Our UEF Record Weight was developed in conjunction with our new MiG SX footers and so shares many of the same sonic traits, including the ability to dramatically expand the scale and layering of your soundstage while improving timbral accuracy and tonal density. During the design phase, we pursued two competing designs simultaneously. One was a record clamp that locked to the center platter pin, and the other was a suspended record weight. Initially, we felt the record clamp would offer better performance but quickly discovered one significant drawback, once locked down the clamp becomes an extension of the platter and this prevents minute variations in lateral and vertical movement, thus compressing the soundstage when directly compared to our suspended record weight design. We then maximized performance by experimenting with different mass loads in the main stainless steel and carbon fibre body and various leaf spring suspensions that form the connection between the mass of the stainless steel and the tungsten carbon bearings that make contact with the record itself. Of course, we also experimented with different bearing materials, but just as with MiG SX, tungsten carbon quickly proved superior to other materials like brass, bronze, and stainless steel. After fine-tuning the mass and the suspension, we voiced the record weight with an internal UEF element and an external UEF option that allows you to choose between two sonic balances in the form of a Red and a Blue HFT specially voiced to deliver air and detail or warmth and liquidity. As with other Synergistic Research products, the UEF Record Weight is sold with a 30- day money-back guarantee so you can spin your favorite records with ample time to make a final decision risk free.
