Sota SERIES V SAPPHIRE™ AND SERIES V JEWEL


http://www.sotaturntables.com/newtables/sapphirejewel.htm

Both the SERIES V SAPPHIRE™ and the SERIES V JEWEL™share almost all the same design objectives. The main difference lies in the suspension. The SAPPHIRE™ features the traditional four-point spring suspension. The JEWEL™ features the four-point elastic suspension. The new JEWEL™ now comes with the precision S202 tonearm mounted on our wood armboard (Not shown). This newly designed tonearm features a one-piece, tapered arm tube design of near frictionless vertical and horizontal movement. A new SERIES V SAPPHIRE™ would also include the I-Clamp record clamp. The I-Clamping device is available as an optional accessory for not only the JEWEL™, but many other model turntables. The SAPPHIRE™ and JEWEL’S™ shared design objectives include:
