Comment on AΣLegendsound Legendary Fantasy Fantasy Mono Back Level Amplifier

Canada's AΣLegendsound legendary voice has not entered the Chinese market for a long time, but several CD turntables, decoding and all-in-one players have won the market recognition with excellent quality. For example, the combination of the CD4 turntable and the Fantasy fantasy decoder is on the list of the 2011 new audio equipment list. The CD12T has also been unanimously praised by the editorial team and the commentator team. It has become the trend of digital streaming in recent years, and the CD player field is going upstream. A new force AΣLegendsound's product design philosophy focuses on reasonable circuit architecture, selection of high-quality components and a sound sound adjustment concept, and strives to discover the maximum potential of the CD. There is no plausible concept hype, and there is no illusion. New technology", "new noun". Therefore, the work materials are solid, the sound is lively, delicate, and resistant to listening, which has become an important factor in people's choice of AΣLegendsound.

Perhaps because of the obsessive requirements for sound performance, AΣLegendsound's new product development cycle is very long, remember that the last time listening to CD12T is almost two years ago. AΣLegendsound's domestic agent and I said that the factory actually has a series of product development plans, but after designing the prototype, it will take a long time to repeatedly compare and listen, even if it is a small adjustment of resistors and capacitors, it will go through a long time. Listen to the market until the sound is perfectly satisfied. This process is absolutely extravagant in terms of the modern business philosophy of stressing everything and time is money. However, it is the factory's persistence in the aesthetics of sound aesthetics that is the foothold of AΣLegendsound in the strong Hi-Fi audio market. This is not, this time listening to this set of Fantasy fantasy mono-level power amplifier is a masterpiece of the factory development for a long time.

Heavy chassis design

The agent sent two heavy packagings, and the editorial staff took care of the boxes and was afraid to flash. The two mono-level rear-end design is not fancy, but it is very solid! Although the factory specifications do not give real specifications, but conservatively estimated that one is also about 25-30 kg, so the factory designed two large hands on the back panel to facilitate the use of equipment. Fantasy's fantasy mono rear panel is simple in design. In addition to the power switch and power indicator, the design elements are a small groove of precision machine tool milling. Although simple, it can't be simple, but delicate brushing and blackening treatment. It is the best embodiment of fine craftsmanship. The source of Fantasy's monophonic mono-level weight is firstly a solid all-aluminum chassis, a thick chassis, side panels and other chassis walls to build a solid chassis, not only can offset the physical resonance to the greatest extent, but also play The function of shielding electromagnetic interference makes the signal amplifying circuit work in the most stable and pure environment.

From the structure, AΣ Legendsound uses a built-in heat sink design, which is not as human-like as many high-power amplifier products. Exposed radiators, if the heat dissipation efficiency is higher, will inevitably affect the appearance coordination, and it is also difficult to clean and easy to scratch. In fact, the Fantasy phantom mono amplifier uses the entire heavy-duty chassis to dissipate heat in addition to the built-in heat sink, so there is no need to worry about stability when working for a long time.

靓Power is the basis of good sound

Legendary Sound Fantasy Fantasy Mono Amplifier RMS Continuous effective undistorted power of 200W (8Ω), dynamic power of 600W, the factory claims to be able to easily control most of the low-sensitivity speakers on the market, showing confidence. For the power amplifier, or for the audio equipment that needs to be plugged in, whether the power supply circuit design of each product is in place directly affects the sound performance, and it is also the relationship between the driving force and the control power of the power amplifier. AΣLegendsound has always emphasized the importance of power supply design. From the CD4 turntable, it can be seen from the use of three Noratel hedgehog toroidal transformers. AΣ Legendsound has extremely high requirements on the quality of the power supply. The factory engineer believes that the audio equipment works without electricity. If the power supply quality is not good, it will inevitably lead to unstable circuit operation, and the buzz will not be discussed. Therefore, the design of any audio product should be in the first place. There are many means of power supply. For example, many products now use switching power supplies. In theory, the power supply efficiency and response speed are good, but the high-frequency interference generated by the switching power supply is extremely difficult to avoid, thus seriously affecting the sound performance. In comparison, AΣ Legendsound believes that only the traditional transformer power supply is the right way, but in fact, most of the transformers that can be bought in the market are of uneven quality, and the poor quality transformer itself will generate a lot of vibration and heat, and The magnetic leakage phenomenon is also very serious. It is conceivable that such a transformer used in an audio product may seriously affect the sound performance, such as high frequency burrs, medium frequency or thin or turbid, low frequency lines and the like.

The transformers used by AΣ Legendsound are all Norwegian Noratel porcupines, which are the highest standards in the industry. They are tailor-made according to the design requirements of the circuit. The well-known enthusiasts know that many Hi-End equipments sold at high prices use Noratel transformers. of. This Fantasy fantasy mono amplifier is no exception. In order to ensure the sound is fully dynamic and the sound details are restored, the power transformer adopts the EI transformer of the European brand “Dragon Pig”. The senior Hi-Fi enthusiasts will have the power transformer of the same power amplifier. The power size and type (ring type and EI type) have a great influence on the sound. The ring transformer sound is relatively refreshing. The sound performance of the El type transformer is more balanced in three stages. This is the test of the legendary voice designer. As a result, the transformer's appearance is different from the conventional square EI transformer, the conventional one is square, but the Fantasy fantasy mono amplifier is rectangular, it is understood that the original legendary sound engineer and the European transformer manufacturer engineer passed More than a year of research is especially designed for this amplifier!

In addition, the power filter section uses 8 UK Nover 18000μf electrolytic capacitors, which are connected in parallel to a total capacity of 144000μF, so that the power system has low internal resistance and excellent performance in large dynamics. Nover Novartis Capacitor, a veteran British manufacturer with decades of experience in producing acoustic fever capacitors, has always been the target of choice for top audio brands and the most dedicated DIY enthusiasts. This kind of capacitor is famous for its elegant and mellow tone. Some people have compared the capacitor products of several brands horizontally and said: "Nover Novartis Capacitor is a welding machine. The sound heard is quite transparent, much better than the transparency of Japanese rubies. The sound is quite watery, the low frequency dive is powerful, and the water is the best adjective. No wonder many people say that if you want to play, you can play the British sound."

High voltage working circuit

The power supply system of Fantasy Fantasy Mono Amplifier is spectacular enough. What about the circuit architecture and materials? In terms of motherboard parts, all of the crystal transistors produced for audio are used, which can achieve excellent levels of sound in all aspects. In the picture, you can see the circuit board installed horizontally. The radiator is equipped with 6 Toshiba's latest high-power transistors developed for high-end fever audio for power amplification. 6 transistors are paired by Toshiba original factory, and AΣLegendsound is also rigorous before storage. After the test, the equipment is ready to be loaded, and the error is minimized to ensure that the sound is naturally smooth and true. 6 power tube amplifiers can push most of the low-sensitivity boxes on the market. This is a bit confusing. In fact, the principle is very simple. It is proportional to the voltage and current according to Ohm's law. As long as the power supply voltage is increased, the current (power) Just improve. Originally, the DC power supply of the power tube of this machine has a positive and negative voltage of 130V. Experienced designers will understand that when the power tube is connected in parallel, the error of each power tube will seriously affect the sound performance and cause the sound to become "thick", but why Are there many entry-level amplifiers that use more than a dozen tubes in parallel? The reason is the pressure resistance of the parts and the cost of the parts. Since the supply voltage is a problem of the system architecture, the machine of the high-voltage power supply system requires high withstand voltage for each part, and the purchase price of parts with high withstand voltage is very high. Therefore, the advantages of multi-tube parallel connection of low-voltage power supply are lower cost and sound performance is not as good as high-voltage power supply. The advantages of the high-voltage power supply system are fine sound, good low-frequency control, and wide sound field. The disadvantage is that the cost of the whole machine parts is high. The designer skillfully uses the influence of the inner leads on the sound, as well as the electrical characteristics of the line structure to the parts and the power supply efficiency. Pay attention to the details of the line and find that all the wires of the cable are made of "cold crimping terminal". All the wires in the original machine are oxygen-free copper wires produced and ordered in the UK, but the temperature is high. The welded copper wire immediately turns into copper oxide, and this line becomes useless when it becomes a common copper wire.

Both strength and beauty

One week before the official audition, I found some speakers to pair with the Fantasy fantasy mono amplifier. Among them, the Sonus Faber Olympica II floor-standing box that I have been listening to recently, the former is Audio Note Parts. M7, the sound source has the magnetic LM-515CD turntable + Luxman DA-06 decoder. In this combination, the whole system shows excellent stability. Even when playing at a large volume, the sound image still has enough weight, and the image is clear and stable (each sound image will not swing or rush forward). Even the performance of the orchestra, the position of the various departments and the front and rear levels are still in order, and will not be confused. These characteristics are not like the use of "only" 200W rear-end drive speakers. I have heard some output before and after 300W. There are not many models that can achieve this level. The Fantasy Fantasy Mono Amplifier has a unique temperament. When it plays music, it seems to be quiet all around, and the listener's mood is calm, unless it is listening to rock music, jazz live recording or symphony. Besides, I almost didn't even want to turn the volume up. When the mid-low volume is played, the instrument's strong and weak sounds still show a clear difference.

Fantasy Fantasy Mono Amplifier has a high sound resolution, but it is by no means a slim type. Its high resolution can be said to be "recessive": it does not deliberately emphasize high frequency, and the overall tone tends to be warm, it can bring the viola with The sound of the violin is clearly divided (the listener does not have to deliberately distinguish), even if it is also a violin, each piano's own unique tone personality can be fully and delicately presented. Compared with the high resolution of professional audio-visual equipment, this system also has the same amount of intelligence, but there is no tension in the sound personality, and the sound is easy and natural.

Superior control

Originally, I was listening to such a medium-sized combination. I didn’t expect to reproduce Beethoven’s Ninth Symphony and Holst’s Planetary Suite, which was the test of control and driving force. Fantasy monophonic amplifiers can handle a lot of symphony works in the case of addiction, and the dynamic fluctuations far exceed my expectations for this combination. The Sonus Faber Olympica Opera II floor-standing box is barely medium-sized, but with the Fantasy fantasy mono amplifier, even if the RR's organ recording is replayed, the low-frequency energy is saturated and flat to the very low frequency range. Fantasy's fantasy mono amp is still stable, and the organ makes the music solemn. The delicateness and space of other instruments are not degraded by the high output of the low frequency. The momentum.

to sum up

Usually, the software I use when I listen to the equipment is roughly one-third of popular, jazz, and classical music. I listened to the Fantasy fantasy mono amplifier, but I did not consciously listen to a lot of classical music, especially RR, DG. Those records that are usually not daring to broadcast, or that are often not well broadcasted, are very nice at this time. Fantasy Fantasy Mono Amplifier has a unique charm, which can bring the complexity and subtle changes of classical music to a complete and complete presentation. It also keeps the classical music vivid and charming. Many familiar softwares seem to be at this audition. Re-understand the general. The performance of Fantasy's fantasy mono amplifier has far exceeded my previous impression of transistor amplifiers. The mellow tone is not even cheaper than many amplifiers. As for other Hi-End amplifier brands, the sound quality is If you want to surpass Fantasy's fantasy mono amplifier, you may have to spend more than a budget and have enough experience and luck. Based on the performance and price of Fantasy's fantasy mono amplifier, I think it has exceeded the level of “value for money” and there is no reason not to recommend it to you. The advantages of high-power amplifiers are more stable. When they are bursting, they are calm and unrestrained, and the sound field will not collapse. The sound quality is less prone to sound. Because of the arrival of the big climax and the sudden strong sound, it will consume a lot of current. The benefits of using high-power amplifiers for a thousand days are even more obvious.
