If I say that Yidu is the most dedicated amp brand in the domestic HIFI and the most successful brand, I don't know if anyone will oppose it. Although Edu has never produced a real high-end amp , no matter whether it is a desktop or portable or gallstone machine, Edu's are worthy of the price.
But here I want to share with you a headphone amplifier that is destined to have no sales. This is the MT604 that was launched this year. It has a front and back stone architecture. The front stage is composed of four 6J1 tubes, and the rear stage is a transistor with an output power of up to 2000mW. The price is 980.
is wrong, the price of this architecture should be very attractive, you will know after reading it.
▲The appearance is the same as the amplifier , but this MT604 is smaller and more exquisite, and the depth of the body is narrower, which is the same width as the Huawei mate30 in my hand. . But it is not so light and thin. The thickness of the fuselage is close to 2 cm, and the metal material of the whole body is equipped with two red knobs.
▲The two eye-catching red knobs on the front of the fuselage actually adjust the volume, but they separate the left and right channels. In the middle are 4.4 balanced output, 4-core balanced output and 4.4 balanced input, nothing else, don't complain.
▲The back display of MT604 has only a pair of Canon balance input holes and nothing else. To use it, you have to equip a separate balance line.
▲Family portrait display, in addition to the manual and warranty card, only the power cord is included in the accessories.
▲It is displayed at the bottom of the fuselage. Four plastic feet can be seen on the smooth metal plate, and there is also an SN code in the lower left corner. This detail indicates that Yidu is really bigger.Began to pay attention to the details of circulation.
▲4 transistors show, for the initial burn, the transistor has a weakness that is easy to burn out, but I have confidence in Yidu's after-sales service. Besides, the architecture of this MT604 is not the first of its kind, but at this price, except for DIY players, no other manufacturer is willing to do it. It is an unpopular and niche thing, not to mention that those who play gallstone machines are also old and not bad. That little money, so my opinion is that in addition to popularizing work, Yidu is more about establishing its own line of gallstone machine amp products. If others disdain to do it, they will do it. Persevere and perhaps become a domestic amp." First".
Why do you put the quotation marks? I would say that the sound quality is the best, but it has the opportunity to become the brand with the largest sales or volume of domestic amps.
▲When sharing personal feelings, I will definitely think of someone complaining when they see the output holes of MT604, because there are only four-core balanced output and 4.4 balanced output holes, no 3.5 or 2.5 holes, The earphones with 4-pin holes are rare, and probably only the old ones who play with the cable may have them. Therefore, the personal listening experience of this article is limited to the 4.4 balanced output hole. The paired earphones are only the 8-unit conductor and the sho-ear. Sicui’s limited edition Lyra is mainly based on the former, because the former has 4 electrostatic units. I have tried it with Qianlongsheng QA390 before, and there are always some flaws in the high frequency.
▲Besides, we also need to know that this MT604 is a pure headphone amplifier. It is perfect if it can be equipped with pure decoding, but like pure headphone amplifiers, the pure decoding on the market is not Too much, let alone buy at an affordable price. Fortunately, I also have Century Gray’s Lark and Qianlongsheng QA390 in my home, both of which are decoding amps, but they can also be used as separate decoding. Here I have to praise these powerful amps and decoding all-in-ones. Someday they will make you feel that full functionality is not a bad thing.
▲But in order to follow the principle that the entire system is separated,So I chose Century Gray’s Lark, and I used NAD’s entry-level CD player for the sound source. The CD discs are expensive or cheap.
The whole system gives me the feeling that it is warm, stretched and atmospheric, the low-frequency instrumental music separation is quite good, and the whole layering and sound field are also exceptionally good. However, on these two pairs of headphones, although the low-frequency has a good dive depth, the sense of cohesion is not strong, and listening to rock-like percussion lacks a sense of volume.
For the male voice, the warmth of one ear, fullness and softness, natural analysis, good details, when listening to the eight eyes, whether it is ventilating or vibrato is quite natural, the overall feeling is solid, transparent and clear, but It's not the kind of clean, over-analyzed feeling.
The female voice is also quite steady, soft and warmer, but not as obvious as the male voice. During the audition, I was touched by the sound of Tsai Qin for the first time on the earphones. It has both the details and the whole, although the sound is stained. But it's nice, just listening to Tsai Qin on the audio, there is less texture in the tone, but you have to talk about the basic qualities of image and tooth sound, which are really good.
The high frequency part is mainly based on the shoal conductor as an example. It appears to be much more neutral than the mid-low frequency. The extension is obvious. The dynamics and transients are nothing to say. Although it is not bright and slightly thin, it is overall and the mid-low frequency. The same transparent, open sound field and obvious musical taste, it verifies the potential of the electrostatic unit to test the convention of the front end. Listening to Akana’s famous "Diabolus in Musica", I really feel that violin performance can be superb. The dynamics and transients are very natural, the sound is stable, and overtone is vivid. When Lao Shao recommended me to buy this CD, I was a little skeptical at the price of more than 100. I didn't listen to it a few times after I bought it. This time I felt it was worth buying.
▲ overall summary
Let’s talk back to the MT604 itself. In fact, I don’t know what level the configuration of four 6J1 tubes is, but it’s like this kind of scale. Of pure amps should not be able to find a second one,This is its unique attribute.
The price, workmanship, appearance, and sound quality of the product itself (we can only touch part of it) are all very sincere, but we have to admit the fact that there are too few people who can buy it.
is not only to be interested in gallstone machines, but also to have a decoder (preferably a pure decoder), you have to buy two XLR balanced cables, and you have to have suitable headphones. Naturally, not many people buy it after this round of screening. NS.
