Enjoy music reproduction perfect taste ------ G & W TW-2006X integrated amplifier Author: Zhu Hao Song
In short, people who are touched by listening to music software with audio equipment generally have the following two situations: First, the listener is familiar with the track being played, and the mood at the time matches the mood of the song, and the listener resonates And moved; another situation is that the music reproduction ability of the audio equipment is very good. Whether the track played is familiar or unfamiliar, the sound played is always beautiful and beautiful, which can accurately reflect the connotation of the music. The listener is attracted by the mood created by the music and is moved. The first kind of situation is touched by the mood. In this situation, whether the listener listens to Hi-Fi audio or tape, or even a high-pitched loudspeaker, as long as he (her) touches his or her heart, it will cause him (her ) Resonance. The second situation is whether the audio equipment has the ability to impress the listener, that is to say whether the equipment can make a harmonious and pleasant sound. It can make a beautiful sound and let the listener enjoy the pleasure of listening. Then, this piece of equipment is a good piece of equipment. To measure by such standards, G & W Tsinghua University's latest model TW-2006X integrated power amplifier is an excellent device.
Speaking of G & W's products from Tsinghua University, you must have heard of them for a long time. The audio products designed and manufactured by it have won a good reputation among enthusiasts. Like the gentle and solid single-ended class A front and rear class, the plump and sweet 660SE field effect tube combined power amplifier and the T2.1 bile headphone amplifier that is known to be the same price as the Sennheiser HD600 are perfect products. A low-cost TW-2008X amplifier with excellent sound effects is a hot topic for enthusiasts.
The model TW-2006X is the latest product designed by Wu Gang. Its design is based on the well-received TW-2008X. It is improved for some shortcomings of TW-2008X sound, the main part of the improvement is in the pre-stage. Generally speaking, in the combined power amplifier, the timbre of the pre-stage is more important than that of the power amplifier, and the pre-stage has the greatest influence on the timbre.
Enthusiasts should know that it is currently impossible to fully regenerate the texture and energy of live performances on audio equipment. Even a note played by a primary school student on the piano and a street performer who pulls on the erhu so casually do not sound the same on audio equipment. Coupled with the distortion in the recording process, the sound characteristics of the recording venue, and the unpredictability of the listening environment in the home of audiophiles, we still need to discuss whether the sound replayed by the audio equipment at home is actually reproduced? Our concern should be whether the audio equipment can produce pleasant, balanced, harmonious and non-aggressive sound. The TW-2006X merger designed and produced by Wu Gang is closer to this aspect.
From the conversation with Wu Gang, I learned that the design concept of this amplifier is this: treat the two speakers as a large headphone, and design this amplifier as a headphone amplifier with a large output power. This is the first time I have heard of such a design idea. In order to confirm this statement, during the audition, I specially found three famous high-fidelity headphones, Sennheiser HD600,580 and AKG K240M, coupled with Wu Gang ’s T2A amp to repeat In contrast, the same pioneer PD-T07A CD player is used as the sound source, and the TW-2006X power amplifier is used with West Lake ’s 6.75 monitor speakers. The sound is like the sound of the T2A gall amp pushing the Sennheiser HD580. It is really full of surprises. . For friends who have the TW-2006X power amplifier, when using it, the speaker can be placed using the "headphone positioning method", which feels really wonderful.
The appearance of the power amplifier designed and manufactured by Mr. Wu Gang is generally unsatisfactory. This may be related to the viewpoint that "speaker equipment is used for listening rather than watching." This amplifier is no exception. The appearance looks unpretentious, unremarkable, and does not make people feel bright. Only the two gray left and right symmetrical volume and signal selection knobs are a little different, plus a chic ring-shaped power switch button, the overall gives a sense of stability and solidity. Other than that, there is nothing worth showing off. What really makes people look at it is its internal craftsmanship and structural layout.
Open the cover, the inner layout is reasonable, the structure is compact, the device is installed dignified and firm, the wiring is orderly, and the production process is pleasing to the eye. The circuit design uses JFET field effect tube differential input, two-pole compensation network, super linear amplifier circuit, and low-distortion three-stage Darlington push-pull amplifier. High-quality imported iron core wound 400W high-quality ring cow, Japanese ruby ​​for power filter, double-sided 70um thick copper foil circuit board, carefully tested and matched eight Toshiba 2SC5200 / 2SA1943 high-power tube output, ALPS blue high-end potentiometer and other fine products The use of components has a basic guarantee for the quality of the whole machine.
This is a transistor machine in the same price range that is closest to the high-quality bile machine. It is even more "smooth" than some ordinary bile machines. Compared with a domestic machine with nearly 4,000 yuan using EL34 bile ducts, The same is the 6.75 speakers of the West Lake. The sound from this amplifier is cold, sharp and rigid, but it is like the sound of the transistor machine that is usually defined. G & W's TW-2006X power amplifier is warm, moist, harmonious, and more like a guts. And after replacing the 6CA7 of the Russian EH with this amplifier, it made another qualitative leap and became comparable to TW-2006X, which was ridiculous, and once again confirmed that "changing the tube is like changing the machine". "The most famous saying".
During playing the TW-2006X amplifier, use it to push too many speakers of different styles in order to test its adaptability. These speakers include West Lake 6.75, JBL's 4312MKII, TAD's 300 Aberdeen, Le Jazz's 15 Euro version LS3 / 5a, He Hua Audio's Oishi 1.0, ATC's SCM7 and so on. With these pairs of speakers, the sound shown, except for the thickness of Le Jazz ’s LS3 / 5a is not enough (this may be related to sensitivity, impedance matching, and unit caliber) and the 1.0 strength of the Tweezer is slightly weaker (the famous and difficult 8545 wrinkle Basin, but full of charm, and the thrust is much better than that of a 300B tube amplifier with two tubes in parallel. It is said that his weaker strength is for this pair of boxes). In addition, it has a good effect with several other pairs of boxes. Especially with the West Lake's 6.75 bookshelf box, it turned out to be a perfect match. Coupled with the pioneer's professional CD player PD-T07A as a sound source, don't underestimate this CD player that was launched in the early 1990s. It actually compared a domestically-made CD player that has been frowned on for more than 10,000 yuan. ,Unbelievable. This inverted CD turntable can be regarded as one of the best turntables in the world. I wonder why Pioneer doesn't produce such turntables now? Most of the comments I wrote this article also come from such a system, and the longest listening time.
At first glance, this amplifier will not give people a bright impression. However, as long as you listen quietly, you will slowly be "corroded" by the notes it emits and blend into its sound and forget its existence. He made you focus on the development of music rather than the characteristics of sound. And the longer you listen, the deeper your experience. This is what makes it extraordinary, and its biggest feature. The feeling of balance, harmony, comfort and pleasure is indescribable, just like the warm feeling of people bathing in the spring breeze in March. The soft touch, especially the stringy touch of the string music, makes people feel both physically and mentally relaxed, lying lazy on the sofa and not wanting to move. I really have the feeling of listening to a high-quality amplifier, but it is better than my 300B amplifier in terms of speed, transients and dynamics. This is especially obvious when playing the cello software. It is also the 6.75 speaker that drives West Lake. The cello played by TW-2006X looks more substantial and full, and the 300B low-frequency feeling always seems to lack some condensed silhouette, It's just a little bit tickling.
Balanced is good, because music is balanced. Audiophiles who often listen to the introduction often say how beautiful a high-frequency device is, how low-frequency it is to the meat, etc. when evaluating a device. This kind of evaluation is wrong. A piece (set) of equipment is meaningless if it does not consider the overall sense of balance and only evaluates certain local performances. This is also the easiest mistake some motorcycle enthusiasts make when they modify some of the world's mobile phones, "getting a certain improvement and complacent and not knowing that it has destroyed the overall balance of the aircraft." The biggest change of TW-2006X and its predecessor TW-2008X is that the charm of the sound is more perfect, it looks more harmonious, more natural, more balanced and listening. Just try not to provoke the less sensitive (83db) speakers when pairing.
During the audition, I accidentally met with a 12,000 yuan YBA No. 1 merger, "the two armies met the brave and won." At that time, the sound source was Marantz ’s 14SACD machine, and the LS3 / 5a 15 Euro version speakers of the push Jazz took turns. The TW-2006X amplifier was actually better than the YBA No. 1 machine in sound texture, thickness, charm, and sound field expansion Outperform. The owner was dissatisfied and replaced with 300 TAD, the result was still the same. A senior enthusiast who was present at the "watching the battle" said the following after listening to the voice: "At this price (the retail price of the aircraft is 2880 yuan), its voice performance is invincible. Many power amplifiers in the market have to die 'In its hands. "I wonder if this is the case? I just realized from this amplifier that the real purpose of playing audio is to enjoy music!
