Sorane SA-1.2BCS Tonearm

Based on the award-winning SA1.2 tonearm, the Sorane SA-1.2BCS adds additional features for the vinyl enthusiast. Silver internal wiring for superior signal to noise ratio. Silver headshell cartridge leads. The SA1.2BCS offers the choice of either positive or negative balance (convertible centre of gravity), via two alternate counterweight stems (the first tonearm ever produced with this
feature in the world).

Sorane SA-1.2BCS Tonearm

■ What is “positive balance”? The position of the counterweight
shaft is below the centerline of the vertical bearing, moving the
center of mass below the fulcrum point.

■ What is the outstanding feature of “positive balance”?
Unconditional stability, with the tonearm, always returning to the
same resting location.

■ What is “negative balance”? The position of the counterweight
shaft is slightly above the centerline of the vertical bearing, moving
the centre of mass above the fulcrum point.

■ What is the outstanding feature of “negative balance”? The
tonearm automatically compensates for warps without the aid of
extraneous devices, such as springs, servos, etc..

The way to change Positive/Negative balance in Sorane SA-1.2BCS
As shown in the photos, SA-1.2 BCS is equipped with 2 counterweight shafts, one is “Positive” shaft (Installed, upon delivery of the product), while the other is “Negative”, which are replaced
interchangeably by your hands with attached Allen key

Sorane Tonearm Range Shared Features:
CNC, machine-tooled and hand-assembled by skilled Japanese craftsmen. This highly skilled and delicate hand-assembly differentiates Sorane tonearms from mass-produced Japanese tonearms. With standard quality goals, high-volume production tonearms are manufactured by die-casting and semi-automatic assembly line processes, to keep production costs low.

The SA-1.2 and ZA-12 will produce rich and tight bass, coming from the extremely rigid rectangular shaped armwand. Skilled hand assembly does not simply mean “combining
the constituent parts by hand”. Skilled hand assembly involves measurement, adjustment and hand-fitting to produce optimal interface between machined surfaces. Once completed, the fitment between every part is ideal, satisfying the necessary conditions for chatter-free reproduction of analog sound. Most importantly, the key to tonearm quality is highly sensitive and delicate motion, for which the bearings are the determining
factor.

Gimbal-bearing designs for excellent bass, dynamic sound and imaging, as well as unconditional azimuth stability (Which is the biggest problem for conventional uni-pivots bearing).

For SA-1.2, SA-1.2B, SA-1.2BCS, (As attached photo) two sets of fine radial bearings are installed for both horizontal (set in the bearing stem column) and vertical (further small bearing at tonearm wand) suspension. This assures audiophiles of smooth tonearm function, greater longevity, better consistency, and enhanced ability to track warped vinyl.

(In Sorane SA-1.2BCS, negative-balance selection is to follow more precisely to warped vinyl)(More versatile bearing of “Double Bearing Pivot suspension” is
applied to ZA-12, as mentioned after.)
