| CD vs 24bit/96kHz Hi-Res | 29% | 41% |
5. Opinions of Industry Experts
Wang Ming, a famous audio engineer, mentioned in a recent interview: "Although the CD specification has a history of 40 years, its 44.1kHz/16bit design can still cover most of the audio information perceptible to the human ear. For most consumers, CD sound quality is completely sufficient. What is important is the recording quality of the sound source itself."
6. Purchase suggestions
1.Getting Started: Recommend entry-level models such as Sony CDP-CX300 (about 1,500 yuan)
2.Advanced options: Marantz CD6007 (about 5,000 yuan) equipped with HDAM amplifier circuit
3.Collection suggestions: Give priority to SHM-CD, Blu-spec CD and other special material versions
Conclusion
In today's pursuit of high-resolution audio, CD still occupies an important position with its stable performance and mature ecosystem. For music fans who pursue sound quality but don't want to make any sacrifices, CDs are still a cost-effective choice.
