Turntable Soulution 787 Turntable

A reference linear-tracking turntable in which the platter moves instead of the arm

The Soulution 787 is a reference turntable with linear groove tracking, built on an unconventional principle: instead of a sliding arm, the entire platter moves laterally beneath the arm. The eight-inch pivoted arm with minimal deflection is mounted on an isolated sub-chassis with controlled resonances, so it remains constantly aligned with the linear tracking path. Thanks to this, the groove tracking error stays within a maximum of 0.15°, from the outermost to the innermost groove of the record.

The complete platter sub-assembly consists of the platter, a sub-platter with a high-precision sintered, low-friction magnetic bearing and a drive motor with precious-metal contacts. The whole assembly glides along polished shafts beneath the arm, while the arm's position is monitored by ultra-precise inductive proximity sensors that control the lateral traverse motor. Power is supplied by a switch-mode supply with efficient DC-DC converters and extremely low-noise, fast linear regulators that generate all operating voltages.

The architecture of the 787 eliminates the friction and unbalanced forces typical of conventional linear tonearms, where the arm is drawn toward the inner grooves by lateral forces at the outer edge of the record. At the same time, it retains the advantages of a low-friction pivoted arm, but without skating force, tracking error or demanding geometric setup. The result is stable guidance of the stylus in the groove, precise localisation of instruments within the stereo image and a clarity of detail that does not change even in the final passages of the record.

The arm is also compatible with high-compliance cartridges, uses precious-metal alloy wiring and allows adjustment of both VTA and azimuth. Once the platter moves to its parking position, the arm swings aside, making record changes easier. The turntable offers 33 and 45 rpm speeds and one pair of RCA outputs.
