Sansui - AU-α607 NRA II - 固態整合式擴大機

I sell a beautiful Sansui AU-α607 NRA II integrated amplifier from my hifi collection in perfect working and visual condition.

It is considered as one of the Sansui's last masterpieces and the best works released in 1999 where they implanted all of their engineering knowledge and precise craftwerk in order to come back on big stage.
Unfortunately, due to poor management it didn't happen. However, this amp is their engineering marvel in both, sound and aesthetic. Also it's a piece of hifi history that every hifi collectors should not ignore. Since the alpha series was originally intended for the Japanese domestic market only (100V), it is very rare to find it in this condition outside of Japan. The Sansui AU-α607 NRA II is both a gorgeous-looking and great-sounding amp.
It was rarely used and comes with the original box. All potentiometers and switches work fine without any cracks. This is for sure one of the best ever for sale.

The Sansui's legendary series 07 was the last Sansui series where they implanted all the best, from topology to the best materials to compete with their high-end rivals. With its 19 kg, it is built like a tank providing amazing precision and a soundstage with enough power for most of the speakers. I will send it solid-packed and wrapped in styrofoam.
