Quantum Burning Technology V 5.1

Home 5 Power 5 Quantum Burning Technology V 5.1

In summer 2008

The core of the machine consists of a crystal oscillator feeding a 70-watt amplifier module, the module drives a load before entering the in-house developed control system.

From the logic of the control system, current required for each cable will be adjusted on the fly. Thus, avoiding the problem of over-running or under-running the cables.

Before this final version, the prototype module came into being in summer 2008. As experimental materials were used for the trial circuit design, the bandwidth was just 30 Hz – 16 KHz.



We then improved upon the original design in the second phase. We upgraded the parts and materials, and did some schematic modifications to push the bandwidth to 20 Hz – 22 KHz.

We then started to focus on the power supply section to enhance the results of running in cables.

During the second phase of improvements, we did not only improve on the bandwidth, but also put extra attention to the power supply as well. At the power supply section, we added eight pieces of JENSEN 1 mF copper foil capacitors, one each of 0.1 mF, 0.01 mF and 0.0015 mF silver foil capacitors in order to compensate on electrical phase issue.

Enjoy music

After the second phase upgrade, we further confirmed the positive effects of minor tweaking on the power supply section had on the run-in results.

We discovered that with the same type of cables, when run in with the additional capacitors, the result turned out to be quite interesting.

When run in without the additional capacitors, the frequency extensions appear to be similar. However, with the additional capacitors added, the minute details and overtones carry the same warm tone of the JENSEN capacitors.

All the while, we feel that every cable we manufacture should go through a complete frequency sweep of run-in. We feel strongly that our customers should not endure the difficult time of running in the cables, they should be able to start enjoying music the moment they get our cables.



Our second generation machine, the JENSEN capacitors tuned edition, was in operation from October 2009 to December 2011. For two years, the process of running in cables has never failed to be part of our Standard or Procedure for every piece of cables we make.

Whenever we do home visits for setup and comparison, we have never failed to realize the usefulness of this fundamental belief.

Hence, we have always been talking to our engineers in hope of making a new model that could match the bandwidth of SACD frequency extensions.

Let us try to explain our technology in a more illustrious manner.

The process is analogous to loading software for computer. By running in the cables using different frequencies, we are able to maximize the frequency response, improve the performance and minimize the shortcomings of the cables.

Quantum Burning Technology

In the latest design , with materials of even higher quality, we were able to further stretch the bandwidth of the machine.

We increased the size of the transformer in order to increase the stability of the electrical current.


In addition to that, we have also added a brand new power cleansing technology into it.And this technology, Quantum Burning Technology, is also how the new cable run-in machine got its name.

We then finalized the specifications at 70 watt of amplification. The amplification module has a dynamic range of 24 volt, a frequency response of 0 Hz to 50 KHz and topped up with the new power cleansing technology.

Let us explain to you the new technology. The technology is based on the principle of power synchronous resonance.


By applying a similar but reverse polarity frequency against noise, the noise will be cancelled out. This technology works analogically similar to the principle of noise cancelling earphones.

Our QBT module produces eight discrete frequencies, namely 120 Hz, 60 Hz, 30 Hz, 15 Hz, 7.5 Hz, 3.75 Hz, 1.875 Hz and 0.9375 Hz.

Resistors and inductors are used as load. There is also benefit using inductors as load. A 200 mg of magnetic field will be generated, thus, acting as a shield to the circuit. By using the QBT module, it does not only cancel out noise, but also repel external electromagnetic interference.

Drilling deeper

We will explore further into the specifications for the different channels.

There are five channels in our QBT Cable Run-in Machine, they are for speaker cables, power cords, digital cables, RCA cables and XLR balanced cables.

The first two channels, for speaker cables and power cords, the run-in signal is rated at 70 watt, 24 volt and a frequency response of 0 Hz to 50 KHz.

The latter three channels, for digital cables, RCA cables and XLR cables, use only a mere 5 watt as the cables are far smaller in diameter. However, the signal remains at 24 volt and the bandwidth remains at 0 Hz to 50 KHz respectively.

From our previous experience, if overly high current is used to run in interconnects, over run-in could happen and bring adverse effects to the sound.about how much higher the run-in signal is as compared to that of normal listening session.

The signal between the source and preamplifier, depending on source type, carries a voltage of 2 volt to 3 volt. If the input impedance is about 10 KW (some as high as 1 MW), then the load power is calculated at less than 1 mW. We use 5 watt for our run-in signal, which is 5000 times more than the source signal. Added by a full frequency sweep every 1.7 seconds, the cable is undergoing way higher utilization rate than when used to listen to music at moderate volume.

For signal between the preamplifier and power amplifier, it could reach as high as 10 volt. If the input impedance of the power amplifier is 4.7 KW, the power calculated would be at about 20 mW. In that case, QBT is 250 times stronger than normal signal strength.

When listening to music normally, the signal would be varying at tens to hundreds of millivolt. Hence, the actual power ratings are essentially so much lesser than1 mW and 20 mW respectively .

Voltage is normally within 110 volt to 117 volt for power cords. Even though the electricity is fixed at 60 Hz, we are using 0 Hz to 50 KHz to run in the power cords.

As for speaker cables, on average, we seldom go beyond 10 watt when listening at moderate volume. Big current flow only happens when there is a huge dynamic swing, but we are sure people would not keep on listening at such high volume. Furthermore, most music would not even fully cover the frequency spectrum. But we still use 70 watt of continuous full frequency sweep to run in the speaker cables, making the signal strength tens of times higher than.
