We are always making efforts to discover necessities for ga new
Electro Sound Fieldh (the aim: to arouse deep impression in onefs
inside). Up to now, they are gHigh Qh and gfaithful reproduction of
precise wave formh. In order to implement by hardware, we are always
finding components of good identity in used apparatus and we are making
a new apparatus utilizing them on the base of gthe best tone-qualityh.
We
have confidence to be sure of the sound quality because the apparatus
is a remake of severely selected used ones. Changes of ICs, components,
remaking of chassis and remaking of power supply part are important;
precise adjustment of position of power transformer, precise balance of
rectifying diode bridge and rectifying electrolytic capacitors.
These effort concludes reproduction of n*, n** and functional beauty with careful setting of apparatuses.
(as to n*, n**; see the foot note of Top)
Details
of manufacturing are: point supports of chassis about 0.1mm precision,
changing to good components, cutting of circuit board and adjusting
supports. Control of unexpected vibration will never be compromised by
a method of ggum suppressionh. The sound of warm and strong, low
gravity is obtained by careful selection of electrolytic capacitors and
film capacitors.
Digital distortions are suppressed by the
revolutionary idea of Patent p096010 which decreases both time jitters
and amplitude errors.
Concerning the speaker box, gHigh Qh
requirements are realized by adamant brazen ports, point support, and
varnished inside with carefully adjusted small quantities of acoustic
absorbent materials. Wave front is carefully adjusted, and these idea
and efforts bring about the sound of n*, n** (as to n*, n**, see the
foot note of TOP).
Almost of all apparatus are evaluated as ggood functional beautyh.

Newly designed dual concentric single corn speaker with Hawley corn diaphragm and electromagnet. From the basic research of ga new Electro Sound Fieldh, it is clarified that the faithful reproduction of wave form of an input signal especially the faithful reproduction of transient parts is indispensable. Performance of the reproduction of transient parts by electromagnet is splendid.
The sounds atmosphere is just like old movie theaterfs one. It will be greatly enchanted.
