The HRS Analog Disk is manufactured from a proprietary HRS polymer and billet-machined precise primary metallic part bonded together using a precision transfer mold with less than one thousandth of an inch tolerance for perfect alignment and balance. The weight and final polymer properties are based on years of development tests.
The Analog Disk Light (ADL), with a 315 gram mass, is designed to be used with a very wide range of turntable designs (including low mass and suspension turntable designs). The Analog Disk Light, with its primary metal part manufactured from a high quality heat-treated aluminum alloy, is available in ADL-B (Black Finish) and ADL-S (Silver Finish). Both of the black and silver versions of the ADL are identical in performance.
The Analog Disk Heavy (ADH), with an 850 gram mass, is specifically designed to be used with mid to high mass turntable designs (approximately 15 lb. platter and higher). The Analog Disk Heavy, with its primary metal part manufactured from a non-magnetic stainless steel alloy, is only available in a natural stainless steel finish.
