G-700i
Vibrantly pulsating, truly capturing
  the essence of the artist’s passion.

This unit has been developed as a line preamplifier that combines the rich and mature sound of the G-70 with the expressive power of the flagship model G-1000. Through careful circuit design and countless listening tests, we have achieved top-class specifications and refined expressive capabilities.
It is neither a downgrade of the G-1000 nor an upgrade of the G-70, but has the expressive power appropriate for this class.

The newly developed 50-point ATT unit uses MELF-type resistors that have been tested through listening sessions. By mounting them on a high-quality rotary switch and housing them in a copper case, it achieves outstanding information capacity and silence.

As a transparent presence that manipulates music at the center of the audio system, it brings out the passion of the performance with its vitality and expressiveness while faithfully and honestly reproducing the sound source.

Features

Audio Note Original Attenuator Unit

Equipped with a 50-point attenuator using newly developed high-quality MELF type resistors.
The most frequently used function of a preamplifier is volume control. In developing a new attenuator suitable for the middle class, we conducted many trial listening tests.
As a result, MELF-type resistor was adopted. By mounting it on a high-quality rotary switch and enclosing it in a copper case, we were able to achieve an outstanding level of information and quietness. It is placed in the center of the chassis to match the symmetrical amplification section.

Line amplifier unit

Decoupling capacitors are independently placed near the module to minimize the signal loop.
It is designed with consideration for connection with transistor amplifiers, with an output impedance of 400Ω and a cutoff frequency of 18.5Hz (with a 20k Ω load).

Power supply, the shunt heater circuit

By housing the power transformer in a separate chassis and making it independent of the amplification section, the influence of vibration and magnetic leakage is eliminated to the maximum extent. Additionally, while having a separate power supply section, it is designed to fit into a single audio rack.
The newly designed transformer and choke undergo appropriate damping treatment through repeated listening tests. The ripple filter and decoupling capacitors are clearly separated in design and implementation to create a powerful power supply section. The decoupling is composed of three types of capacitors, contributing to a well-balanced sound with each characteristic suppressed. The newly developed shunt-type heater power circuit eliminates ripples through a large capacitor group, contributing to a stable and spacious sound reproduction.

Ultra-high-quality parts

ATT unit, copper main chassis, pure silver foil capacitors, pure silver lead resistors, SSW wiring material, pure silver shielded wire, silver-palladium plated RCA jacks, zirconia vacuum tube sockets. In addition, high-quality original components such as custom-made electrolytic capacitors, power transformers, and chokes are used. Carefully selected components are effectively placed throughout the unit.
