Finding a Vintage Sansui AU Amplifier

Sansui has been catering to sound enhancement needs since the 1950s when it started making tuners and amplifiers. The AU series is one of the iconic lines from the brand that is designed for all users from the fussy audiophile to the low-budget home user. Find some of the top Sansui amps on eBay.

What role does the Sansui X Balanced Circuit play?

Sansui began using the X Balanced Circuit technology in 1984 in its 07’s sixth-generation amplifiers, namely the AU-D607X, AU-D707X, and AU-D907X (see manufacturer site for details). This feature made it possible to reduce the distortion level in amplifiers operating at a wide frequency range. When sound is at peak volumes, powerful currents generate magnetic fields that result in system disturbances. The X Balanced circuit minimises this effect. The big sell of this feature is that it clears up the sound even when played in a large room.

How do you choose a vintage Sansui amplifier?

Sansui offers various vintage tuner options. Purchasing an old amplifier, especially for the first time, can be a daunting experience. Here are some selection tips:

  • Compatibility between intended use of the amplifier and the type of listener. A purist will have different standards than a regular buyer.
  • The quality of sound required from the amplifier will determine the specifications. For instance, the AU-111 falls into the high-standard sound enhancement class with 0.8% harmonic distortion and a frequency response of +1-1dB (see manufacturer site for details).
  • Ask if any of the components have been replaced. You can expect that a vintage Sansui AU-771 may have a few replacements to retain the quality of sound. Knowing about replaced parts will allow you to gauge if the amplifier meets your standards.
What is the difference between Sansui Japanese and international models?

When buying your Sansui AU amp, the terms ‘Japanese’ and ‘international’ will come up in the model names. Sansui used to release products for its local market in Japan and the rest of the market. These tuners and amplifiers are similar in build but vary in model identification. For example, the 07 series had the AU-607 and AU-707 Japanese models, which were the AU-517 and U-717 international models, respectively. Some limited models were only available as Japanese versions, such as the AU-07 Anniversary.
