When I was in elementary school, I had my first tape recorder. It was brought by my relatives from the United States, Sanyang brand and foreign things. At that time, no one in the village didn’t have this thing, just my family had it, listening to radio, listening to storytelling

1. The sound in memory


The understanding of audio comes from a phonograph in my old man's house when I was a child. Although the brand does not remember it, the sound that can be made by putting sing needle on a thin record left a deep impression on me. I hummed with it and it was a pleasure. At that time, I didn't understand what the audio was, but I just thought it sounded nice, but that feeling has affected me to this day.

2. Those foreign things

When I was in elementary school, I had my first inclusion machine. It was brought by my relatives from the United States. Sanyang brand, foreign things. At that time, no one in the village didn’t have this thing, just my family had it, listen to the radio, listen to the storytelling , and there were tapes that my brothers and sisters didn’t know where to make! Since then, I have felt the charm of electronic products and started to fall in love with audio.

3. Start DIY audio


When I was in junior high school, electronic originals and semi-finished audio products were sold on the market. My first DIY speaker. I went to the market to buy a mechanical recorder card holder (a movement), bought an integrated amplifier circuit board for the car disassembled machine, a 4-inch carton speaker, and started assembling the audio. Fixing the movement and circuit board to a piece of wood is bare metal. At that time, I didn’t understand electronic technology, so I just followed the method of handling the items as the master who sold the pieces said. Try countless times. Finally, I heard the speaker of the "speaker" I assembled. That was so excited at that time. It's simply indescribable. I remember that at that time, the amplifier had less than 5W of power, so I connected it with a 4-inch speaker to listen, but the sound was not loud. Later I thought of using a carton to open a hole, secretly hollowed out the quilt at home, stuffed the carton with cotton, and used it as a speaker. The sound released in this way can finally be heard by neighbors.

. Whether it is foreign gun or local cannon

Later, I graduated from college in 1990. What the magic tricks learned was not the radio major that they were interested in, but the electromechanical major. Production of motors, transformers, generators, fans and other products in working units. My first real audio machine was a Marantz merger (probably produced in the 1970s) model was 2500, which was a second-hand parallel cargo brought back from Hong Kong by the shipman (with pictures). Very large size. With a weight of more than 30 KG, the transformer is already filled with marine-grade stretched iron shell seal and epoxy resin. The rectified voltage is 70V high-voltage power supply circuit, and the subsequent high current output is output. The wave capacitor is two 6800 micromethods with 100V. The rear stage is three pairs of gold seal high-power tubes per channel. It has complete protection against high temperature, overcurrent and other factors. The signal-to-noise ratio was very high. At that time, the sound quality was really moving. The sound field is high, medium and low frequency, and the mellowness of the sound is much better than many domestic so-called HIFI machines now. I still keep it as a collection.

. The first time HIFI

. Life has gradually improved, and my mind has gradually become alive, and there are more audio stores on the streets. Listening to the story of Teresa Teng , I decided to have my own system and walk around the streets. At that time, I had too much experience and had nothing to refer to. I could only recommend one set of my own voice, so I had my first set of HIFI combinations, Tianlong's CD 2560; the amplifier is NAD 302, and the speaker is LS3/5a small bookshelf. The sound of this system was like the sound of nature to me at that time, with a soft, warm and beautiful sound! Buy discs, all kinds. I really like it. At that time, I would listen whenever I had the chance, and I wouldn’t feel bored no matter how I listened! If you want to say that time can really change everything, I don’t know when it started. I heard that this system is not so good. I think it may be a problem with the sound source, so I replaced the gentleman Apollo CD, but the effect is still not good. Complete despair, maybe it's because the power of habit is too strong, maybe it's because my taste has become heavier, and I began to like the kind of powerful and thicker sound.At this time, I realized that maybe I should upgrade the entire system.

6. The upgrade is in progress

Now I understand that once I have the idea of ​​upgrading to play HIFI, it is really a torture. My configuration is getting higher and higher and more expensive. I have always seen the Danna C2 platinum version, paired with the Big Pineapple 300, and the audio source decoder is all down and heading straight for more than 200,000 yuan. It is completely beyond my tolerance range. No matter how good the sound is, it will be unlucky to be relieved! You have to pour cold water on yourself, otherwise you will really "break up" if this continues!
wouldn’t it be said that HIFI ruined a lifetime!

just looked back and stuck in his budget, absolutely not exceeding 50,000. Just online comparison and consultation, which started a long road to box selection. Finally, among Baohua 702S2, Stalin and Symphony 2, Symphony 2 were selected. In fact, it is quite risky to make this choice (but online shopping itself is a risky process, and only if there is risk, there will be receipts). The reason why
chose Symphony 2 was because he was attracted by his design and the concept of coaxial plus multiple frequency division. Tianlang had tried this before, but it seemed that the splash was very small, but it shone brightly on Symphony 2 and was very recognized by enthusiasts. Moreover, compared with the Baohua 702, the size and technology of Symphony 2 are very advantageous. Even if I recognize the Baohua brand, in the actual comparison process, the cost-effectiveness still has the upper hand. The second one is less than 30,000 yuan, and the Baohua 702 costs more than 40,000 yuan, and the gap is still a bit big. So Symphony 2 was selected.

sound source The gentleman of the family Apollo CD player can still be used, but the previous amplifier cannot be used. In order to make Symphony 2 have a better effect, I chose the Meredi PRO88 MKII tube. This tube pre-amplification uses Xidian high-resolution WE407 corner tube, the "wrinkle glass" XF184 tube with voltage amplification, phase separation and pushing level is the British shield, and the power is KT88 tube. The output power is 50 watts.

I have also thought about this combination. The characteristics of the Symphony 2 box are good positioning and layering, relatively solid low frequency, loose and natural sound, warm and fresh. The Maledi PRO88 MKII has sufficient thrust and very good resolution, meticulous, soft and soft. The overall style is very compatible with Symphony 2. Although the Symphony 2 box is large and heavy, it is only 150 kilograms per unit, but it is not difficult to push. This 50W power is enough.

After the system arrived home, I also asked my friends to come and help me to set up a position for the staff. I am really showing off, haha! My friend was also shocked when he saw the speaker. It was too big. He was nearly one person tall, with thick upper and lower sides, and his muscles were particularly strong! Of course, it is one aspect of being big. As for whether the effect is good or not, it still needs to be tested. After all, my friend and I finally adjusted the position of Symphony 2 and started to test the sound after the connection was made.
7. Turn on the audition

Let’s first have a passionate paragraph of " Beijing Good News to Bianzhai ". Its melody is very exciting, and it should be said that it is calm and the climax is bursting brightly and vigorously. Rossini's String Sonata by Philips Records has a thick and sticky texture that easily makes people surrender. The 12-inch coaxial unit of Symphony No. 2 is driven by the Melody Gas Machine, and the rich and lingering atmosphere is extremely contagious, while the bass is full and round and elastic. The rich resonance of the cello plays, and the air trembling that covers the entire space is indeed a bit scent.

Symphony No. 2 box looks a little quaint, while maintaining modern audio elements. I think its greatest charm lies in its string music and vocals. Not only does the low-frequency performance make people satisfied, but the mid-frequency performance also surprise me. Xue Wei's "Salute of Love" and Qin Liwei's "Swan" from Longyuan Records, violin and cello are intimate and lovely, full and heavy.When the untight melody slides easily, the strings of the violin are smooth, the tension and elasticity of the cello are prominent, and the tight texture is everywhere, the strong and thick tone is steady and solid, and the warm high frequency adds a bit of sweetness. It is presented leisurely and freely like a stream of water. Symphony No. 2 fully displays the beauty of strings. Strictly speaking, the tone of Symphony 2 is not very gorgeous, and the sound quality is not very slender. It will not immediately be stunning when you first hear it. However, due to the consistent plumpness and plumpness from head to toe, the shapes of the instrument and the vocals are convex and the image is very three-dimensional, which makes people feel very impressive.

The voice part is still full. I said that the medium frequency of Symphony 2 is wide and plump, which does not mean that it will be so thick that it cannot be melted. Its medium frequency is clear and transparent without losing its charm, full of modernity. Yao Yingge The low and magnetic voice on some antique equipment will turn into bass , while Symphony 2 is smooth and clear, breathing and sighing without any compression, like a light-pinked mature woman, in any situation, people feel the beauty of her matureness.

I think if I really bought equipment worth more than 200,000 yuan, I might have a more surprise. Maybe the experience is just like now, which is hard to say, but I think if you have a fever, you must do what you can and don’t follow the crowd. The best thing suits you is. Merchants are not only doing business, but all advertising methods serve their own products and interests. You need to learn to analyze the attractive tinies in advertisements by yourself. Sometimes the greater the hope, the greater the disappointment. Choose products according to your preferences, personality, cultivation, and conditions. Every time you follow the trend, but no matter how you pursue it, you are always being frustrated by the trend, the ever-changing technology and the commercial advertising methods tempted by merchants. Fever always makes people fall deeper and deeper, unable to extricate themselves, and is a vicious cycle. The expensive one is not necessarily the best, the one that suits you is your ideal. Well, I won’t talk so much. I hope everyone can choose the right equipment for themselves. I will continue to tinker with my Symphony 2.
