Let’s analyze this sing-and-play

When I first heard that Pumpkin was about to sing and replay, I didn''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t take it seriously. Although the PL-P''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s vocal and amplifier part was praised by many fans, and I also used the VPS vocal amplifier that was born out of the legendary PL-P circuit, until now I still think that VPS is a good value for money. The circuit design of the booster cow plus two vacuum tubes and subsequent transistor amplifiers is simple, plus the precision production of the pumpkin sign. It is important to know that the micro-signal amplifiers such as vocal amplifiers have extremely strict requirements for components and circuits. If your budget has requirements, this is definitely the best choice for reference. Of course, if you are pursuing the ultimate, it is another matter. After all, a problem with VPS is that the total gain of 60dB is not high compared to the 70dB of crystal movement. This has certain requirements for the front and rear stages, especially when using low output cartridges. It is often that the sound suppression is not dynamic enough, so the adaptability of the VPS should be considered for the front and rear ends. For most people, this is the Lexus ES in the car. The design style is soft and moderate. This is the choice of most people. Of course, if you mind the feeling of dripping floor oil that CVT lacks, this is not yours. Dishes.

For many years of playing with equipment, from playing to the ultimate pleasure to satisfying the senses of sight and hearing with purpose, I have taken it calmly. From the pursuit of high analytical power and high-density quality, I feel like the slightly nasty style of analog equipment, and the singing and playing have also changed from Gaowen 3.8 and CH''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s P1 to contacting the antique bird booster and full daring singing and playing. I firmly believe that vinyl is like this. It’s the right way to use sing-and-play programs like Boost Niu and Quandan. As a traditional vinyl amplification method, mm vocal amplifier plus booster cattle, almost all high-end cartridge manuals will be nominally load impedence, in fact, this indicator is designed for the choice of booster cattle. In the actual match, through a reasonable booster, my phono cartridges have bloomed with potentials that I hadn''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t heard before. The single booster cow paired with full guts and amplifiers is also facing a particularly stringent connection and matching problem. I am not too accepting of the excessively dark and strong low-frequency tone and appearance of the antique equipment. After all, as a man who has just entered middle age , Just like the new 997 if you like the Porsche 911, just like the sophisticated mechanical design and a little bit of historical feelings, and it has not reached the old age of completely retiring to the pastoral. Therefore, I have been paying close attention to the full-blown singing and playing of the newly designed booster cow.

After all, vinyl is something traditionally simulated for decades, and each has its own insights and secrets. You can also think that this is the refinement of backward technology. With so many kinds of cartridges on the market, different voltages need to correspond to different gains and impedances. Transistor phono amplifiers are easy to make cartridge amplifiers that can correspond to different voltage impedances. Transistor IC and other technologies have made rapid progress. Transistor IC structure Phono amplifiers have become the mainstream of current phono amplifiers. Except for the astronomical 300,000-level FM223 with its own modules, the 100,000-level Gawain 3.8, CH P1, and Jialong’s KP1 all use IC. However, compared with the full analog singing and playing of the bravery amplifier + booster cattle, it is like the difference between digital and analog. It is not to judge the sound quality, but you like the cup of tea.

I tried to listen to EMT JPA66 in different systems of my friends. It won my heart. It has two built-in boosters and four cartridge inputs, each group can be adjusted independently, various equalization curves, and the exaggeration is that there are worn records. The denoising function, if you need a phono player, if financial ability permits, I strongly recommend EMT JPA66,（Gain: MM 53 dB; MC 73 dB, MM is 53 dB, which is much higher than the average. Use vacuum tube: 6 ECC803; 2 ECC99）The curves of RIAA, London ffrr, Columbia, and EMT can be customized and have powerful functions. They use non-band adjustment curves. The curve adjustment parameters have to be familiar with the thick manual. The fun is that you can also plan the curve yourself. However, I still find it difficult to accept the unique appearance and complicated adjustments. After all, I didn''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t have many front pages in the 1950s and 1960s, and I didn''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t want to contribute to the hype. Of course, it can also be said that price is also the most influential factor.

Recently, the same delicious crab changed from Gawain 3.8 to Classic Phono, and the evaluation was very high. I paid attention to the non-frightening appearance of this vocal and amplifier parameter data: a new generation of patented booster cow provides 16dB gain, four Vacuum tube-two E88CC/6922, one ECC81/B739 and one ECC83/B759 composed of a new class A circuit pure bile amplifier architecture, MM gain maximum 48dB, MC phono amplifier total gain up to 64dB! Two sets of inputs（MC/ MM with booster bull, MM without booster bull can also purchase MC version separately）; Customizable impedance load adaptation.

And for the front page or old version of the record playback needs, the front panel is humanized and more convenient to choose the RIAA, Teldec and Columbia curves; and the stereo/mono selector on the front panel is compatible with mono in true mono mode Phono cartridge; and you can easily choose the adjustable high and low gain on the front panel: for MC input, the gain option is 54/64dB, for MM input, the gain option is 38/48dB. You can also use his family''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s unique virtual battery technology power supply. As Jia Bing said—“Pretty”!

There should be applause here…It can be said that it is a sing-and-play model that satisfies my ideals.

First of all, as mentioned earlier, I think the sing-and-play program like Boost Niu and Quandan is the right way. The NAGRA manufacturer specifically mentioned that this booster cow is based on the core technology of the HD preamp. The HD preamp adopts the most difficult cow output volume design. The manufacturer has developed this technology for two years, and it is necessary to circumvent such a volume output cow. Veteran workers for a week. Needless to say the effect, the transparency and dynamics of the HD pre-stage will subvert your understanding of the output. By the way, since the moon landing project, NAGRA has been supplying transformers for aerospace and spy equipment. This is also a disdain for the heroes, so I never doubt the strength of Pumpkin Bull.

As for the MM pure bile amplification part, four bile ducts with two-stage amplification provide 48dB. Like AN, the Russian military-grade bladder selected by the manufacturer is used. Genalex 6922 Golden Lion Golden Foot is also a contemporary famous bladder. Many manufacturers are now using the currently available ones. After all, manufacturers are pursuing the quality consistency of mass production. Many tube enthusiasts like to change the tube. As the saying goes, changing the tube is like changing the machine. Pursuing different styles and flavors is also one of the fun. The sound is indeed the most balanced.

It is worth mentioning that the high-gain and very good signal-to-noise ratio vocal amplifiers are almost all sky-high prices, not to mention that more so-called sky-high price machines can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t do it, so the general vocal amplifiers don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t dare to do it. Too high, it seems that many high-end phono amplifiers are stingy in gain, and the FM223 with more than 300,000 phono amplifiers only has 62db MC. Transistors are like this, it is conceivable that the amplifier can do a good job of difficulty. The output of the VPS before the pumpkin is only 60 db even if it uses a bile amplifier plus a transistor amplifier. It may be compromised because of the signal-to-noise ratio and hum problems. The output of the Classic Phono with full MM amplifier is medium, MM 48db, MC 64db, which can be considered very good, the gain of the vocal amplifier must exceed 65db and the background can be clean. It is really not easy. I have a sense of the quietness of the vinyl vocal amplifier. It is almost a persistent requirement, so that the style of the cartridge and tonearm can be faithfully restored and displayed. In the actual listening experience, Classic Phono does have an unusually peaceful and deep background that impresses me. It''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s like facing the sea, with spring flowers blooming, and looking far away, it''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s as comfortable as the wind and the clouds.

Let me talk about the sound aesthetics design concept. Some people may like the strong taste of guts, but I do like the concept of pumpkins. I treat the tube machine as a transistor machine, and there is not too obvious the deliberate thickening of the tube machine. The warm sound at first sounds like a mixture of tube amplifiers and stone machines, each with its advantages, transparency, large scenes, many details, bright, open and slightly bright colors. There are emotions that mimic people''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s hearts. It''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s like a scumbag man in a suit driving a 911 makes it hard for a woman to control himself.

I believe it can also be seen from the open-opening photos that the materials inside have been coveted, various sound tuning secrets are huge and unique cross-connected capacitors and filter capacitors, and multiple sets of precision machine voltage stabilized high-voltage circuits with independent left and right channels are quite good. Ingenuity. Maybe there is a debate about the different sound colors between the bile rectification and the transistor rectification, but in the occasion of the ultra-high requirements of singing and playing, I absolutely agree with the transistor rectification. Pumpkin advertises that his family uses a medical-grade power supply design. Consider.

Speaking of power, the pumpkin machine can also be powered by his exclusive virtual battery! The benefit of battery power for the phono is self-evident. The quietness provided by direct current can be even better. What is virtual battery power? It is the use of super capacitors to form a large-scale power storage, which can provide a steady stream of power without compression. At present, Tesla and other electric vehicles are researching in this direction. The power management system of super capacitors is a problem. Pumpkin is developing flagship This technology was successfully developed during pre-decoding. The increase in gain and the improvement of power supply make Classic Phono expressive, the sense of texture and density is real and natural, the sense of abundant energy and the dynamic sense of flexibility are impressive. The shortcomings of his VPS pales in comparison.

As a high-priced vocal amplifier, this time the pumpkin provides curve selection and mono selection as well as high and low gain options on the front panel. It is convenient to use. I won''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t say more if there are not many mediaeval records. Although the records released in the middle and late stages of the vinyl era were recorded according to the RIAA curve, and then used RIAA to sing for loading and playback, several major record companies still use their own curves in the later stages, such as the Columbia curve of CBS, and DECCA also has its own curve. , And so on, there are seven or eight kinds. Among the more stubborn companies such as CBS, the records released in the 1980s still use the Columbia curve, and the vinyl records produced by CBS can be said to account for half of the sky.

Friends who play second-hand records may prefer to play with curves. There are about 23 types of vinyl equalization curves, and there are three to four commonly used ones. They are RIAA of the American Recording Industry Chamber of Commerce and FFSS of DECCA Records in the United Kingdom, Columbia Records and Columbia Records, the predecessor of CBS. The European AES standard. A further step is to add another arm with a monophonic cartridge. There are several other equalization curves for monophonic. Friends who like middle-aged vinyl can try 33CX, paparazzi and other different curves MONO to demonstrate. These are already in the archaeological category haha. I was deterred from looking at the pit. In addition, the curve is complicated and difficult to deal with. The curves used by different record companies in different periods have not been publicly documented, so the best way is to try to listen to the effects of different curves and find the most correct option for your own system. Just record it. Gawain 3.8 is simply RIAA, which is probably reasonable. In addition, I’m surprised that Classic Phono doesn’t have an inverting function, as it has a decoder in his home.

Speaking of load impedence at the input of the phono amplifier, since ancient times, MM cartridges have been using 47KΩOf course, earlier machines can also see 50K or 100K, etc., the load impedance of the early MC cartridges, many phono manufacturers like to set it at 100ΩOr 30, 50ΩProbably the popular Ortofon low internal resistance MC cartridge was also followed by many MC cartridge manufacturers. It is undeniable that the subsequent MC cartridge adjustments with different load impedances can indeed change the sound and even find a personal sweet spot. Of course, if the system or cartridge is connected to different load impedances and no difference can be heard, or no matter what load impedance is connected, it is good to hear, then there is no need to spend a lot of time to adjust, you can sit down and listen to the music.

Impedance adjustment of the cartridge, the original factory only attaches five sets of impedance adjustment modules, the minimum is 100Ω, If the recommended impedance of the cartridge in your hand does not have the above value, use it with a resistor. Because the more contacts and solder joints, the higher the inductance will be detrimental to the high frequency. You can use blue and green Vishay/Dale''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s low-noise and high-precision metal film resistors, or simply come back to Kondo''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s silver resistors. Of course, the most important thing is to first measure the resistance of the left and right channels with an electric meter, and then it is OK.

Good equipment is a work of industrial design, manufacturing technology and sound aesthetics. The pumpkin is undoubtedly the best model. In terms of listening, I finally understand why the fellow is changing doors at the same level. It is indeed in the tranquility and sound field. It depicts the same grade of transistor vocals and amplifiers, and it has the unique gorgeous colors of tube amplifiers and the exquisite appearance of pumpkins, which is impeccable. I think the agency should increase its promotion efforts, and wait time for the users, it will surely let people know its powerful qualities. Let us wait and see!
