QB-4 is a setting base that processed the Africa ebony material to 43mm corner. Moreover, QB-5 is a base that processed Asada cherry blossoms to the rectangular lumber of 43mm similarly. It is a valuable article that uses both good quality woods in the state of purity.

The Africa ebony material is a very hard, exact, beautiful material actually used for the oboe and the clarinet, etc.About 1.4, and the specific gravity is heavy, and is one of the hardest, strong materials in wood. The goodness of the sound is evaluated high as a material of our setting base besides acknowledged, and being adopted for a lot of musical instruments as for the Africa ebony, and QB-3 of 34mm corner putting it on the market so far is best-selling in our company. QB? from former It was not possible to commercialize it from the obtaining difficulty of the material though the demand of wanting bases that were larger a little more than three was increased. However, because quite a lot of good quality materials had arrived at last this time, this QB-4 was able to be commercialized. It becomes difficult to vibrate because the larger the material used for the setting base is, the larger mass is, and the effect of the vibration control is excellent. This QB-4 is especially effective when paving it under the amplifier and the CD player.

On the other hand, QB-5 is wood of good quality cherry blossoms system from Hokkaido that our company adopts for the speaker and the wood horn, and the material that our company judged that it is a beautiful material of the sound most in a lot of wood materials for the speaker through a lot of auditions. In the specific gravity, it is a feature that the grain is about 0.73 and a little heavy, is exact, is beautiful, and the sound is also beautiful. A considerable tone quality improvement can expect this of here hitting it off well for the speaker system in 3?4 place [shi] [kukoto].

The volume and weight are almost twices in 43mm corner in this QB-4 and QB-5 though QB-1 putting it on the market from our company, QB-2, and QB-3 are the sizes of all 34 the mm corner. I recommend it to a person not satisfactory by all means with past QB-1, QB-2, and QB-3.

When using it, QB-4 and QB-5 are different the sound depending on the grained direction. Please change grained direction, adjust for the sound to improve most, and use it in the setting.


Yamamoto Sound Craft at a glance

The Yamamoto Soundcraft Corporation is the HiFi branch of a Japanese machinery company. The large technical possibilities the mother company has, together with Mr. Yamamoto's deep knowledge about materials, and about electronics design has resulted in this wonderful and unique line of products. The special situation here is, that the Yamamoto Soundcraft company does not have to use mechanical parts from other companies. Whatever they need, they make it themself, just the way they want it. Resulting from this is the prestine quality level of the used components.

Until 2003, the company was mainly active in Japan only. With the coming of the internet, and growing interest in tube amplifiers, international sales just "happened" to the Yamamoto company. Until then, the company was mainly known in the Japanese-only tube scene. (which is a scene for itself !) But...the internet changed the way of working. There a lot of awards and articles on Yamamoto products.

Mr. Yamamoto always presented the Audio scene surprizingly beautifull and well-designed HiFi Equipment, made of finest base materials.
The accessories Mr. Yamamoto designs are genious products, and improve the performance of existing equipment. They are built built to exceptionally high standards: "Handcrafted" as a tag rarely ever signifies this level of bespoke luxury.

Yamamoto Sound Craft makes phono cartridges, head shells for those cartridges, a step up transformer; a phono equalizer amplifier plus a whole lot more. As you can tell Yamamoto-San is a true believer in the joys of vinyl. One of the most demanded Yamamoto accessories is the headshell made from the african ebony wood of the specific gravity 1.4, it is also used for clarinet, oboe, etc. In wood, a clear and forcible sound is the feature because of a very hard and tough material.

--- Shigeki Yamamoto ---
Here, Mr. Yamamoto demonstrates a test record player for the Japanese magazine "Analog". Please don't ask.... it is not for sale. This was only a study, showing the excellent sonic capabilities of the special treated hard wood as used for all products.
This specially treated cherry wood is called Shashi, and has properties like Ebony wood. So it is the secret tip for Audio products, and of course the #1 choice for the HiFi equipment made by Yamamoto Soundcraft.

Shigeki Yamamoto's professional background includes experience as a high-tech machinist—some of the best and most expensive amplifiers on the planet use his precision-made Teflon tube sockets—and his product gallery is itself a portrait of an audio craftsman with greater-than-average determination: When Yamamoto has an idea for a new kind of capacitor housing—or horn, or moving-coil phono cartridge, or equipment stand, or whatever—he simply gets to work and makes the thing himself. That sort of talent seems out of place in a corporation, or in a field of endeavor that misguided souls have allowed to be dominated by a corporate mentality.

Mr. Yamamoto's music preference is jazz recordings, and he is a very critical listener. His personal experience is, only the finest, natural materials can be used to reproduce the sound in the original way, as it was recorded. For this, no weak elements can be tolerated in the entire sound chain. Only in this way, a true reproduction of the original music will be made possible, with finest details occurring that can not be heard otherwise. This search for originality and perfect materials implicates not only the use of tubes.
It means every part of the product is subject to a careful selection process. Also the use of hard wood and other natural materials plays an important role in the complete design.

--- The Choice of materials ---
The Japanese Audiophile scene uses only original materials of highest quality and originality, going allways back to the root of the products. There is no interest in new inventions, but allways the search for originality comes first. Japanese tube enthusiasts like to improve products, but never loose the philosophy of the original design. This is how they are. You will find this quality attitude in all traditional Japanese companies like Yamamoto Soundcraft is one. They have a word for this, called Kai-Zen. It means so much as great dreams, small steps.
