In the second half of 2016, Sony released two flagship players, WM1Z and WM1A, and the Walkman finally has the equivalent of the IRIVER AK flagship, the $1500-3000 models. These two players are also called black brick and gold brick. But we are not evaluating them today. The emergence of black brick has also left Sony with a large price vacuum between its own product line, until the launch of the ...
In the low-end market, Sony’s one year one update strategy plays really strong, not only a year more than a price cut speed. Sony just two months ago just released the A50 series of players to replace a year ago launched the A40 series to become a new generation of 200-dollar products, the most entry-level model NW-A55 although the listing price of 1499 yuan. I’ve only been on Sonystyle’s website for half a month and Devalued 40 bucks! But in fact, it is reasonable, after all, in the middle of this year, the A45’s formal channel price has been reduced to less than 150 bucks.
I wonder if you remember the A45 to A35 upgrade? Let’s do a simple review. A45 officially announces support for MQA decoding, or MQA Core, which is exactly MQA Core, which can restore MQA to level 2 folding and plays MQA content at 88.2kHz or 96kHz sample rates. The final MQA decoding can be achieved with the USB DAC external ity of mQA Core. We’ve had validation before. But interestingly, the A35 is also supported. The big change is that the A45 supports the USB DAC sound card function. The HN suffix comes standard with the active noise reduction feature of the headphone player set, a45HN certainly upgraded, but we didn’t buy a bad review.
The A35 was indeed the A35HN, and the active noise reduction performance was somewhat disappointing because there was a setback compared to the previous generation.
The A55’s upgrade seems to be more pronounced than the A45’s. For example, the look style and size are the same, but all redesigned, the details are more consistent with the ZX300. A closer look at the photos shows, for example, that the A55 has a larger curved design on both sides, and that the control side buttons are changed to a circular button as much as possible, which looks more like the ZX300. And the thickness of the metal body does seem to be a little thicker than the A45, the surface oxidation process is not like the A45 pursues a matte texture, and show a brighter and more metallic texture of the design, so the A55 in the coming winter will certainly feel much cooler than the A45.
In terms of function, the A55 also supports the ad45 on the official new addition of MQA, APE and other functions. The most distinctive feature on the A55 is the sound of the vinyl record processor. The official introduction describes the effectdevice as: “1. Low frequency resonance through sound pickers; 2. fine surface noise and scratch noise; 3. Rich sound generated by acoustic feedback from speakers to turntables.” More interestingly, on the Sony Special Note A Series below, the effect has only the on and off options. That is to say, the future ZX series, WM1 series will have a richer set, you can look forward to.
The vinyl effector is a subjective point HiFi metaphysics effect, the general HiFi world believes that the black glue record’s charm in the unique undertone is indeed one of the important factors. For example, in a room in a modern city or in a top-of-the-line concert hall, there’s actually a little low-frequency noise when we feel quiet, and this can be verified with the use of active noise-cancelling headphones. The way vinyl records work is just as good as this kind of natural undertone, which is actually included in vinyl production and recording. As for sony’s second point, making scratches and frying beans? In fact, Sony this effectdevice added is also extremely weak, basically inaudible, much less than we heard some deliberately added to the sound of fried beans of modern recordings much less. If the first low-frequency resonance and bottom noise are recognized by burning friends, then the second high-frequency sand sound is certainly not a good thing. And when you use a better needle, with a very clean record, there’s really no part of the sound. As for the third point, I don’t know what it means.
As for the charm of vinyl records, it’s not clear here, maybe the next time you write Sony’s richer effects, you can chat. But the black rubber record equipment burning money is really very strong, to get a realgood low frequency is not 1-2 million can achieve, very heavy turntable and light shock absorption system on low frequency, dynamic, relaxed impact is still quite huge.
About the main functions and software parts of the player do not do too much introduction, and A45 and before the player is not very different, the current Sony this set of UI performance is good, easy to get started, especially during playback scrolldown after the sound switching settings interface is still quite convenient for the player to operate.
Remember before the test A35, A45 when there are netizens message said that Sony’s frequency curve high frequency up the problem is not loaded? This time we added 300 Euro headphone real load to do a set of data. It does nittreally sensitive to frequency changes after the load of the digital amplifier, but that doesn’t seem to apply to Sony.
From the objective data point of view, the A55 performance of the right moment, in line with the Sony player in the last two or three years A series of standards, frequency scanning characteristics have basically no change. Under a load of 300 euros, the upward trend of high frequency around 17kHz is independent of the load and empty load. There seems to be a problem with the frequency scanning of 96kHz. This is because we see 44.1kHz above 18kHz part of the frequency curve up, and to 96kHz sample rate signal is 20Hz-48kHz, the same trend upward, we have done a lot of output voltage attenuation, but should still have a bit of an impact. It should be noted that although high frequencies all have an upward trend, the 96kHz noise problem is not on the ZX300, basically the same on the A45 as the A55.
Let’s look at the more interesting look at the objective data of the vinyl record effector. The vinyl effectr will add a constant undertone in the lower low frequency part, such as frequency scanning can be seen, in the horizontal coordinates are very low position has a constant red color of a constant, the signal strength is not weak, but because the frequency is very low plus the human ear hearing curve, this part of the perception is weak, actually not strong. We also did the frequency analysis of this part of the signal, the strongest part of the signal is about 20-40Hz, the effective range is about 100Hz or less. Here to review Sony’s DC phase simulator low-frequency effect, from the perspective of the frequency domain, it slightly enhances the frequency of the low-frequency section, while the left and right channels of the low frequency to do a string. The vinyl effector, on the other hand, generates a constant special undertone noise at low frequencies, allowing the undertone to react with the signal.
Of course, the vinyl effectr in the high-frequency part also did a little deliberately add the rub sound processing, this feature is very very light, basically can not hear.
Overall, the Sony A55’s subjective hearing, output power and volume output gear settings are no different from the A45. However, there seems to be a little nuance in the subjective hearing aspect, that is, the Sound Density and dynamics of the A55 seem to be so good, mainly in the middle and high frequency part of the sound junction is more clear, three-dimensional, of course, very small.
Next, let’s start with the main hearing of the vinyl effector. When the A55’s vinyl effector is turned on, it can really affect the style of the entire sound, of course, the main part is that the sound in the lower parts of the medium frequency will feel a little softer, and the vocals will sound milder. You can’t hear a constant low frequency buzzing like shown in the chart above while listening to music, or it’s probably too low to detect. But this undertone, or Sony’s effector, really changes the a55’s low frequency when it’s turned on. It and the DC phase simulation effect is not the same, the DC phase effectr is still somewhat so that low frequency becomes rich, more sense of weight, and the transient becomes slower. But the black encased simulator makes the low frequency become soft, the volume increase is very small, so that the low frequency space sense slightly improved, so that the speed of the low frequency elasticity shows a soft and soft listening. This simulation is really special, and for most music there is certainly no negative impact under the A55.
This test we should have recorded a piece of vinyl effecter playback effect, it may take a few days we will be alone, will be notified on the official microblog. At present, the vinyl effectr is still very fun, quite useful a setting. Although Sony has significantly improved the sophistication of the S-Master in terms of high frequency since the beginning of nearly three years, making the sound neutral, delicate, and the high-frequency relaxed without burrs. But even with the density and dynamics of the Brics sound still apart from top-of-the-line devices, Sony also realizes that something more HiFi should really favor a warm, loose, layered trend. You can obviously hear that “brick” than “black brick” sound a lot warmer than the “hard-pressed I have to go to Wangfujing Sony store to listen to, you can also …, by the way to listen to So60,000 how much garbage?” ]。 And how do you pick a sound under S-Master?
Sony’s DC phase effectr and vinyl effectr are two subjective settings, objective data is certainly not good, but subjective listening is good, at least the positive effect is greater than the negative effect. For the sound details of the A55 player, you can refer to the A45 time assessment content, not specifically not to be made here. But make a summary. As a 1000-level entry player, Sony, although in terms of sound dynamics, thickness and even the extension of very high frequency, high-frequency density can not be comparable to the million-level or more than 5000 yuan equipment. But as the ring and electric headphones become more popular today, the optimization of the faster and hyperthercent becomes important, and Sony’s players do a good job of optimizing with these little earplugs.
Although its sound density, medium frequency dynamic thickness is not as good as many players using ESS DAC, but with the high-frequency detail performance, style optimization is in place, almost no burr, sound is not hard, this is some advanced sound card, the player may not be able to do.
Finally, the A55 features: 16GB of built-in storage, support LDAC . . . why not as android phone objective indicators? Because Sony’s LDAC does not do 96kHz up-rate, two-way USB DAC function, MQA Core external MQA, better use, stable software system. Compare the fun vinyl effector and dc phase effector.
