Synergistic Research UEF Record Weight
Synergistic's UEF Record Weight was developed in conjunction with their 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, they 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, they 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 the suspended record weight design.
Synergistic then maximized performance by experimenting with different mass loads in the main stainless steel and carbon fiber 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, they 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, they 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.
When you place the included BLUE HFT on top of the UEF Record Clamp, you experience more air and detail with a cooler and in some recordings, a more dramatic holographic soundstage. This is perfect for listening to artists like Roger Waters or electronic music with dramatic phase effects.
When you place the included RED HFT on top of the UEF Record Clamp you experience rich tonal warmth and greater liquidity with a smoother presentation. This is perfect for vocal recordings like Frank Sinatra and Diana Krall or anytime you want greater warmth and musicality.

"...I could detect more dimensionality and timbral accuracy to the whole performance. The guitar sounds sweeter and more detailed while the percussion sounds tighter and with better PRaT. There is no doubt that the UEF enhances the level of listening enjoyment and reduces listening fatigue quite substantially... In comparison to the UEF, the Shun Mook has slightly more focus and makes the music tonally a bit richer. However, if I had to choose between the two, I would opt for the UEF because, to my ears, the enhanced stability that it renders to the sound stage trumps the improved focus and tonality of the Shun Mook... If you do not have one of those fancy 5-figure or 6-figure price turntables with those crazy heavy platters, you owe it to your ears to try out the UEF. There is a good chance that it will make your turntable sound like you just upgraded it to a model that sports a significantly higher price. If it does not, you can always avail of Synergistic Research's no fuss return policy..." CLICK HERE to check out the entire review

"...with the UEF Record Weight, there was now a more clearly defined sound stage with even more layers of inner detail. Performance at both ends of the frequency range had an urgency and flow that had my head spinning. Mids were even more seductive and tangible. Tone, timbre, and pitch were spot on for a variety of instruments and vocals. The number of goose bump generating spacial cues now seemed endless. I clearly discovered a new bench mark!"

"...it has bigger impact on sound quality than I expected. The sound was more
3D, more clear and natural decay, more instrument separation (but somehow more
full), more treble and bass extension (however, no good deeds got unpunished, I
felt that several new pop LPs' treble got too thrilled, good quality LPs sound
GREAT!). The more surprising was how noticeable the difference between the blue
and red HFTs sounded, you can really tune the sound to your liking, maybe the
difference was amplified by other SR things I have in my system (Atmosphere
XL4, black box, 30 various HFTs, etc)…"
"...I was surprised how effective this record weight was, well worth the investment. Excellent tweak and the technology is real!""...received my long-anticipated Synergistic Research record clamp today!! It comes with two tuning modules (red & blue) that sit at the top of the clamp. It’s deceivingly heavy when I unpackaged it. I fired up my system and let the tubes warm-up for about 15 minutes and let er rip! I listen to my setup hours a day.. I know it better than the back of my hand. I immediately could tell the difference! Holy crap!! I was playing Clapton and my wife from her office came in and told me she thought the guitar sounded live in our house! I couldn’t agree more. The airiness and definition was astounding. I settled on the blue module. It was a bit more settled and warm. Every nuance could be heard but zero harshness. I would recommend this even to my enemies! The red shined playing jazz.. I’ve not yet tried other genres.. I’m enjoying this way to much to switch!! SR outdid themselves with this one!"
