Our LG AUDIO Luge series Permalloy audio transformers and assembled active preamplifiers, passive preamplifiers, signal converters, selectors, and volume controllers have been recognized and praised by many users.
At present, the market is chaotic, and fisheyes are mixed. The so-called imported 6N single crystal copper enameled wire is advertised on the market, and the imported 6N single crystal copper enameled wire is faked with domestic ordinary enameled wire. It is really a three-no product without a brand, no qualification, and no certificate.
Our shop uses genuine Shanghai Jiquan series 5N single crystal copper enameled wire winding transformers, the effect has been improved significantly, and the sound quality has a greater improvement and progress, which is different from fake products.
The Permalloy series audio isolation transformer wound with Jiquan series 5N OCC single crystal copper enameled wire, as long as your playback equipment is good enough, know how to listen, you can clearly hear the difference, especially with AB fast switching comparison , Immediately heard the difference.
OCC single crystal copper wire is used in the production of audio wire, which is a major breakthrough in the audio wire manufacturing industry in recent years. Scientific experiments have proved that single crystal copper is a kind of high-purity oxygen-free copper. The entire copper rod is composed of only one grain, and there is no "grain boundary" between grains. The "grain boundary" will reflect and refract the passing signal, causing signal distortion and attenuation, and thus has very high signal transmission performance.
5N OCC single crystal copper enameled wire is obviously different from general enameled copper wire. It is not comparable to general OFC copper and low purity copper enameled wire. Especially for audio, it has a positive impact on sound quality. 5N OCC single crystal copper enameled wire is used for audio signal cattle, vinyl MC phono boost cattle, amplifier input and output cattle, passive boost cattle, audio signal cables, etc., all have excellent performance.
The casting is subjected to special heat treatment, so that single-crystalline conductors can be obtained, and each crystal can extend more than one hundred meters. Therefore, there is only one crystal grain in the length of practical application, so there is no so-called "grain interface". When the signal is transmitted, there is no need to pass through the "grain boundary" between the grains. Because the signal is easier to penetrate and conduct, the loss is extremely low, which is called a perfect CP copper wire.
5N OCC features: multiple times increase the purity of unidirectional crystal or high purity single crystal composition, less segregation and low impurities. The average crystal length is 125m, which is more than 50-100 times that of general oxygen-free copper (OFC); the cost is also more than 8-15 times that of oxygen-free copper (OFC). Since the crystalline cross section of 5N OCC wire is theoretically zero, the signal can be kept intact and lossless during the transmission process.
The order of metal conductivity from strong to weak is: silver, copper, gold, aluminum. The top conductive metals are the conductivity coefficient; silver — 0.016, copper — 0.0172, gold — 0.023, aluminum — 0.028. Silver and copper are both excellent electrical conductors. The electrical conductivity is only 0.0012 small, and the difference in resistivity is very small.
A merchant once said that his single crystal copper enameled wire is 8% to 13% smaller than the ordinary copper enameled wire. It is unscientific that the calculated electrical resistivity of copper is less than that of silver, which violates the laws of physical nature. The department also consulted experts on the metal materials of single crystal copper manufacturers, and also compared various domestic and imported single crystal copper enameled wires / single crystal copper silver-plated enameled wires and ordinary enameled wires, and found that there is almost no difference in copper resistance. The three-and-a-half-digit digital multimeter barely measures the difference. Therefore, it is unscientific that the resistance of single-crystal copper enameled wire is 8% to 13% lower than that of ordinary copper enameled wire, which is purely misleading and self-deceiving.
