DESCRIPTION Sansui AU 7500 amp / pre-amp
Construction quality is truly exceptional in every respect, and promises unparalleled reliability.

The possibilities offered by the AU-7500 are extensive, both in terms of connectivity and functionality. In addition to its numerous inputs and outputs, it offers two high-quality phono inputs, and the interesting ability to separate its preamp and power amp sections for separate use. Its tone correctors are highly advanced, offering action in the low, mid and high frequencies.

This fine vintage pro integrated is a concentrate of musicality. It offers transparent, warm, rich and dynamic reproduction, where timbres are well respected. A lot of punch, with real dynamic differences, perfectly reproduced; pianissimo are rendered with finesse, loudspeakers with strength. The stereo image is stable and precise, offering great breadth and depth. Linearity across the entire spectrum is perfect, with no overemphasis on any particular register. Low-end capabilities are extensive, offering good substance and body to the reproduction. The bottom end of the spectrum is always precise, articulate and perfectly controlled. The midrange and treble are very fine, rich and fluid. The top end of the spectrum is always loose, without any harshness or acidity.
