s all wrong, because it is indeed critical to take care of the DAC, Amp, Speakers, after all, human ears still only can hear the analog signals.

But if you don’t take good care of the front parts of the audio system, which are the source part, the power, the network, the streamer, you won’t have too great audio quality in the end, you’ve got to keep the music source pure, intact, lossless, before it turning into analog signals then to your ears.

Plus you can actually see the interference difference by the testing device, the scientific proofs exist, also all the users’ reviews around the globe exist, what else can we possible do more to convince people that “ Power and Network Matter “ in a audio system.

So what makes a good audio system? There’s no fixed answer, as the music enjoyment is subjective, but one thing I do know is that if you care the audio source enough, them you’d get good feedback from the audio sounds!

If you still highly doubtful, don’t hesitate to contact us to get more information or call out distributors around your location, we’re more than thrilled to let you try out our products to see if they can actually help you get a better music enjoyment.

We’re honored to be a part in your music journey.
