La Luce proper The La Luce 'table is described by Mrs. Spotheim pronounced Schpot -hime as a low–energy-storage, direct-coupled, nonsuspended design driven by a stand-alone motor and a belt of elastic thread. Spotheim recommends that the 'table be placed on a very dead-sounding platform, one immune to feedback and drumming effects. The motor should be placed on a separate platform that doesn't make contact with the 'table's platform. The hefty, Bauhausian motor sat on a Signal Guard II Resonance Attenuation Platform fitted with PolyCrystal spikes on a separate PolyCrystal equipment stand set at about the 9:15 position. Arm base The impressive-looking La Luce arm base is machined from stainless steel and consists of three main parts: the ground-plate, the VTA pillar, and a canted horizontal platform that extends out from it. The 15mm-thick ground-plate is bolted directly to the 'table and supports the overhang micrometer, its locking screw, and the VTA pillar's horizontal rails. Each full turn of the overhang micrometer knob changes the distance of the pivot from the spindle by 0.5mm 0.019685 forward or back over a range of 38mm 1½ . The horizontal platform either side of the VTA pillar is raised and lowered with the VTA micrometer knob. Reference marks are engraved on a plate around the base of the VTA knob adjustable during play to keep track of your position. The platform carries the main pivot. Just next to it, the azimuth micrometer pillar raises and lowers a small platform on which a secondary traveling pivot rides. The horizontal platform also carries a central grounding post that extends from the canted edge on the far side of the platform. The main grounding post is a small, beautifully crafted aluminum cylinder, adjustable for angle, that features a soft-bite clamp that gently keeps the arm wires out of harm's way. On the near side of the platform sits a pillar with yet another micrometer-operated device that raises and lowers the arm-lifter mechanism. Setting its height relative to the arm is easy and convenient, regardless of VTA. The edge of the platform becomes obliquely angled just beyond the lifter micrometer pillar. Pointing at an adjacent plate, it indicates the VTA setting—the tip is at the same horizontal level as the pivot tip. The VTA height indicator, which is attached to the base ground-plate, has an engraved scale facing the adjacent oblique-angled tip of the platform. Each of the longer lines on the scale above and below the center line represents 1.25° of change at the pivot tip. Calibrating the zero line with the tip of the horizontal platform marks a reference point for VTA when it's changed. The titanium cartridge mounting platform headshell is crimp-connected to the armwand, which in turn is crimped at the pivot end to a titanium block. Finishing it off, Cardas pure-copper arm wires are twisted together, reinforced, and run in parallel through the arm to extend up out of the titanium block, where they're terminated with Cardas rhodium RCA female connectors.
