Bonjour Olivier et Phil
Il m' était également totalement inconnu il y a encore peu de temps, c' est un échange pour obtenir le Stax
ECP-1 qui m' a permis d' acquérir le CA-Z ..
Ces produits sont très peu connus car la firme Stax est une petite entreprise minuscule, à la production et à la distribution confidentielle..
Pour ceux que cela intéresse, un article sur l' histoire atypique de Stax ..

STAX headphone amplifier to blow heavily to upgrade of the unprecedented standard of point
STAX headphones Filed STAX, hook sound familiarity with the National People's Congress understandthat here's a specialized Japanese company producing electrostatic headphones for electrostatic headphones, and a lot fans just heard too much about its name, rarely met, without possibility go through the sweet looks like its pure and noble. But our surprise will be first however it is not the production of STAX electrostatic headphones started. cheap monster beats by dre pro headphonesSTAX Founded in 1938, would be the founder, Mr. Naotake Hayashi, a single electronic music, arts projects and engineers have the same hobby. We STAX not worry about a history of this 1940s, only know the dimensions and good reputation for STAX first successful major business cooperation in 1952: NHK Broadcast with STAX together upskill a use condenser microphones. The early 1950s, this successful cooperation is not only the STAX get yourself a significant commercial opportunity, but into the improved condenser microphones NHK measurement equipment as standard. Almost together, STAX launched a CP-20 cartridge, and POD-1 RF oscillator / demodulator, the device was 1 agile player tracing pickup system, just 1 gram of acupressure is generally completed accurately the tracing. 1954, STAX introduced CSG-1-type capacitive speaker, this speaker and Dr.Heil capacitive increase in pneumatic (Air Motion Transformer) Speaker through the principle of striking similar. Via the 1950s, STAX's work with R & D, Hayashi President creativity with amazing speakers not alone invented a fabulous, improved pickup arm to make sure needle 20 times long life in addition a successful trial in 1959 thanks to electrostatic headphones prototype. This is the way each world's first electrostatic transducer headphones, STAX it named "earspeaker" the ear in the speaker. In 1960, STAX electrostatic headphones of a first commercial system has finally arrived, the SR-1 electrostatic headphones and SRD-1 drive converter. The roll-out of this method have participated in a few audio show, so individuals were surprised doesn't just his work, but will also because his excellent, elegant sound performance. SR-1 specifications even today seems to be quite excellent: the regularity response of 30Hz-25kHz, Maximum SPL 95dB, diaphragm thickness of 6 microns (a micron = 10-6 m), driven bias of 200V . Investigate SR-1 and SRD-1 for this photos I can't help feeling, had the earth's best audio products within the prototype can also be proven so plain, but generation after generation of tenacious efforts of engineers has changed into a listener is not questioned equipment. All over the 60-generation, Hayashi President seems obsessed with singing the popular head, tonearm design and development. 1963, STAX first pair of stereo phono (CPS-40), tonearm (SA-228) about the market, launched in 1965, UA-3 tonearm, several years later, again in UA-3 inside the base wipe with anti-improved across the launch vibration function UA-3N. But little progress on the electrostatic headphones, 1968, STAX SR-1 launched an alternative solution SR-3, SR-3 SR-1 performance with almost the exact, but very particular with regard to the materials used, with the intention that a lot more SR-1 weight of nearly 1 / 3, it is usually worth mentioning by using the SR-3 matching amplifier: SRA-3S, which is a technique of OTL tube amp, put they are driving SR-3 to determine the voice of nature, balance plus more ! music sense. Mr. Hayashi may go through only electrostatic technology with headphones on is just not fun in 1964, he launched a satisfied-range electrostatic speaker ESS-6A and ESS-3A, this extremely expensive speakers was considered the optimal speaker system . In 1973, STAX headphones diaphragm thickness into 4 microns, this groundbreaking model is SR-X/MK2. You shouldn't underestimate the progress, discover that even just in 2001, bulk of the moving coil headphones (including Acura) the diaphragm thickness could possibly be 6-10 microns. 1975 is mostly surprise many consumers, the year this holiday season STAX electrostatic headphones finally cheap enough to help make probably the most of bourgeoisie consumers you should buy the attachment site, additional change is, STAX made everyone incorporate a demanding countries security certification, can finally throw open a large international sales channels. Perhaps some friends usually do not quite understand, headphones and furthermore "safety standard" certification? But when you understand the electrostatic headphone transducer way - via a electrostatic field in 230V or 580V above the bed vibrating diaphragm driven vibration - it will be easier to understand what several people to think about the protection through the electrostatic headphones. monster beats by dre pro headphones discountWith STAX career thriving, as all other engineers excited about audio technology, like, Hayashi constantly looking expand his product chain, perhaps he felt who was everything about face the amplifier is just too big general, along with his electrostatic speakers is extremely match. In 1974, STAX introduced a weighing 36kg, 700W of power DC amplifier A DA300. DA300 output per channel 150W, the output than was generally almost ten times, I believe industry was no less surprising extent resolution now visiting a 1000W × 2 using the A amplifier, keep in mind that, surprised sales don't just its superior performance, but you will also including its staggering price. DA300 because many folks complain concerning price unacceptable, STAX within the next 4 to 5 years, has launched an output of only 40W × 2 DA80, mono 50W of DA-50M as well as "cheap" models. In order to the tastes of middle-income consumer. In your late 70's STAX amplifier, electrostatic speakers, electrostatic headphones and singing go hand in hand customers four areas tonearm system. As the DA300 amplifier in such a town for mountain, speakers after all have to improve. 1974 introduced the ECP-1, premiered eight compilation of well-known static box ELS-/8X/8XBB, but I focused on this to 2 meters with 12 sets of batteries for the bias using the screen-type speaker in a Japanese style room the best way to shelter, good STAX has gradually become a major international brand. But this seems to be mainly of your STAX electrostatic headphones completed. In 1977, a revolutionary electrostatic headphones was born, along with is STAXSR-?, This model virtually the prototype dried up successor product, SR-? Breakthrough in three aspects, first, with the 230V bias to 580V, which makes electrostatic headphone diaphragm movement gained greater momentum, thereby greatly increasing the dynamic range, 580V bias of a standard is being listened to; Second SR-? finally right the thickness on the diaphragm 1 micron, with thanks to the materials science, chemical science and processing technology. We are able to that is amazing without these advanced techniques, how you can resolve the thickness of 1 micron strength, balance, rigidity, connect a series of technical problems; Third, SR-? Connection using PC-OCC material, this high-single- crystal copper wires now utilised within essentially the most high-end two STAX headphones. One year later, SR-? Introduced, SR-? And SR-? Two products appear, the historic established STAX headphones during the audio industry special historical status, tends to make perform properly recording studios, record companies, and Hi- Fi audio monitoring equipment and test producers Fan standards. But I retrospect 20 years ago, SR-? Pro frequency response: 8Hz-50kHz, I only 18 years of human emotion, this electro-acoustic conversion contained in the achievements through the last joint large small, to be sure still won't exceed 82 years products. monster turbine speakers headphonesLike a number of the sound engineer, Hayashi within the increase in other products also constantly seeking to what of improvement. The mid-1970s, STAX almost tonearm generally well-known manufacturers also introduced contained in the carbon fiber tonearm, this high strength, light-weight, nor the resonance inside the ideal material to produce STAX UA-CF, UA-90 tonearm's performance significantly improved, and further consolidate the STAX tonearm performance advantages in neuro-scientific broadcasting. 80's STAX company is constantly upgrading its flagship product, products you can the services 2-40, for instance ELS-F83 electrostatic speakers, the diaphragm thickness of only 6 microns, two teams of bias 4300V/3500V optional power 300W. Electrostatic speakers together with other vegetation is different is, STAX electrostatic speakers being used from your whole band electrostatic transducers manner, as opposed to examples of the manufacturers with the us going for conventional low frequency speaker in order to save costs, such as the skimp altogether, as some British manufacturers low-frequency electrostatic mode to make sure pure, towards Our nation around the high pitch. ELS-F83 frequency response of one's minimum can have 35Hz, nevertheless its costs are exceedingly high. Consistent with these superb volume electrostatic speakers, STAX DMA-X1 launch many of these "coffee table" type of single-channel amplifier, the various readers should realize that DMA-X1 unique wheels when you hit it, as it weighs 101kg, 8 ohm load output Class A 300W, 1 ohm output 1530W. 1W output frequency range 0.5Hz-400KHz, uneven degrees ± 0dB. Careful friends may recall exactly the same U.S. power amplifier, including KRELL and Mark Levison products in 5 to 6 years prior to the birth. X1 this amplifier, in today and subsequently length of time is tough to surpass. Headset serves as a masterpiece in males, 85 years SR-?, Since future SR-? Prototype. 90, with Naotake Hayashi's death, STAX business are utilized in Hayashi Jr. (Hayashi's son) the responsibility of. However , the marketplace is merciless, particularly for a dreamer Hayashi, he put far too much effort and budget spent on these perfect 'flagship' on, leaving the business proper severe crisis. monster diddybeats by dreHayashi Jr.'s Took over, wedding ceremony cut-off electrostatic speakers and ultra-high-power DC-A amplifier, but nonetheless aren't able to take care of the company's financial operations, and Hayashi and his awesome father in the flooring buisingess have your own sound too warm and technology persistent, through the management of experts, he fantastic father made an equal mistake. In 1994, STAX headphone amplifier to blow heavily to upgrade of the unprecedented standard of point, this can be the SRM-T2, this power split, with four 6DJ8 and four EL34 triode connected during the output for a DC, the consequence of most headphones users are almost always a dream, but Hayashi Jr. make certain that he achieved, furthermore within the STAX Hayashi family tree into an end. In small private companies, engineers also are leading send out history ended. Although after 1995 is still only monograph STAX electrostatic headphones within a production, today's president Mr.Y.Meguro still take care of the STAX electrostatic headphones in neuro-scientific the principle position. Otherwise the like to find themselves two generations of magnificent colors Hayashi was mottled as being a piece of wallpaper in seclusion, while using flow of the and gone quietly. cheap monster beats by dre studio blue headphones
... car celui-ci s' est révélé 'sombre' avec une perte d' informations, importante dans les hautes fréquences, une capacité dynamique en retrait, sauf dans le registre grave ... et sans problème d' équilibre gauche / droite .. (le problème de mon ami est ailleurs) ...
, bref rien d' engageant
