Digital signals, namely 0 and 1, until today, many people still think that since it is a signal of 0 and 1, there should be no difference in quality of the transmission line itself. Physically, there is natural distortion in transmission, no matter whether it is an analog signal or a digital signal, the distortion comes from many aspects. There are different forms of radio frequency interference such as EMI and RFI from the outside world, the mutual interference between internal conductors, and the quality of the conductors. Affects, connector quality performance, will cause distortion. There is no distortion-free transmission line on earth. The competition between brands and series is more and less distortion. The less distortion, the better the quality and the higher the enjoyment. For HDMI cables, there are also electricity problems. HDMI must have conductors that only transmit electricity. There are many impurities in the mains, and the shielding design is not good enough, which will naturally affect the performance of images and sounds.
Janet's comments:
<<Inakustik Samsung STAR>>
。Hi Fi audio uses inakustik fever cable, which is composed of two-channel signal cable, speaker cable, LAN cable and HDMI cable. The frequency is very high
。As far as the entry line is concerned, the three-dimensional image of Star is of a high standard, and the layers are not sticky.
。I think it is enough for TV image replay, for game images, and sound and picture quality in terms of price.
。In terms of sound, the full frequency has a good sense of balance, the clarity of details is sufficient, the vocals are powerful, and the explosive force is quite strong in HDMI cables under 500 HK dollars, which rarely makes me feel the air.
<<Inakustik Four Star PREMIUM>>
。Premium is a four-star HDMI cable second only to Excellence, and the price is a lot cheaper than Excellence
。Signal transmission adopts 28AWG twisted conductor, three-layer shielding and 24K gold-plated connector
。"Lucy" features the right proportions of the facial contour in the close-up, the hair and eyebrows are slender and natural, and the sense of three-dimensionality and depth can be said to be the best in this test.
。The human voice is sweet and beautiful, the high frequency is slender, the overall sound pressure is relatively low, and the clarity of the sound is so that you can hear it carefully.
