CÁC DÒNG AMPLIFIER SANSUI

[trathabin]

International v.s. Japanese Domestic Market

It's very interesting to correlate the relationship between the quality of Sansui products and the establishment of international version of its product lines. The last Sansui product lines sold in both domestic and international markets were Professional and Definition Series with the exception of AU-X1 to AU-X1111, and some high-end separates.

The first 07 Series introduced in 1976 in Japan consisted of AU-607 and AU-707. They did not have the highest model AU-907. In the international market, they named those models as AU-517 and AU-717 respectably. If you compare those, you can find that they are identical in build, but carry different names.

In 1979, AU-919 was introduced in the international market. This is identical to the top of the line model, AU-D907, the second generation of the 07 Series, . AU-D907 Series consisted of AU-D607, AU-D707, and AU-D907 itself.

In the same year, Sansui introduced AU-719 in the international market. This was the step up model of AU-717, and was not the step down model of AU-919. It means AU-719 was newer than AU-919, but used older technology.

I believe that this was the beginning of the down trend of Sansui international models. In other words, AU-919 was the last Sansui top model made the international market, of cause, with the exception of AU-X1 to AU-X1111 and high-end separates.

As mentioned elsewhere in this site, all consecutive international top models, such as AU-D11, AU-D11II, AU-G99X, AU-X901, AU-D901, AU-D901X, and AU-911DG, were less powerful and lesser built than domestic top models.

Of cause, the supreme limited editions, such as AU-Alpha907i MOS Limited, AU-Alpha907 Limited, AU-07 Anniversary, have never made the general international market.

Why? There have been some discussion on this issue among Sansui enthusiasts.

The year 1979, the last year Sansui introduced the top of the line model, the exchange rate between U.S. Dollar and the Japanese Yen was about 260Yen to a Dollar. This was about 38% appreciation on Yen for just a few years compared with the traditional 360Yen to a Dollar that was set at the end of WWII (Yen means round in Japanese - one circle is 360 degrees - this was the rumor why Gen. Douglas MacArther decided the exchange rate at 360Yen.)

With this rapid appreciation of Yen value, many Japanese companies had to adjust their cost structure. Sansui must had to face with the same problem since Sansui was heavily depending upon exports for its bottom line. The best way to cut the costs immediately is to eliminate excess employees. I have the credible source told me that Sansui had union problems since the middle of 1970's. This means Sansui could not get rid of excess employees easily. The second best way to cut the cost is to use less expensive parts and shrink the operation. This must be what exactly Sansui did.

Having the brand name that represents the quality, and worsened the quality as quick and as much as Sansui did. This was the worst thing Sansui could do. As mentioned in the another section, Sansui tried to improve the quality in the middle to the end of 1980's; however, it would take a lot of resources to change the tide. The reason Sansui changed the logo in 1987 must be trying to emphasize that new Sansui is not as same as the early 1980's Sansui.

By the end of 1980's, the exchange rate hit somewhere 120Yen to a dollar. This was another 216% increase in costs. The worst trend hit audiophile industry in the middle of 1980 to today as well. The increasing popularity of personal computers. Every house hold has limited budget to spend on electronics. Most yapees went crazy on computers, including myself ....

Internationally, Sansui have never recovered from the bad reputation of early 1980's. Domestically, Sansui kept producing the high-end products with tremendous loss. There was no mass market for high-end audio during 1990's even in Japan. It's believed that personal computers are to be blamed. Most specialized audiophile companies went out business, including Akai and Nakamichi. Sansui was bought out, and it closed the headquarters in Shi-Yokohama in 2001.

Today, Sansui brand still exists as a cheap electronics manufacturer. However, vintage Sansui equipments still keep playing fantastic sounds, and many people are still discovering once how Sansui was the greatest.

Chào Bác,
Em cũng mê SANSUI, Đang xài con AU-Alpha607XR đây!

[trathabin]

HA Ha
Thế ra thông tin của tớ cũng có người ngó nghiêng cơ đấy! Rất mong được làm quen các Cao thủ âm thanh! Mong được mạn đàm dài dài.

[ngtatliem]

You are welcome!

[ngtatliem]

Bác mê ampli SANSUI, hiện Bác đang dùng loa gì??

[trathabin]

Ở phần LOA Em có hỏi các Bác về phối ghép LOA Technics SB8 với SANSUI AU-AL 777 DG còn gì. Đang phối như vậy, Bác Liêm và các Bác khác cho ý kiến đi chứ, E không biết thế có hợp không hả các Bác. Thanh U so much!

[Capricornus]

Do sơ suất tưởng Bác Trathabin mở trùng Topic nên đã tôi đã mất bài starter .

rất mong bạn thông cảm .

Hồi bé nhà tôi cũng có một món đồ của SUNSUI ( hình như là Radio hay Ampli gì đó ) , nhưng sau này lại toàn là SANSUI .

Có người giải thích là do nó là 1 nhưng đổi tên thôi ( đọc nghe giống nhau thôi ) .

[trathabin]

Chào Bác Carpricornus!
No Prolem!
Tôi phải post lại vì bài đầu có đuôi nhưng thiếu ngọn mà, hơn nữa các Bác phải download mất thời gian

Em nghĩ là ổn vì Ampli sansui chơi khá hay với hầu hết các loa Nhật! Riêng Bác khi nghe cảm nhận thế nào về 03 dải âm?

[trathabin]

À, Nếu nghe nhạc Vàng đặc biệt là Thanh Tuyền hay Như Quỳnh - Trường Vũ thì tuyệt nhất là dải trung và cao. Còn nghe Pop rock thì trầm hơi ồn không được sâu và gọn lắm Bác à

[ngtatliem]

À, Nếu nghe nhạc Vàng đặc biệt là Thanh Tuyền hay Như Quỳnh - Trường Vũ thì tuyệt nhất là dải trung và cao. Còn nghe Pop rock thì trầm hơi ồn không được sâu và gọn lắm Bác à

Em nghĩ, thường thì mỗi loại loa thì có mỗi sở trường riêng, có rất ít cặp loa đánh được hay tất cả các thể loại nhạc. Vì lý do đó có rất nhiều người mua vài bộ loa khác nhau để nghe tuỳ loại nhạc mà họ thích!

Hay là tại em nhìn chưa quen nên thấy vậy! Chứ nó là hàng đời cuối cùng của SANSUI trang bị mạch cao cấp nhất, gửi Bác thông số nó đây:

SANSUI AU-α 607NRAII
\ 119,000 (1999 sale)
　
The revised model of AU-α 607NRA.

In order to remove the interference between the power source coils which happen inside trance, it loads onto the final step with left and right independent source system making use of speaker drive private EI core trance, it has become the question detour constitution which frees the power source supply to the final step by loading toroidal trance onto power source of the pre- drive step.
In addition, you adopt the ripple filter circuit for power source in the pre- drive step, from you have become the power source which is stabilized.
Toroidal trance the seal being done completely, the pure copper material, by the [tehuronshito] special rubber in floating state is installed on back of the front panel.

The [sansui] individual Ultimate α-X balance circuit is adopted.
Electric current margin of the driver step is raised in former 2 times and the first level and the driver step, with the transmission expansion process which reaches to output from input of final stage, the hardware requirement which is superior is actualized by being able to point to A class operation.
In addition the balance amplifier is the balance constitution where all stage does not depend on the ground circuit, because it is the push pull system which + of L/R - puts the private amplifier both sides, drives the speaker under the same conditions with the amplifier of total four, like the former gland amplifier through the ground, there are no times when the sound quality is impaired by the ham and the noise component which flow into they remove the mechanism of the strain which originates in speaker drive, have improved the sound quality.

Phase inversion it is not in the pre- drive step with + - loading the NEW diamond differential circuit whose it is possible to remove output, it increases.
Because of this, as the heavy-current which is stabilized with the responsiveness which is superior vis-a-vis the input signal which changes instantaneously, can be supplied, occurrence of TIM distortion factor is held down very low.

NM-LAPT (the [nonmaguneteitsuku] [riniaanpurihuikeshiyon] power transistor) you have adopted for the power device.

Trance and the electrolytic condenser by the center of the chassis, each power unit of L/R the twin monaural construction which left and right symmetrically designs is adopted.
Because of this, the interference of L/R is prevented, the vibration which occurs with electrical power system and vibrating system is controlled from the structural aspect.

Furthermore the NEW α-X balance power source which evolved is adopted by 2 trance power circuits.
The final step left and right independence balance type close and the pre- drive step top and bottom object balance type are designated as electric current power source low, furthermore power source itself of the pre- drive step and final stage is made close droop constitution of the complete independent formation which is separated from trance completely.
Furthermore, the separator and the plain foil were involved in the electrolytic condenser of the final stage private power source section, in addition to the sound quality foil of magnification ratio low, original block capacitor is adopted.

Strengthening twin monaural construction and [aisoretetsudo] mechanical feedback. Mechanical floating system is adopted and, vis-a-vis power transformer.
Trance is installed when it is made flow from the chassis, interference to the sound quality structurally with the vibration of electrical power system is cut off.

In order to hold down occurrence of the vibration of the radiator where the power transistor is installed and resonance, the radiator of new form is adopted.

The special material and the elliptical insulator which adopts structure are adopted.

6 connected D tent volume are adopted to volume.

The polarity indicatory attaching power cord/code is adopted.

Còn nếu Bác khoái chất âm của MOSFET thì có con SANSUI AU-α 607 MOS Limited cũng nghang tầm đó:

SPEC của nó đây:
SANSUI AU-α 607 MOS Limited Limited production item
\ 180,000 (1999 sale)
　
From those which are repair stock of the old type MOS FET where already production has ended, the limited model which uses those which 8 years in manufacturer guarantee period pass, for the amplifying stage.
As 07 series, it is the model which is sold lastly.

In the power step of 607 MOS Limited, because the accumulation effect does not occur it is superior in the linearity, it adopts the old type MOS FET which makes the high-speed expansion which is stabilized possible with pair as the output element.
This element started in AU-X111 1984, AU-X1111 MOS VINTAGE (1988), B-2105 MOS VINTAGE (1996) and the like was loaded onto the high-end model of [sansui].

Largest technical approach was in actualization of optimum hardware requirement for the electric current operational amplifier in 607 MOS Limited.
First, in order to improve the operation of the output step which is many electric current inside the amplifier necessary, new it develops the large size weight class trance which designates the secondary winding electric current of trance as 10A of former approximately 2 times in power transformer, actualizes instantaneous heavy-current supply and increases.
It makes those of 65φ/8200μF×2 which has been adopted for B-2105 MOS VINTAGE in the power source condenser, corresponds to instantaneous heavy-current response. Furthermore, in order to increase the electric current room inside the amplifier the attachment power cord/code, the power switch modification to the electric current room of 15A. Electric current route is made to stabilize, instantaneous heavy-current response is actualized.

Loading the Ultimate α-X balance circuit which is circuitry of the balance amplifier. With the luxurious making which adopts power MOS FET for the output step, also electric current margin of the driver step makes former 2 times, has made A class operation.

In order causes a kind of cross modulation vis-a-vis the music signal, to cut the mechanical vibration from inside and outside the amplifier effectively, in basic structure, the electrolytic condenser and the power source section which consists of mechanical floating power transformer were arranged on the center, strengthening twin monaural construction is adopted, layout inside the acoustic image and phase stabilize is actualized.
In addition, in order for the vibration of power transformer not to be transmitted to the chassis, adopting the pure copper material and the teflon. Furthermore, also control of the vibration by the teflon tape which so far has the result with the high-end machine and the like of [sansui], has adopted for isolation effectively with the principal point.

The radiator of the elliptic form which designates vibration occurrence as minimum is loaded, interference of the signal and the music signal of electrical power system is cancelled from basic structure.
In addition, transparent resin elliptic form type of [sansuiorijinaru] is adopted to the insulator, dispersion and absorption of the vibration are done.

Em đang định múc con này ở JP giá tầm 1000usd, các bác cho em ý kiến nhé

http://bag08pr000.auc.bbt.yahoo.co.jp/u ... 600001.jpg

[caithang]

Con này đã ngon nhưng 1000$ tai JP bác múc được 1111 vintages (4 con 1) còn ngon hơn 111

[convitcon]

Đang có 1 con X111 ở auctions Nhật, chỉ bị lỗi Protection, hiện giá khoảng 20000Y thôi, bác nào thích thỉ thử xem

[tonken]

Các Bác cho em hỏi con SANSUI AU anpha 555VS chất tiếng no ra sao ạ ! em định mua giùm cho một ông bạn với tầm giá 1m6 có được không các Bác

[ToniHoi]

Chào Bác!
555VS là amply trung bình của SANSUI con này sản xuất có bo mạch sử dụng VIDEO. Chạy 2 sò mỗi kênh. Âm thanh mạnh mẽ hơi cứng chủ yếu nghe pop rock. Nhưng nếu mở to có thể bị vỡ tiếng bác nên ghép với loa bass 2t5 trở lên nhất là loa PIONEER.

Thân.

[Zorro]

Con này đã ngon nhưng 1000$ tai JP bác múc được 1111 vintages (4 con 1) còn ngon hơn 111

Về hình thức và ruột bên trong, 2 con X111 và X1111 như nhau, chỉ khác là X1111 sử dụng vài linh kiện (tụ điện) đời mới hơn mà thôi.

Thân.

SANSUI là dòng amly hay, kinh tế và khá cá tính theo cảm nhận của riêng em. Cty SANSUI cũng có một lịch sử từ khá lâu và đã cho ra đời nhiều dòng Amp chất lượng cao và được người tiêu dùng không chỉ ở chính quốc Japan đón nhận. Em đã và đang chơi con amp cỏ 607DR được khá lâu rồi và rất ưng ý về chất âm trong tầm tiền, ngọt ngào, treble, mid và bass đủ.
