The title picture is the cover of "Memories" - Within Temptation, this song is a perfect match with the electrostatic headset MC9, poisoning has been deep In September last year, he came to a new environment, so he reconfigured a set of equipment. K712 + PCM1794 decoding + FL01 amp. Then many lucky friends who had the privilege to meet were invited to a party in Chengdu Tea House a few days ago and listened to some good equipment. The following is divided into three parts: K712, feel, FL series introduction. By the way, let's take a look at the DA-03A (PCM1794). Personally feel the original value of 400. Bring your own amp in general. Biliary output still has a significant effect. I have mainly changed the filter capacitor and the decoupling capacitor. Panasonic filter capacitors do a good job, the price is cheap, the effect of: AM Series> AU Series> M Series. Nichicon KZ does a great job of filtering, but the price is higher. RA3 filter is also a good choice, the price is higher than Panasonic, lower than KZ. ELNA SILMIC II is a deputy, sound fresh, not irritated. ===================================== Split Line=========== ========================== The K712 recently pushed by Aunt Zhang is an upgraded version of the K702. 702 If you don't push well, you will get a bad sound, but 712 won't. K712 direct push has a good effect, but the addition of decoding amp boost is also obvious. Here are the features High frequency: bright, but it feels like high pressure, so it won't be harsh. Unlike the K701, the high frequency is not harsh and the K712 won't be harsh even if it is not pushed. The other is that the high frequency is delicate and moist, and it is very comfortable when listening to traditional Chinese musical instruments. IF: Pushing vocals is a bit rough, and it improves significantly after the amp. Vocal thickness is just right. Headphones such as K240S and H600 are suitable for listening to mezzo-sopranos, because even if you use them to listen to young female voices, you can obviously feel how old you are. The thickness of 712 vocals is just good, so it is suitable for listening to songs of various ages. Low frequency: The volume is larger than 701. In addition, AKG's 7 series has a lot of low frequencies. The characteristic of the 7-series low frequency is clear image, accurate positioning, powerful diving, and suitable for listening to popular songs. HD600 low frequency is characterized by a good sense of atmosphere, but the overall amount is too much, the image is not as good as the 712, suitable for listening to the symphony of the atmosphere (large preparation). Compared with the K701, since both are 7-series, the same units are used, so the tuning style is very similar. Let's talk about the characteristics of the two headphones 701 features: Very distinctive mid-high frequency - creamy Yan value Faith (mio~!) Pushing is not good for low-frequency disability, and there are few amps that can be pushed well (FL01, SPL, SimAudio 430) Cheap 712 features: In the true sense of tri-band equalization, it is not the tri-band equalizer that is now being used badly. Good push, no need for 701 so big thrust can control well expensive Higher quality Direct push test: Equipment: Lenovo Y50 There was no feeling of listening to Meng Tingyun’s song with K240S before. It should be no push. Now with K712 suddenly heard the eyes light up, feeling the delicate characteristics of the K712 with a delicate female special match, may not be enough due to poisoning skills, can not describe the language, simple and nice. ===================================== Split Line=========== ========================== 1. A good set of headphones has no obvious disadvantages and no obvious features. After listening, it will not leave any deep impression, but it will feel very comfortable when you listen, and your body and mind will be relaxed. Perhaps this is what is often referred to as resistance. 2. A good set of headphones will have distinctive features. Such as the base point MC + MC13 combination, the female voice is very feminine, smooth, listening to "Memories" when fully demonstrated the charm of women. If you use pictures to describe: If this is a dynamic female voice So the feminine voice is Feel this is female poison, direct poisoning. 3. If you just want to improve your quality of life, a system costs 5000-6000 is enough. It can be said that spending 20% ​​of the money can get 80% of the experience, and the remaining 20% ​​of the experience to spend 80% of the money. A set of 1500 or so systems allows you to feel good positioning and resolution, but the tri-band is more or less flawed, such as high-frequency thorns, large amounts of low frequency, and mid-range thin. The 5,000 or so system is basically flawless, with emphasis on tuning. For example, AKG's 7 Series is suitable for listening to pop music and Chinese folk music. HD600 and HD650 are suitable for symphony and Chinese pop music of the 90s. Some people say that some people use DT880. Listening to the symphony has a magnificent feeling. This level of system has little difference in texture and tone from top-level systems, but there are some gaps in dynamics, control and atmosphere. The most obvious is the integration of sounds. More than 5,000 systems can clearly identify the location of each instrument, and the top-level system integrates these instruments on the basis. Each instrument can perform exactly. Tea room audition some equipment: MC13 Ragnarok Amp +AKG K1000 HD600: Sennheiser classic headphones, the latest black box packaging. MC9+MC13 suit: The feminine voice is smooth and feminine, and the other performances are general. YGG: top decoding, rich in detail, and resistant to hearing. ===================================== Split Line=========== ========================== You're right, right, here's the ad Things are too ugly, not on the map The style of this series is stimulating (high-frequency bright, low-frequency dive deep, dynamic large), of course, is the author's style. A few days ago, I used the FL41 decoder to connect to the MC13+MC9, and pushed the static earphone into a dynamic earphone... Just like the WIMA capacitor, as long as the system adds a series of products, the entire system will be affected. If you want to read and study quietly while listening to music, please ignore the following directly! The author produced the first pure Class A amp, FL01, last year to push AKG's 7 Series. In simple terms, it is able to put out the low frequency of 701, the amount is not large, but the full elastic low frequency, high frequency round and gorgeous, sound transparent, very good performance of the 7 Series style. It is a pity that we will stop production after the year. We must seize the time to start. The second work is FL11, a fully-split balanced amp designed specifically for the HD600. Since listening time is not long, you can only talk about it briefly. The atmosphere is very good and it will be a good experience to listen to the symphony. The high frequencies are not dark. The third work is FL41, PCM1704 + CS8416 decoding, the interface is CM102, can also be upgraded to CM6631. The interface is not very good, so it is recommended to use the coaxial input. Features are good texture and dynamic. Before comparing with the spring of Ares version. It can be said that both have their own characteristics. The characteristics of the spring is that the high frequency overtones are very rich and the atmosphere is good, but the low frequency positioning is not as good as 41. 41 with AKG 7 Series style, general atmosphere, low frequency positioning, high frequency overtones just right, big dynamics. In fact, the most important feature is that the IV conversion and LPF parts do not use single op amps or dual op amps like other decoders, but instead use discrete components to build up the amplifier circuit. Price, FL01 is 1198; FL11 is 1498; FL41 single-ended is 1198, balance is 1498, if it is not old customers plus 300, upgrade interface plus 150.

The first one: Meng Tingyun - The shy rose opens quietly
Second: He Xuntian - The songs of Qian Jiangyue test equipment, the front drum and muyu in this section of the performance of law-abiding, no shortcomings, positioning and dynamics have reached the basic requirements, 3 minutes and 20 seconds later joined the vocal, the dynamics are very large, this time the drum The sound became meat, the voice became weak, and the positioning was not clear. Explain that direct editing cannot listen to large-scale music.
Third: Now You See Me
The small establishment, overall performance is perfect, the transient rate has improved significantly compared to the K240S, especially in the 50 seconds to 60 seconds, a series of dense drums, the K240S sounds more messy in the case of enough thrust, and the K712 is Can be clearly identified, positioning is also relatively clear. Explain that in the case of direct push K712 can listen to some small music, experience is not bad.
Third: Mark Mothersbaugh - Pitch Perfect 2 End Credit Medley
In the electronic category, the high frequency is just like what was said before. It has more volume, no harshness, and low-frequency volume. At the same time, it does not cover other sounds, and various musical instruments can be truly restored. The overall feeling is transparent, strong sense of rhythm, not head.
Fourth: Huang Guojun - The wind blew up an old song, and the masculine baritone sang two people. When the chorus clarified the voices of two people clearly, it showed that there was a good performance in the analysis. Rely on the analysis to show masculinity. At the same time, the K712's IF sound is relatively small, that is, the kind of straightforward, can restore the vocals, which is related to the positioning of the monitor, and therefore does not perform very well vocal type, but also suitable for listening All kinds of vocals.
Fifth: Mao Amin - In love with Zhang Wuji soprano, is still a straightforward voice, straightforward to feel the changes in the singer's feelings, in this song is particularly prominent performance. It is a classic song, and the singing is really solid.
Sixth: Zhang Hanyun - sweet and sour is my young sweet beauty, full of vitality. Before using the zombie PR3002 to listen to this song more, I feel that PR3002 listen to Jane Zhang's voice sweeter, K712 less a sweet, restored the real voice. Explain that the K712 is not suitable for listening to female poisonous music. It may also be the reason for direct push. Later on the DAC will be evaluated again.
