Description STAX SR-407 Electrostatic Ear Speakers Condenser Headphones w/box Used Very good[Condition]USED:Very goodoperation confirmedSTAX STAX SR-407 Signature ? type = final version top / sounding body similar to 507 SR-009 transfer / super engineering plastic discontinued = PCOCC / single crystal conductor will be exhibited. In this auction, items in various conditions are exhibited, but this item that I would like to introduce this time is a second-hand product that is in good working condition. Comes with original box/instructions.[SR-407 Signature]The ? (lambda) type, which is Staxs main model, can be said to be the companys icon.It is a product with a unique form, and is the most well-known and has a wide variety of models.Once it went bankrupt, and the fate of the conspicuous electrostatic ear speaker was about to run out.His SR-404 Signature / 303 Classic, which the companys volunteers gathered and newly launched New Stax bet on the companys future and asked the world, sold well, and his name recognition increased. . Ten years later, his long-awaited full model change is his SR-507 / 407 Signature / 307 Classic. This exhibit is a model that corresponds to the second son of his three brothers. This ? type first appeared in 1979 when it was the old normal bias, and the professional bias specification was later introduced in 1982, so it took 36 years until it was renewed as the current L series = Advanced Lambda in 2015. It has become the backbone of Watari Stax and has played a central role. This series = SR-507 / 407 Signature / 307 Classic has become the final model of the traditional lambda type. It should be noted that it has the same sounding unit as the big brother 507 which was pre-released at that time. From the manufacturers point of view, sharing components is a wise decision that will lead to cost savings. The SR-507 adopted a head arc and genuine leather ear pads, which can be said to be a special design, so the cost was higher, whereas this SR-407 uses the same head arc and synthetic leather ear pads as before. We were able to keep the price down by doing this. It is the same sounding unit as the big brother = SR-507, but the output cable is greatly different in that it uses a single crystal conductor = PCOCC, which was developed during the heyday of audio and has now been discontinued. I feel that this output cable plays a big role in having a different charm from the 507. The core sounding unit has been revamped and greatly evolved. We took on the challenge of further increasing the rigidity of the sounding body/vibrating membrane, which is the heart of the instrument, and adopted his super engineering plastics as the material. Surprisingly, the diaphragm of the same material as the flagship = SR-009 at that time is used. By packaging the sound unit with reinforced resin, it became possible to fix it to the ear speaker housing with bolts for the first time (using an adhesive) to achieve even higher rigidity. The tight output cable uses a wide, low-capacity type in which each conductor is spaced apart, and the output cable is now out of print. It is a copper material that unfortunately has been discontinued because it is not profitable. Since Furukawa had registered the trademark PC-OCC for single-crystal oxygen-free high-purity copper wire, the OCC conductor manufactured by the company can be called PC-OCC. The conductor produced by this method has theoretically zero crystal boundaries, which means that there are no elements that interfere with signal transmission. It was a very famous electrical material used by cable manufacturers as their main product. In Japan, it is a production country, so you may have a common impression, but overseas, it is a conductor that has established a very high reputation. The promised (!?) sponge is prone to deterioration, but the inside of the back cavity on the outer side is still in good shape. The inner side is a current mesh screen that does not deteriorate. It is undeniable that he lacked presence because he was the second son, but judging from the contents, I think that he is a considerable ability machine.There are scratches and threads associated with use, but I felt that there was no major damage.
