Description
Sansui AU-D11 Integrated Amplifier For sale is the Sansui AU-D11. The amplifier has been serviced, partially recapped and fully tested. The changes/upgrades are listed below. SEE PHOTOS for imperfections that could not be remedied. THIS AMPLIFIER HAS BEEN FULLY TESTED FOR OVER 3 MONTHS WITH NO PROBLEMS. From a period review: On the test bench, the Sansui AU-D11 proved to be everything its manufacturer claimed. It is an extremely low-distortion, wide-band, low-noise, stable amplifier with almost all the control functions that might be desired by a serious audiophile. In our view, the excellent tone controls, flexible input and tape-recording facilities, and built-in MC head amplifier more than compensate for the amplifier’s ineffective filters. The absence of separate preamplifier outputs and power-amplifier inputs did not disturb us, since it is perfectly possible to use the AU-D11 as a power amplifier alone by driving its aux inputs with the tone controls bypassed. The AU-D11 has no loudness control, but its tone controls can do a far more effective job of correcting for hearing changes at low volume levels than any conventional “loudness control.” One might legitimately wonder why this amplifier carries such a high price tag, and taking off the handsome wooden cabinet provides at least some of the answers. It is a far cry from some of the starkly “basic” amplifiers we have seen and from the thrown-together look of some low-price products. It has an impressive number of components, with no evidence of skimping anywhere, and its internal construction would do credit to the most respected “high-end” manufacturer’s standards. All the metal surfaces are copper plated. The massive power supply occupies most of the center of the amplifier, and we counted more than 65,000 microfarads of filter capacitance in its power supply (far above the average for amplifiers of this power rating). Furthermore, the “wiring” between the filter capacitors and from them to the rectifiers is not wire at all: these connections are made with “U”-shaped metal channels, no doubt in the interest of achieving minimum power-supply impedance. To assess the Sansui AU-D11 properly, one should think of it as a state-of-the-art amplifier built for the most discriminating audiophile, rather than just another high-price product from a large Japanese manufacturer. Assuming that its power is adequate for the intended use and that no serious objections are raised to any of its control features (or lack thereof), we believe that there is no better amplifier to be had today. Naturally it sounds as good as amplifier can sound. This flagship of the Sansui line is an amplifier whose performance, combined with full protection for itself and the speakers, may possibly be equaled (though not cheaply) but is not likely to be surpassed. If something better came along we doubt that it could be measured with today’s instruments, since ours were operating at or beyond their design limits during our tests of the AU-D11.
