Magic fuses!

Quantum Sciences has been working on research and development of their fuses for over 22 years. Their proprietary technology removes what they call "bottle neck distortion" making the sound reproduced by your components more alive, unbelievably dynamic with an ultra dark sonic background. Enjoy the musical experience from your home like never before.

The fuse is one of the biggest bottlenecks in any audio component performance. Their belief is that the biggest bottleneck in an audio components' performance is the fuse. All of the power feeding your component (probably from a very expensive power cord) ultimately runs through this tiny filament of wire, an ten cent part, before it enters your system. Power cords can and do help, as does power conditioning, but ultimately it is the fuse that is the weak link in the power chain. QSA has spent 22 years working to eliminate this bottleneck. Their line of fuses spans a wide range of performance levels and price points. All are designed to eliminate the distortions created by a typical fuse. The end result are fuses that allow your components to perform their best. Drawing you into the music on an emotional level you might not have thought possible. QSA's value proposition and challenge to the customer it that these fuses will outperform the sonic benefits power cords, and cables costing many times more.

Our listening tests of the Red Fuse (1200 Euro) convinced in seconds of their value. It is no understatement to say that they are a paradigm shift in our concept of what matters in the audio system. These tiny devices bring out the emotional/musical potential of any component like no other tweaks or accessory we have EVER listened to has. The amount of performance that these fuses allow your component to perform at is well worth the asking price. We guarantee it.

Bottom Line: These fuses offer the most significant upgrade in sound quality compared to any other accessory, cable, or tweak we have ever tried. It's not even close, they redefine value for high end audio. We encourage you to try them and we stand behind them with our 30-Day money back guarantee.

QSA Fuses in particular are directional! Electricity should flow in the direction of the arrow. Direction of the primary fuse can only be determined using a voltage detecting screwdriver. Remove the primary fuse, re-insert the plug into the wall outlet, switch on the device and determine on which of the two contacts of the fuse holder the lamp in the screwdriver lights. This is the hot side of your fuse holder, the tail end of the arrow should point toward this side. In all other cases you should listen to the fuse inserted in both directions. One direction will sound more detailed with a more natural timbre. This is the correct way.

Many audiophiles ask us about the soundwise differences between the Yellow Fuse and the Synergistic Research Orange Fuse. Dutch tweak expert and reviewer John van Polen compared them: "The SR Orange en QSA Yellow fuses contribute distinctly different to the sound. The SR Orange is all about a homogeneous, rather easy-going sound with nicely saturated tone colours. The QSA Yellow fuses on the other hand yield breathtaking dynamics, a silent background and a very clear and clean sound. Bass is extremely fast and deep. On the flipside, the QSA Yellow does not provide the richness in the midrange the SR Orange does. So there is no "better fuse"; it all boils down to taste, system and musical preference. Perhaps one could say the QSA Yellow is most suitable for the audiophile looking for excitement while the SR Orange serves the music lover who appreciates pure rendering of classical music best."

(Thought some might find interest in this, it is translated but reads pretty good...)

The current limiting function of the fuse is the basic common sense of the protection equipment, I believe everyone knows, needless to say. I have known the importance of the fuse from the beginning of the road to audio. It is not only its role in protecting the safe operation of the equipment circuit, but also the only way for it to dominate the current-starting equipment. This bottleneck often kills the audiophile power supply. The cable plays the best sound effect, so in the audiophile audio market, the fuse is already an important part of audio accessories. There are many fuse products on the market, the price gap is huge, and the sound is biased. Finding a fever-grade fuse is always inseparable from the few well-known brands. As long as a product has market value, it will attract competitors to share a piece of the pie. This is an era of weeding out the weak and staying strong. It is necessary to show housekeeping skills and have advanced processing technology as the backing to gain a foothold.

Generally, enthusiast-grade fuses start with conductors and do not hesitate to use gold, silver, copper, etc. to make alloys, or even pure silver, which is much better than using low melting point lead-tin alloys, zinc, copper, and copper-plated silver materials. Some of the copper caps at both ends are nickel-plated, polished and then plated with a layer of rhodium platinum, palladium or platinum, and even worse, a layer of pure copper is plated on the tellurium copper, then a thicker layer of silver, and finally a layer Pure gold, combined with the sound characteristics of gold, silver and copper, in addition to improving the electrical conductivity, it is also helpful for sound calibration. Traditional fuse tubes use quartz glass tubes, as well as ceramic tubes. Some contain ore powder and absorb resonance in the fuse tube, which can reduce the harmonic distortion present in the input current and ensure better power supply stability. In order to improve conductivity and sound transparency, silver-tin soldering is used, and a more advanced special crimping module is used without soldering at all. Finally, some fuses also reduce internal resistance through freezing treatment or high-voltage pulses, and conduct faster.

As mentioned above, some of them are unique production and processing technologies of a certain brand, but they are also inseparable from the fields of conductor materials, electroplating technology, welding technology, etc. The following introduces Quantum Science Audio's fuse products, which are truly breakthrough production and processing technologies. The sound is vivid. I have known Quantum Science Audio’s technology as early as three years ago. The metal activation technology that it promoted was initially only applied to metal conductor wires, and then gradually expanded to vacuum tubes, adaptors, capacitors, electronic parts, etc., as well as equipment. The metal case is really incredible. I have to mention the Quantum Science Audio R&D team. Under the leadership of Leader International, Mr. Zeng has overcome many difficulties. Mr. Zeng has been in the audio industry for more than 30 years. Every issue of Chinese and foreign audio magazines is always uninterrupted, with unremitting spirit to face and solve, with strong comprehension, can draw inferences from one another, and many audio mysteries can penetrate the mystery.

Mr. Zeng has been in the audio industry for more than 30 years. Every issue of Chinese and foreign audio magazines is always uninterrupted, with unremitting spirit to face and solve, with strong comprehension, can draw inferences from one another, and many audio mysteries can penetrate the mystery.

Closer to home, back to the Quantum Science Audio Quantum Science Fuse test. The models are divided into five grades by color. From high to low, they are red, light purple, yellow, light blue and black, and there are four under each model. Series, respectively, A-Analog for analog equipment; D-Digital for digital equipment; S-Sub-woofer for active subwoofer; V-Video for video equipment. The four series are tuned to make the equipment unique effect. Fuse values ​​are available, ranging from 50mA to 30A. Both long (30mm) and short (20mm) are available. Both fast and slow burn are available. British (25mm) have 4 values ​​of 3A/5A/10A/13A. , All QS fuses have a variety of safety certifications CCC, UL, VDE, in order to comply with the regulations of different countries.

Looking at the content of the advertising leaflet, the ten thousand yuan-level top class Quantum Science QS Fuse has ten American core technologies. After chewing the text, I feel that some of them are illusory and vague. I understand that it may involve trade secrets. It is impossible to say too much to prevent plagiarism. One point: The music release/burst technology can reduce the impact of digital sound. Mr. Zeng has repeatedly emphasized this core technology and this is the only one. Another key point is the metal activation technology: increase the amount of electrons flowing in molecules per second, and the larger the increase, the better the effect, which can increase the dynamic range and sound density. Metal molecular compression arrangement technology: Due to the reduction of internal resistance, the speed of transient response is accelerated, and the impedance is 5 to 30% lower than other brands. Metal molecular noise drop technology: Make the background more quiet and the details clearer. Resonance point adjustment technology: lower the resonance point of the fuse tube to reduce the vibration of the conductor molecules in the tube, so the sound field is more stable and the image is clearer. A small black sticker on the tube body is used to adjust the physical resonance point. Using special elements and quantum technology, the elements are put on the surface to reduce electromagnetic interference. Add a small amount of 10.5% conductive ultra-high pure silver tin wire to improve sound transparency. The metal caps at both ends of the fuse are coated with micro-nano oil to make the contact points closer. As the contact points increase, the amount of current passing through them also increases, making the low frequency more stable and diving. The fuse conductor adopts superalloy to adjust the sound, the sound has an excellent balance, and there is no loss of low-frequency volume at low level.

Since the replacement of the new generation Esoteric K-01Xs SACD player, the fuse is directly welded on the circuit board, so the test fuse falls on the front stage, the rear stage and the split power supply. The current fuse has been continuously updated for several years, and the sound effect has been quite satisfactory. First, replace the QS "red" Analog fuse for the previous Artemis Labs LX-1, and listen to Zhao Peng's "Subwoofer 3 Car" XRCD2. The voice is high and the mouth is focused. Sharp and transparent, full of air,

The knot of the instrument is exquisite and embossed, the high-frequency extension is more extended, the details of the weak tone are clearer, the sound quality density is higher, the music atmosphere is more lively, the low-frequency harmonics are more abundant, sitting on the sofa also feels low-frequency diving. Then I replaced the Artemis Labs SP-1 300B XLS with 2 fuses on the rear stage, the same "red" Analog, and then listened to Zhao Peng, the sound has been blasted out, the vocal texture is rich, the image is more three-dimensional, the music flavor is strong, and the sound quality It is more consistent, and the transient speed and micro dynamics are comprehensively improved. It is as transparent as a microscope and reproduces in detail and clear. The position of this post-level fuse has been replaced by the fuse tested over the years, but it has never performed the full sound effect this time. , The sound quality and sound effects have been upgraded several levels in succession, tut tut amazed!

Finally, replace the QS "red" Analog on the power supply of the rear stage. The noise on the platform is lower, the image of the instrument is stable as a rock, the positioning is clear, the low frequency is more bounce, the lower potential is more calm, and the sound field is more spacious. Taller and wider. In the end, I used the live recording of "Impression Lijiang" gold disc for the ultimate test. This 2006 recording directed by Zhang Yimou was recently relaunched on the gold disc version. The sound effect is better than the CDR in my hand. There is no suspense. Listening to "Friends Come" It's-Drinking", the crowd's shouts are sonorous and powerful, the front and back positions are clearly explained, the sense of hierarchy is clear, and the sense of space on site is vivid.

In the following "The Voice of Su Gu Tuk", the strings of the stringed instruments at the beginning were tense, and the calls of the crowd flew out of the left and right speakers, reflecting the large performance venue. The density and transparency are very high. The most powerful low frequency is stronger than that. In the past, there was a shocking feeling. I am afraid that the bass beats are distorted. Now the transient speed and control are improved. The sound quality is calm and oppressive. no. From the above test of Quantum Science's top Analog fuse, the sound quality and sound effect of the pre-stage and post-stage have been fully upgraded to the highest level. Seeing that Pu Dong’s last test was also QS’s top-level Sub-woofer fuse. He used to use Procella P18 18-inch subwoofer + M&K MX350 SFXL 12-inch subwoofer to create a horrible sense of pressure. Now M&K 12-inch + QS Sub-woofer The fuse can achieve the same effect, and different series of fuses do have unique effects on the equipment.

Quantum Science Audio uses innovative and breakthrough technology to produce fuse products. Metal activation technology is also becoming more mature. It can be applied to various audio products. Regardless of the price, QS's top fuse is indeed the most comprehensive and effective product I have tested. , But the price is also the most expensive on the market. Fortunately, he has four other models. The retail price of the most basic model is only more than two hundred, which is rich and frugal. Lastly, QS fuse is directional, and there is an arrow on the fuse tube. It must be installed along the direction. If it is not correct, the treble will appear dim and lack vitality. You may wish to remove it and install it in the opposite direction before listening. Once again, there must be a difference.

Quantum Science Audio Black. Review by Peter de Kok
Quantum Science Audio Black.
Ik heb deze zekering in mijn versterker nu een week in gebruik en het is voor mij muzikaal de beste tweak die ik in de afgelopen 40 jaar heb toegepast daarbij is het eenvoudig en goedkoop.
Ik ga mijn bevindingen niet omschrijven in een wollig verhaal ik kan hem van harte aanbevelen zeker voor die prijs van 24 euro. (Geplaatst op 27-11-2021)
