Now, the performance of the integrated sound card on the computer has been greatly improved compared with before, which can basically rival the entry-level independent sound card. You can still distinguish between lossy and lossless. If you don't have a better playback device at hand, you can use a computer instead. Computers should not be too old, preferably desktops. Motherboards should be big brands such as Gigabyte, Asus and MSI. Don't use cool me, QQ music, thousands of listening software on the computer, which is unprofessional. The most commonly used professional player for listening to music on the computer should be foobar.
Then I want to talk about the sound source. The recording quality of general pop music itself is not high, and the most important thing is that post-mixing will cause great loss of sound quality. So you'd better choose some classic listening discs to listen to. The resources of these audition discs can be found in the forum. But at present, these audition discs are flooding, and many of them are gimmicks used to make money. So don't download it when the title says "XXX audition" or "XXX burn CD". Generally speaking, you can choose the audition discs made by famous record companies, such as Tayrac, Tiger Fish, Hugo and Bai Fei. And you can also choose the audition discs of well-known headphone audio equipment manufacturers such as Iron Triangle, Boya, Senhai and Tianlong.
In addition to these special audition discs, there are many ordinary albums with high recording quality, and such resources should be said to be the most abundant. You can choose according to your own taste. But when choosing, don't judge by the download volume. It's best to search online for the evaluation of the album. Generally, high-quality discs will have expensive and professional evaluations.
