You could not taste before

Step up the signal from the MC cartridge without loosing any signal

Description
The transformer is Hashimoto trans.Its sound quality is delicate and dynamic, beautiful, clear, from low to high, it reproduces sound clearly without leaving. It is the MC cartridge step-up transformer of the highest grade product that provides music reproduction that you could not taste so far.
In order to send a signal to the amplifier, selection of winding structure including high mu PC core, setting of physical structure, strictly triple shield, Using Hashimoto 's input transformer for MC cartridge which was designed to dispersion of vibration mode etc., ASTOR made high performance MC cartridge step - up transformer. ASTOR made products by using high quality materials and parts pursuing for the best sound quality.

For the MC-999NS&MC-999US series transformer chassis, use oxygen-free copper panels of 2 mm thickness and 5 mm thickness, by laminating the inside with the anti-vibration material, the vibration which adversely affects the sound quality is eliminated. For Rotary Switch, we use special order of Saiden's gold plated contacts. All other parts are also carefully selected gold plated new parts.

The wiring material is 0.9mm oxygen free copper single wire, gold-plated Teflon coating is adopted as insulation material which greatly affects sound quality. Wiring is aerial wiring of ASTOR's specialty which makes right and left independent, then improving separation.The foot base is also cut out from the oxygen-free copper round bar, and it is attached by pinching the chamois leather.

The difference between the MC-999NS and the MC-999US series is only the difference whether it is a model that houses a transformer inside the chassis or a model protruding like a chimney in appearance, it is the same model in performance at the degree of splitting into appearance preferences. However, the 999 NS series seems to have high rigidity because it completely encapsulates the transformer, and S / N may be good.

You can choose Hashimoto transformer to be installed from 3 types, A type: HM-3, X type: HM-X, G type: HM-7 depending on your preference.
