NX7 this model I received together with the DX5 of the topping, compared to the freshly baked DX5 at that time, NX7 this has been on the market for a while the performance of the gadget let me quite surprised, after a search, I found that in addition to the hardware test of Professor Wolf, the whole network actually did not see any reviews... Good guys, there are two things I am cute to do, one is to write a model that has been discontinued and cannot be bought, and the other is to write an exclusive article on the whole network.
NX7 hardware test I do not intend to do, first of all, I am used to using the output of the machine body to let the AP receive the signal, this method of testing pure ear put is a bit troublesome (to put it bluntly is lazy), the other point is that the noise of the NX7 has been lower than the background noise of the APX555, not to mention my slag 525, the official used a special method in the test to get a rough value. Those interested in the detailed test can move to L7Audiolab to view it.
And there is no doubt that the current portable, entry-level pure ear amplifier has almost no market, Toppin chooses to do such a product at a price within a thousand yuan, I personally guess it is for two considerations, first of all, Toppin did not carry too much power in terms of carrying, since doing of course from the low price, but I myself am more inclined to another way of saying - perhaps Toppin thinks that NX7 has been enough to hang all the same types of products on the market, after all, its indicators in all aspects are said to be "the strongest on the surface" There was no problem.
In terms of product form, the NX7 sent to me by Takupin is blue, the texture of the actual workmanship is not bad, the color saturation is slightly higher, and there is a certain reflective effect, which is still slightly troublesome for me. The NX7 only supports single-ended inputs, but can output 4.4 balance and 2.5 balance, and does not have a single-ended headphone port. Seeing that someone here must have typed the word "false balance" according to the heart of the excitement, you are happy. The NX7 is very portable, very thin, and has a prominent treatment on both sides of the headphone port and the end of the potentiometer ID to prevent accidental contact and reduce wear and bending of the in-line plug. The other end of the ear amplifier has a three-compartment battery display and a Type-C charging port.
NX7 has some exaggerated and extremely outrageous parameters, such as 135dB dynamic range, less than 0.00007% THD+N, 32 ohms and 300 ohm load can reach 1800mW and 180mW output power respectively, these parameters are not to say integrated, any of which we have hardly seen in the portable HIFI market, and may only iFi's "pineapple" series can fight for the ultimate power.
Before starting to say the sound of NX7, there is a very important premise to tell everyone who grows grass NX7, that is, do not use the original to listen to the recording line, this voice on the recording line is said to be "ground stall level" are overestimating it, I even suggest that Takupin directly cancel this line from the package, or launch a cheaper package, after all, the sound of the 98 yuan of the next door Fei'ao 98 yuan is not bad. The sound of this original wiring is really too ugly, dry, thin, prickly, hard and other words gushed out of my mind, frightening me out of the drawer to find a diyy to make an ordinary silver-plated wire, the sound directly on the N grade, all aspects are normal. Although I believe that this line of record must not affect the test indicators, and the SMSL ear amplifier I used in the past has also sent this level of line, I think that if an engineer or marketing person listens to an ear with this line, he should take my advice, or cut some cost from somewhere else to change it.
Regarding the collocation of the recording line, I will not elaborate, whether you are going to choose the cheap Yangshi, Fei Ao, or add some money to buy the ddHiFi home Nyx line version, you will definitely get value for money, although NX7 sells 999, but its own ultra-high sound price ratio is actually worth everyone's investment in the recording line.
In terms of sound, in fact, it is still an expected "modern sound", the bottom is clean and transparent, the sound field is well-regulated, what kind of space scale it should be, there will be no obvious auditory bonus, but there are plates and eyes in the expression of vertical height and depth, which alone is already the level that many entry-level portable products cannot reach. Anyway, as a product of the topping product, the bottom noise is definitely not there, there is no low volume bias problem, whether it is worth buying, in fact, it all depends on whether the style is in line with your taste, and the quality is not to worry at all.
Modern sound or digital sound, in my case is not a derogatory term, just like digital systems and analog systems do not mean that there must be a specific sound style, NX7's modern sound mainly refers to "high transparency, attention to clarity and layering of the sound base, and a more restrained sense of atmosphere and thickness expression", in fact, if you like the early style of Yintemei or White Tooth Home users should be able to get what I am saying.
Although NX7 is a modern sound base, it still has a certain taste for the expression of popular vocals, and I think it is completely in line with the sound that the mainstream market likes now, and the balanced sound has a moderate sense of shape and body, and the vocal part is beautiful and beautiful, there is not too much sweetness, the vocal moisture and graininess account for about 70% and 30% respectively, for most of the Asian female vocals and Japanese ACG have a good balance. Instrumental performance I think is better than the vocals, although it is relatively restrained in the expression of the sense of atmosphere, will not give you additional processing in reverberation and overtones, but has a good dynamic performance, transient processing clean and neat, especially the high-frequency part can be called a fresh jump, it can be said that although the NX7 is small in size, but in the complex scene of the sense of calm does not lose a lot of high-end players - of course, this is also the pure ear amplifier to play the advantages of the place, in the consideration of cost performance, pure ear amplifier is always the choice of spending a small amount of money to do big things.
NX7 in the paper parameters of the power performance is fiercely powerful, but in the actual headset collocation is not up to many high-end headphones, such as ZMF's VC, Meze's Empyrean, its sound performance is not as good as Lepi P6Pro, Shanling M7 direct push, mainly lost in the spatial scale (mainly longitudinal and deep) and medium and high frequency control. With SIVGA's SV023, Senhai HD400Pro, NX7 and most of the ten thousand yuan machine can break the wrist, and even have some small advantages in transient and knot image, to know that this is only a 999 small ear amplifier after all.
Have to admit that now the pure ear amplifier has been and the mainstream HIFI market has gradually drifted away, but Tuopin with NX7 to the majority of pocket shy users to provide a super cost-effective sound quality solution, even if you do not have a decent player as a decoding, with a small tail of the Po mouth can also make a good sound, the three-stop gain provided for the earbuds and headwear have a wide range of adaptability, slightly younger modern sound color is also quite in line with a mainstream taste of the current portable market, Overall, I think it is very recommended, but remember to change the root to record ah~
