Ask for this Sony CD walkman information

I am also an audiophile. Basically, I collected tape drives. D350 is really a classic old machine. I found some on the Internet for reference.

(Reprinted) Playing with computers these days, many good machines are hovering in their hands, so it is difficult to get together and compare them. Although I know that in the old walkman, the so-called timbre is mostly subjective, mainly depending on your own preferences, but since there is such an opportunity, it is natural to "show off" and draw cakes for friends who don't have it. I hope you like it. ?

Let's invite today's protagonist:-Sony? D303/350?

These two machines are Sony's classic old machines, each with its own unique charm, and the appearance is as shown in the figure, so I won't go into details.

First, the shape of the article:?

303/350 is similar in appearance and square in traditional appearance. I like it very much. The materials used for appearance are all very good. As for what alloy it is, I don't know, but the feel, luster and strength are much better than those of the current machines. The projected area of 303 is slightly smaller, and the thickness of 350 is slightly less, so I estimate that the two machines are similar in size and weight, and both are heavier, but?

Their panel design is far from each other except the general outline, material and volume, and there are two typical styles and design intentions; The 303 panel is relatively simple, and there is a convex parabolic arch in the middle of the machine, which can be seen clearly in the above picture. Combined with the square design, there is a sense of combining rigidity with flexibility. The simplest basic function key is designed and placed in the middle and lower part, which strengthens the visual center of gravity, has a sense of security and highlights the beauty of simplicity. ?

The design of 350 is completely the opposite route, with rigid lines and many function buttons, which are densely covered with the whole panel. The LCD panel is also bigger and more powerful than the 303. It has all the functions of the platform, including the free music selection function of 1- 10+, and the complete industrial design style is also very powerful.

Second, the sound article?

A great deal of space has been devoted to introducing the main appearance features. Let's talk about the sound:) Because I got the 303 this morning, there was something wrong with the power supply. After listening to a few songs with batteries, the evaluation was inevitably one-sided. I hope my friends will criticize and correct me and discuss it together. ?

Recording for listening and testing:?

First/fifth: unplugged sky (D9 with earplugs for Aihua)?

Above 303: Full timbre, powerful low frequency and magnetic voice. It's really a nice machine, but I feel that the speed of tambourine is slower than that of 350 or above. It seems that the problem of low frequency speed of old machines is more common. Compared with 350, which I have heard very well, his voice is much richer, well decorated and has less burrs in high frequency. The sound is more emotional, soft, warm and low-frequency. However, in the sound stage, in subjective hearing, 350 is more open and natural, more atmospheric, tough but more bony, clear and clear, 303 is more flexible and slightly vague, and it has a unique flavor. ?

The eighth song: reservation. (Aiwa D9 with earplugs)?

The first 40 seconds of this song is Wang Jingwen's female voice, which is very elegant and clear. There are obvious traces of intermediate frequency decoration on 303, but the temperature is good, charming and euphemistic. Proper modification and strengthening highlight the confusion of women in love? And persistence, I am very touched. The voice on 350 is slightly dry, but it is more natural, and there is no such strong emotional catharsis. However, the sense of space and air sound are excellent, which plays a role in rendering from another angle, giving people a sense of loneliness in love and making people feel sad. In the later orchestration chords, the advantage of 350 is more obvious, and the sense of music is much stronger than that of 303. ?

Generally speaking, 303 is soft and firm, and its timbre has its own characteristics. In theory, 303 is better than 350. After all, the high frequency of 350 is still slightly rough, but from the sound field and function, I personally prefer 350. What I feel here is my own recognition. Please don't think I gave them the order. I don't think I have the strength to do such a job, and I always believe that what I like is the best. ?

Speaking of this, by the way, after listening to Chopin's two piano pieces, the sense of space of 350 is really more real, and the output of 303 is bigger than I expected; Personally, I think the sound of 350 is between the sound quality of 303 and the sound field of 250, which is a good choice ~

Third, summary:

In terms of sound effects, DBB is obviously better than MB. Although the low frequency sense of 350 MB has improved a lot, the noise has also been amplified a lot, and the sound field compression has also become very severe. The DBB of 303 is not as good as that of 350, but it is relatively balanced. The effect of opening a DBB with a slightly modified D9 is still excellent, and the sound effect is also a strength of 303. In order to strengthen the atmosphere of the first grade +DBB, it is more cost-effective to sacrifice a sound field to listen to some songs. In contrast, 350 really doesn't work, and you can't listen to it when it's on. The sound effect is useless, so it's better to do the same as 250, without any sound effect at all, and it's also very personalized.
