Hifi circles the old cannon's favorite "coward machine."
We took an inventory of the newly listed electro-channel audio products in 2024, excluding traditional desktops, and we found that there were many portable electronic audio products last year. Such as the extent of the use of traditional electronic tubes
Xd05 t, abso
Nunchaku, ali and
Sp3000t and kai's
N3 ultra; there are also daring products such as oprah4 and c9ii using new electronic tubes。
In the traditional hifi circles, the courage machine has always occupied a special position, and its work has a retrospect of technology. And when that warm light rises, the electron in the glass shell becomes active, and an incomprehensible and wonderful feeling emerges, that's the charm unique to the tubes. Even today, where transistors and integrated circuits are prevalent, the electrode is still warm in the hifi domain, and the old fever often describes it as a warm, intoxicating “bold” for music, ensnaring countless burning friends。
But what's the word "courage" in old guns? Does it really exist? It really makes music more natural, warm, nice
Or is the so-called "courage" just a trick that the jss crafted in order to empty the electronic tube's inventory, or is it a psychological hint that the fever friends hypnotize themselves
So what's the word "boldness"? How did it come
"courage" comes from a unique and rich occasional tune
1. The non-linear properties of the electronic tube will have more occasional rhythms:
The unique structure of an electronic tube gives it some non-linear properties in the process of magnifying the signal. It is significantly less non-linear than a transistor. The current magnification factor of the transistor is expected to change significantly at different work points, resulting in a signal becoming more likely to produce an oddly high frequency during the magnification。
In relative terms, the proportion of occasional waves in the total band increases. This is a way to make the picture more harmonious by reducing the number of colours in a painting and highlighting the main colour mix。
2. The rich occasional waves have the same tone as music:
Due to the non-linear characteristics of the tubes, when the signal passes through a non-linear component, the original pure audio signal waveform occurs. According to the fourier class theory, any periodic non-sine signals can be broken down into a series of multiples of the original signal frequency (basic frequency) of a series of different frequencies and ranges of sine waves, which are coordinated waves。
Among them, the synergetic wave with a frequency of more than one factor of the base frequency is referred to as an occasional tuning wave, which happens to be eight degrees in the performance of the music, with the same or similar tone as the tone of the cylindrical sound, e. G., if the cylindrical frequency is 100hz, there is an occasional tuning of 200 hz (second tuning), 400 hz (four tuning). These occasional rhythms, which overlap with the base frequency, enrich the spectrum of sound and add a unique hymn to music, while transistors are easily produced。
The delay in the output transformer makes the rhythm of the music more comfortable:
The craft's output transformer is a key component for achieving resistance to transformation and signal transmission, and its design and quality also have an important impact on the formation of the “colour”. The iron-heart magnetism of the output transformer can cause some delay and distortion in the transmission of the signal, but such delay and distortion can make the sound more round, softer, and increase the level and spatial sense of the sound。
So, the “courage” in the old cannon mouth is based on the fact that the charlatan can produce more occasional waves than the stoner, which are sometimes associated with music, along with different types of cholesterol circuits, electronic tubes, capacitors, electrical resistance, etc., and different wiring methods, which combine to bring about the charlatan-specific “courage”, which is warm, loose, and thicker than the stoner。
It's only when you've got the guts and the stones and the voices are more diverse
The traditional cholesterol sounds are warm, thick, rich in musical detail and rich in the smell of music, especially in the medium-frequency segment, where the voice is reduced to a high level, giving people a sense of being at home。
The traditional stone machine sounds are characterized by high resolution, clear and clean voices that can accurately reverse the sound details. The performance of low-frequency and high-frequency (hf) is better, the low frequency is strong and robust, the hf is extended and can easily cope with large dynamic musical scenes such as symphony. Some, however, consider the sound of the stone machine to be relatively cold and lacking the warm music of the bold machine。
In the past two years, a hybrid circuit that combines a galler with a rocker circuit advantage, a transistor, has given a new choice to feverish friends. Not only is there an advantage in the size of the stone machine on desktop equipment, but there is also a bolder-specific ecd magnification advantage. Such circuits can also be miniaturized, with more options for those friends with limited space or who want to experience “goldness”。
The gallstone mixer combines warm sound and transistor tubes with high resolution and large dynamic performance. Music is played with a medium frequency of glitter from an electronic tube, which gives a good voice, and a strong low frequency and a clear high frequency from a transistor。
The iron triangle's courage-bha100
In 2024, national production cards kayin, shan ling, xindu, leippi and ebasso used electronic pipe portable products similar to this front-stage electrode+rear transistor. The only difference is that each has its own design thinking on the electronic tube selection。
For example, the first paragraph of the cap is a combination of decoded xd05t, which uses a small set of antique-grade straight-heat triode tubes in a wider space and power supply。
This direct thermal tripolar tube, by means of its electronic launch, enables it to give the sound a unique sense of warmth and alcohol thickness. This characteristic makes the medium- and low-frequency parts of music more full, and the voices of humans and instruments sound more full, emotional and natural。
On the other hand, direct-heat mini-quine tubes such as jan6418, which work at 1. 25v low voltage, are limited on a more portable side-by-side scene with caine, mountain spirit and ibaso. The direct-heat quintoric tubes, on the other hand, have a certain advantage in high-frequency response, making the high-frequency components of sound more visible and accessible. When music with high-frequency instruments is played, such as the high-sounding areas of the piano, the sound of the violin, etc., the straight-heat quintoric tubes can make the high-frequency sound clearer and more subtle, display a wealth of detail and light, and make the level of music more visible。
So now these hybrid amplifiers, combining the advantages of a galler and a stoner, simplify the design of a galler high-voltage power source, have the advantages of a combination of electro- and transistor circuits, and are more user-friendly, making it possible, with the support of technological innovation, to codify the galler and lighten the entry experience products。
If there are friends who want to experience the machine, then let's not miss it. It will open at the hong kong dragon's dreams hotel, where friends from around jiangyang will be able to travel to the field to feel the difference between a galler and a stoner, to experience first-hand what is called a “bourbon” in the old burner, and to experience other hifi devices。
Of course, in the case of traditional galleries, the fact that they have not been eliminated so far is the result of a combination of factors. In particular, the sound effects of their rich occasional waves, warm and thick, have always been irreplaceable. Despite competition for modern technologies, such as transistors and integrated circuits, the "boldness" of electronic tubes still fascinated many music lovers。
