Coherent Systems - Aurorasound

Superb vinyl playback sounds utilising innovative design

Aurorasound is a company from Yokohama, Japan. Designer and director Shinobu Karaki has 28 years expierience working for Texas Instruments Japan Inc. He is also a passionate musican, music teacher and an audiophile first grade since many years. His love to music, trained ears and extensive know-how in electronics and integrated circuits makes Mr. Karaki the ideal person to design high-end audio devices.

Aurora's latest development is a fantastic phono-stage called VIDA (Vinyl Disk Amplifier). State of the art semiconductor technology (LCR-type network) and innovative technology combined with old-world craftmanship makes this phono amplifier outstanding in many respects.

Adopted LCR type RIAA device. Unlike conventional NF & CR type for RIAA curve, VIDA uses L (coil) to generate precise RIAA curve, resulting in much fulfilling midranges. With use of the latest semiconductor devices and discrete amplifier circuit, it achieved a complete DC circuit design. As a result, capacitors in the signal path were completely eliminated. High resolution in the low frequencies and reduced distortions, it enables you to enjoy vivid music hall atmospheres coupled with the players positioning on the stage. A large-size MUTE switch together with other functions are aligned in the front panel for improved man-machine interface for user-friendly operation.

High S/N ratio was achieved with use of an external power supply unit, having extremely stable and super low-noise and high speed circuits. Compatible with MC and MM type cartridges. High/Low Impedance Selector switch on the front panel.

Unlike conventional NF and CR type, an ideal circuit design with constant impedance LCR-type RIAA circuit is used. As a result, across the entire frequency range, RIAA curve correction is achieved with constant condition. In the past, vacuum tubes were used with a large chassis, but VIDA managed in a compact size thanks to the latest semiconductor technologies. Each component is placed according to the signal flow in symmetrical and the shortest route. The equalizer circuit uses the renowned Swedish Lundahl filter-coil, which is widely used in the professional equipment, for turnover and roll-off independently.

What all of this adds up to a a world class phono stage that delivers you the real heart of the music, purity of tone, openess, real deatil and a muiscal flow par excellence the Auroasound Vida is a very accomplished performer for Valve and solid state lover alike.

Nick Tate enthusing in Hifi News July 2013

This quintessentially Japanese slice of analogue exotica is artfully engineered to give a coruscatingly incisive and detailed sound, yet one that's genuinely muical too. Impressively devoid of noise, it provides a wide open window onto the vinyl groove yet it never sounds coldly forensic or overly romantic. The VIDA should win many friends here, as it already has in Japan.
