Theoretically speaking, any coaxial digital cable cannot achieve extremely low-loss, high-capacity, extremely high bandwidth, and few electromagnetic interferences. In contrast, coaxial lines are all disadvantages. If the coaxial line is as good as some magazines, why not use coaxial fiber instead of coaxial cable for long distance information transmission? Moreover, there is a reflection impedance on the coaxial line, and the phase distortion cannot be ignored. The optical fiber does not have these weaknesses at all. No matter from theory to reality, optical fiber is the best digital line. It is not surprising that some foreign audio magazines have this strange theory. One is limited by the conditions of its equipment and the technical level and experience of its contributors. Two fiber optic cables are cheaper and the coaxial line is more expensive. It is self-evident which distribution lines are profitable. It is also highly recommended for coaxial lines for commercial interests.
I use the turntable for Philips CDM12.0/12.1/ 12.4/12.6 and professional turntable CDM36, Pioneer CLD-303 LD machine turntable, coaxial cable and digital fiber money for sound quality comparison, connect Coles HDCD DAC decoder, get the following results .
l. Philips CDM12.0/12.1 turntable, optical fiber cable can hear the feeling of 'hard' and 'gone floating', CDM12.4 has improved (improved), while CDM12.6 only slightly sounded and hard feeling .
2. Pioneer LI's rotary sound is heavy, and the sound is hard and floating is very obvious.
3. The Philips CDM36 turntable has absolutely no "hard" or "gone" phenomenon. The performance of the optical fiber cable is repeatedly and quickly switched at the input of the decoder compared to the coaxial cable (expensive price to 650 US dollars per meter). Can't hear the difference. If there is a slight difference, only the optical fiber will perform better and the sound will be cleaner and thicker. Don't forget that the optical fiber used is just 100 yuan/bargain.
From the above experiments, it can be seen that the optical fiber line is the most neutral, the least loss, the highest resolution of the digital line, or how can you hear the "hard" and "gone" of the sound caused by the loss of information on the low-grade dial and the coaxial line can not hear This difference comes. This shows that the coaxial cable has poorer resolution than the fiber optic cable and cannot distinguish this slight difference. The resolution of the fiber optic cable is so high that “they don’t rub the sand”! This also tells us that if your equipment is not high enough, especially if the quality of the gold is low, please do not choose the fiber optic cable. If we spend thousands of dollars to buy a coaxial cable, we might as well use this money to purchase Philips CDM36 turntables, and only use inexpensive fiber optic cables as digital cables, so the quality of your equipment will be greatly improved. You can try it out.
