What is the sound quality of PCM-50? Used friends talk about it.

Quoted from a well-known moderator's post, after all, answering this question requires experience and equipment, but also comparison!

Let me briefly comment on some personal equipment around me, mainly D50, and compare it with UFO suit, Sony R50 and IPOD CLASSIC.

& lt 1 & gt； D50. Generally speaking, the atmosphere is grand, the frequency response is wide, the resolution is high, and local monitoring is performed. The positioning is very accurate, which is not comparable to ordinary people. The sound began to be a little stereoscopic, not flat. Because of the high resolution, good separation and distinct music levels, when playing classical music, various musical instruments are patchwork, and wave after wave of musical instrument frenzy makes people feel the charm of big weaving classicality. The most valuable thing of D50 is the high-quality reproduction of the original sound source, that is, the so-called real playback. 25WM thrust (this is the real thrust, unlike those MP3 players who bid with bonzi, only 5MW dares to bid 30WM falsely, which will fool the dead into not paying for their lives), and the volume is already very high when it reaches 1, and even the ears can't stand it. High frequency, good ductility, bright and smooth, but not gorgeous. Maybe I pushed the EX700 too hard, and it was a little harsh when listening to nightwish soprano. But the performance of musical instruments can be described as perfection, especially violin, piano and other musical instruments. Virva's mandolin concerto came down, and the crisp and melodious sound rolled down, which really made people feel at a loss. The sound of mandolin is like dew, sometimes dripping down and sometimes volatilizing in the sun. I can still feel the strings. It's really amazing. Intermediate frequency, the deepest feeling is that the density is really large, and it is easy to get tired after listening for a long time. The sound is almost real, and there is almost no sound dyeing. Personally feel thin and cold. To tell the truth, listening to female voices is quite tragic, especially lyrical female voices, such as Faye Wong and Zhou Hui, which are really straightforward and boring. Or, it's too hard, but it has a good sense of lines. Boys are not bad. For example, wei li's "Forget the Year" is very good and sings with great feelings. He could hear Li Wei breathing and swallowing. Among them, he could hear that the singer was still very emotional, and his throat seemed a little choked, as if he was going to suffer. The melancholy mood came out at once. Good, good, he was moved. After listening to Xueyou's love, it is the same. It seems to be suitable for boys with deep voices. Low frequency: Very distinctive. To tell the truth, the dive is deep, the elasticity is just right, and the speed is moderate. The sense of quantity is just right. To tell the truth, the low frequency below D50 is the best I have ever heard. At the California Hotel, when the drums come, you can almost feel the vibration of the drums. This is the so-called air sense (exaggeration). Then positioning, considerable preparation, drums, guitar sound, the applause of the audience below is fragmentary, you can imagine their position by closing your eyes, and you can hear the cough of the audience halfway, which is very powerful. Finally, talk about the sound field. To tell the truth, this is the weakness of D50. The sound field is actually not big, at least I'm sorry about its size. The transverse sound field is not bad, but the depth is not enough. So the voices sound quite close, and of course some people like them. It is not good to be too far away. For example, like Sony's flagship XK, the voice is far away, and the sound field was very satisfactory at first. Very good. Listen again, why is this sound field so empty, or so fake, as if it had been artificially enlarged? It's a tragedy, XK. Even more tragic is its role. The most important flagship of Sony Walkman is not as good as its own recording pen. It's time to reflect, Sony. ZJB Zen still makes me feel much better in this respect. Well, that's about it. It is estimated that D50 can only push earplugs like this, and the control is still a bit excessive. I guess LO will be much better. When you hear it, put it in your ear and make a good comment.

& lt2 & gtBeosound 2。 So far, this is my most satisfactory. Flying saucer +A8, what a beautiful voice, radiant and exquisite. You have to believe that MP3 can produce such a good sound, the format theory is not absolute, and sometimes tuning is also very important, so I still have to admire others B&; Oh, Andhadhun. Generally speaking, the sound of flying saucers is bright and warm, and the atmosphere is as warm and pleasant as autumn sunshine. High frequency: The high frequency of flying saucer is distinctive, sharp and bright, but it is well controlled and never harsh. The extension is good, which is more than enough for the interpretation of ordinary violins. Generally speaking, it is gorgeous and smooth, especially in the middle and high frequency parts. Coupled with the high-pitched voice, listening to popular female voices in Europe and America, such as Maria Kelly, is almost perfect. Intermediate frequency: It is warm on the whole, with a certain thickness, moderate vocal density, less exaggerated than D50, and not tired after listening for a long time. Low frequency, good quality and quantity, good elasticity, freely retractable. Tri-band connection is smooth with almost no defects. The performance of popular music, especially the "passion point" popular in Europe and America, is more perfect. At the same time, it is very imposing, with good sound positioning and layering, especially the sound field. The A8 nearly oval music hall is the best sound stage equipment I have ever heard. The analysis is acceptable, and the performance of classical music is also good. But the sound has a certain "graininess", and the sense of lines is not as good as D50. At the same time, the medium and high frequencies are sometimes too sharp and have low noise, which is not particularly suitable for lyric pop music performance.

& lt3 & gtR50。 To be honest, MD didn't play much before. Just two models, RH 1 and DS77, impressed me well. The voice of MD can be described as exquisite. Especially RH 1 for a long time. It depends on the comparison between UFO and RH 1. Please refer to my previous review post /viewthread.php? tid=605 198。 Highlight =. Speaking of getting the R50 for the first time, the workmanship and materials, that's my impression of Sony. To tell the truth, the analysis of R50 is not as good as RH 1, and the noise is not small, but the sound is really good. Temperature, full of emotion. The sense of encirclement is really good. Accustomed to digital sounds like RH 1, they suddenly changed to R50. It's refreshing Yes, this is music appreciation. Warm and low noise, as if returning to the joy and happiness of listening to tape recorders in the 1990 s. At low frequencies, R50 also performed well, with no deep dive and good elasticity, but at low frequencies, it seems to find a balance between quality and quantity. This may be the so-called "simulated taste". Of course, the analysis of R50 is still a weakness, and the background is divorced from human voice rather than very good. The separation of musical instruments is still a lot worse. On the sound field, it is still much worse than the first two. Overall, the R50 is definitely worth listening to. After all, it's only over 300 yuan now, which is much better than the MP3 which is about 1000 on the market. Of course, you have to put up with the trouble of optical fiber recording.

& lt4 & gtIpod Classic。 IPC should take the most photos, but needless to say, I believe it has the most people. Exquisite workmanship, fashionable appearance, simple operation, and a large capacity of 120G, almost despise everything else in terms of comprehensive quality, of course, domestic shanzhai is not counted. Let's talk about sound quality performance first. The real IPC is definitely not as "rubbish" as the people who filmed it. On the whole, the sound is quite satisfactory, with little coloring and good analysis. To put it mildly, it is a true reduction, and it smells like listening; To put it bluntly, it is plain boiled water, not boring. High-frequency, a word can be described as bright, usually sustained, and it is really easy to break when the volume is high. Intermediate frequency, cold and thin, surround feeling is actually very good. As for the low frequency, many people think that IPC low frequency is almost disabled and too few. In fact, diving is not bad, and flexibility is also ok. Therefore, using a good plug with medium and low frequency has a good effect. For example, 5PRO, UM2, etc. The sound field is still good, at least it is true, not fake at all, not empty. I think it's very good. Of course, don't compare with flying saucers. Finally, I want to say that what IPC wants is comprehensive quality. The sound quality is good, and medium is enough. I really want to play. LO's handwriting has improved a lot
