In the past, I played a very interesting gadget, but there were too many things to play recently. Before it was popular, I wrote it first. I've been free recently, write this thing.
Perot d2p_ Taobao search Jingdong, Amazon, Tmall and other b2c no sale, put Taobao link s.taobao.com direct link This time it was Sunpo's digital amplifier d2p. The author of this gadget is Laojiao. The original price was around 600. Before his home was sold out, he sold 299, and now it looks like it is sold out. All three parties are selling.
â–² This product is d2p, very small, two palm large, looks very humble, but the weight is heavy, the whole body is all metal, the material is very solid. Also don't look at it small, but it has a 4W output of 50W per channel, you can push the small 6-inch 86db box to the sound of the day, and you can say that the sound pressure is at least.
â–² There are two knobs on the front of the fuselage that can be pressed/rotated. The left knob is used to switch the input, the rotation is to adjust the low frequency, the right knob is pressed to mute, and the rotation is to adjust the volume. The small black bar in the middle is the screen.
â–² The left side of the back of the machine is a set of RCA input, the top is the bell mouth, below the USB and rca coaxial input, there are 24v DC input and power switch. It is a pity that d2p has no optical fiber input, and it is even more troublesome for televisions. In addition, d2p adopts external power supply, random distribution is a small switching power supply, you can replace it with a linear power supply, and the sound quality after the replacement has a certain increase. Need to Tucao what is the switch power switch feel bad and use a long time is easy to malfunction, switch to the "off" position on the machine can not close, need to click in order to ok.
As a digital power amplifier, as the name suggests, the d2p machine does not have a DA section and directly amplifies the digital signal. Finally, it directly drives the speaker through the filter output. I am not quite sure about the specific circuit design. The analog input part seems to be doing AD conversion. Therefore, the quality of the front-end filter is relatively strong. After I tested the mojo and 4040 access, the style gap is far greater than the quality gap. Instead, the reaction to the digital source is very intuitive, using its own usb, entry-level interface Pearl 2 and top-level interface int204, the sound changes greatly, and the built-in usb effect is poor, unless it is not concerned about the sound quality is not recommended. In view of the relatively low prices of things themselves, individuals are more recommended with the digital interface, 2,730u, this cheaper digital interface, the price balance.
â–² The next step is to destroy the three views. After listening to this thing, I think my three views are a bit confusing, and then I found a few small partners to destroy three views together. The object of comparison is three digital amplifiers, namely the Divali 120, Ganlong 690 and Perth D2P, with prices of 39,800 and 3,980, respectively. . . And 299. The digital source uses the weiss int204, and the digital input is directly applied to three digital amplifiers. The speaker uses the atohm GT1.0V Divali customized version and the MAXX.
The final result. . . Anyway, we three people are broken up by three views. . . The prices of these three are nearly 100 times lower than the highest ones. It can't be said that the sound is similar, and its practicality is still able to hear the difference. Dari's density and control are obviously superior, but at least d2p and 690 are in the GT1V. The gap is small, because the MAXX and gt1 are all high-sensitivity speakers, the 690's 180W high power can not play an advantage, but d2p's sound is more sweet, with GT1 listen to Teresa is very moist, even Divali They are all inferior. Especially when pushing maxx, the advantages of Divali were further reduced due to the ambiguity of the boxes. Considering the comprehensive price point, personally feel that the price/performance ratio of d2p is excellent.
Compared with cheap goods, such as Weiliang's 99 yuan small power amplifier, friends just bought one and brought it to play. After connecting to the system, the sound is lumpy, the transparency is very poor, and the high frequency and bluntness are really. Unbearable, we did not even feel more careful to compare with one another.
â–² I put a recording here and use the tripod on the LS100 to record it. Everyone listens to it and destroys the three views together. There are five songs, five recordings, and three recordings in each group. Note that 123 in each group is random and there is no rule to follow. The 1 in the first tune and 1 in the second tune are not necessarily the same machine. Everyone who is interested can go and listen to guess. Friends who have heard before can also listen to it again, because I have re-ordered the order, so guessing in the previous order does not work.
In addition, this kind of recording may not necessarily reflect the real situation of the equipment and is only for entertainment.

▲In addition, I have to say that this little thing is really interesting. Its rated input power is 24V, but because the power supply is broken, I use the 18V power supplied by the Jungwe Power Supply and can use it normally. . . Then I tried the 8.4V lithium battery pack and it still worked. . . And the sound quality is not too severely degraded, that is, it is easily distorted when the sound pressure is particularly high. With a great deal of volume, 4 songs haven’t dropped out. After the visual test, they can become a generation of square dancing weapon.
Perot d5n_ Taobao search Jingdong, Amazon, Tmall and other b2c no sale, put Taobao link s.taobao.com direct link â–² After being completely destroyed by D2P, I had a keen interest in Perth's digital power amplifier. Just as his home D5N is also clearing, the original price is 1000+, now the clearance price of 678 postage to pay. The power of the d5n is 4 Euro per channel, 100W, which is twice as large as d2p. Just like Lang Quan, I bought one.
â–² D5N's packaging is very simple, is a kraft paper box.
â–² The box has foam shock absorption.
â–² inside a host, a remote control, a power cord. The D5N's remote control had a tantrum, d2p's remote control was metal, and the texture was much better, but the D5N feels so bad. . .
â–²D5N is much larger than D2P. Personally I think that part of the reason is D5N's built-in power supply. There is only one knob on the front of the fuselage and a small screen next to the knob. This knob can still be pressed and rotated, press to switch input, and rotation to adjust volume. Silencing can only be done by remote control.
â–² At the top of the back is the bell mouth, below from left to right are a set of RCA analog input, optical fiber input, RCA coaxial input, normal/movie mode switch button, the rightmost is the switch and power jack. For power supplies, the d5p uses a built-in power supply, eliminating the need for an external power supply. D5n adds fiber input compared to d2p but lacks USB input. Taking into account d2p that bad usb, it is not worth mentioning. However, d2p that usb support mobile phone otg, and win is also free drive, if it is for the elderly home to do multimedia use is still quite convenient.
Compared to d2p, d5n is twice as powerful and can accommodate more speakers. In general, d5n can be driven when the sensitivity is higher than 86db and the size is less than 6.5. My family has a small 6.5-inch landing on the 6 Euro 89db, d5n can push it to make do, at least sound pressure and low frequencies are OK. The 83db box, such as the rain after the p3 or ls35a is very difficult, relatively low frequency, small seven such a closed box even more delusions, can only say push. However, in terms of its price, I lent some friends to play, and the effect was quite subversive. They really did not expect such a cheap gadget to have such an effect. There was an old one that bought one directly. . . Use to watch movies. . .
Whether it is driving gt1 or maxx, d5n is better than d2p's low frequency and dynamics. It is not known whether the power is improved or the effect of better circuit design. Listeningly, d5n is softer than d2p. The high frequency is less rough and grainy. The female voice is even more sweet. In general, d5n is still stronger than d2p, and meets the original pricing of d2p and d5n.
â–² d5n power is 4 Euro 100W equivalent to 8 Euro is almost 50W, Lang Quan 50A power is 8 Euro 55W, both the power is close. Using the same decoder to simulate the input, Langquan's flavor and sound field depth will be slightly better, but the sound is relatively soft, and the speed is relatively slow, d5n sound is more clean and transparent, better analysis, a lot faster, low-frequency more solid . After d5n changed to 204, the transparency and speed were improved, and the resolution was greatly enhanced, but the taste became more straightforward and the sound field became flatter. The two can be said to have merits and demerits. If you listen to songs, Langquan will be better. If you look at movies, d5n will be better. Longquan's original price is 6k+, and the number of second-hand items is also more than 3,000. To be honest, there are not a total defeat of several hundred pieces of the game, and in some respects, it is still relatively uncommon to win. And whether it is d2p, d5n, qa690 or Divali, there is a common trait that the sound is very clean and transparent, the resolution is excellent, the speed is fast, and the low-frequency is solid. This may also be the commonality of digital amplifiers, compared to cheap traditional amplifiers. The advantages of these aspects are still quite obvious.
In general, these two gadgets are very cheap and effective. They are good value for money and are worth recommending, especially for beginners. Since d2p has no concessions in the near future, and d5n is still in the clearance, individuals still recommend d5n more for a higher price/performance ratio. However, d2p also has its own advantages, such as carrying its own usb. If it is to the elderly or their own bedroom multimedia, but more than the pursuit of sound quality, then directly use the d2p original switch power supply usb to connect the phone and pc will be very convenient, and that my d2p in the old wife's study service. The use of the living room in particular needs to be connected to the TV. d5n is more appropriate.
