The 7581amplifier offers dynamic reproduction, leading you to great excitement.

We ourseves were much impressed with the production that the amplifier provided.
And everybody seems to have been excited to hear this "yoshiba" amplifier.(^_^)

In respect of "compatibility of powerfulness and sweetness in reproduced sound" this amplifier stands second to none.
We should say you will not be able to believe your ears!!!

INCORPORATING NANOTECHNOLOGY INTO TUBE TECHNOLOGY

Tube technology, only with refined circuitry, can not offer ideally good reproduction.

We have an idea that even a small amount of impurities included in a metal

influence its character. That is a nanotechnology.

We have been examining closely how those impurities affect signal transmission

to learn how to adjust and make sound as sweet and powerful as possible.

Incorporating nanotechnology into tube technology, we have refined sound quality revolutionarily.

Hearing is believing.. Now why don't you contact us?


We do not know how we can tell you exactly what sonority this amplifier can provide.
It produces incredibly splendid sound.


The amplifier is excellent in sweetness and powerfulness. It makes you feel as if you were sitting in a studio, a concert hall, wherever a source was recorded.


It will get you more excited, impressed and pleased than any other amplifiers can do.
