Sansui engineers working on the SR-525 made no claims or promises until they were sure of their results.

They thought they were on the trail of a significant breakthrough in turntable excellence, and they were right.

Now that the SR525 is ready for marketing, their secrets can be revealed.

One, they have refined the rotor position sensor mechanism in combination with a 20-pole, 30-slot brushless DC servomotor with a saturable core to perfect the most accurate, most silently running direct-drive system the industry has ever seen.

Two, they have lowered wow and flutter to a negligible 0.03% and boosted S/N to a high 64dB with the use of a mirror finished spindle and sleeve combination.

Three, they have the finest Sansui S-shaped tonearm, incorporating a special resonance-absorber for it to totally eliminate resonance, and used a knife-edge support system to ensure the lowest friction performance they've ever achieved.

And finally, the SR525 is equipped with a solid, die-cast aluminium headshell, a stroboscopic pitch control system, electronic speed-change controls and a number of other advanced features to further guarantee maximum performance excellence and ease of operation.

The biggest secret is how Sansui has held it's price to and even below the level of comparable belt-drive models.
