The COSMOS Series IV represents the ultimate expression of SOTA’s critically acclaimed turntable engineering. To neutralise the resonant LP, to couple it hard and fast against the ideal surface, the design objectives of Dynamic Stability (the control of forces present in a dynamic system), Environmental Isolation (the control of forces from "outside" the turntable’s world), Easy Set-up (guaranteed results in all situations), Control Over Vinyl Resonance and Variations (which would otherwise undermine the performance of even the best turntables), and Control Over Power Line Impurities (which are present in all installations and result in sonic anomalies if not controlled), are all addressed in the design of the SOTA COSMOS turntable. With the SOTA COSMOS, turntable design has been carried to its logical conclusion, with the most comprehensive, scientific approach to identifying all the universal variables that undermine pure signal retrieval.
The COSMOS takes ultimate rigidity/mass damping in sub-assembly, arm mounting, motor coupling and bearing structure to new absolutes. The chassis is hung on a floating seismic platform of four-point spring suspension. The chassis utilises a one-piece milled solid aluminum sub-assembly as the foundation. It is so effective that the platter, motor and arm block are mounted directly on the suspended sub-chassis. This provides an unvarying geometry between the motor and the turntable. The dampened sub-chassis and multi-layered platter isolate the arm and record surface from motor vibrations.
The COSMOS utilises SOTA’s internally dampened, multi-layer 15-pound vacuum platter system with the Vinyl Format Mat. The dampened platter with Vinyl Format exactly matches the mechanical impedance of record vinyl - further optimised by its total inertness. The record, mat and platter function as a single, non-resonant entity. The COSMOS platter incorporates SOTA’s inverted bearing assembly design, utilising a polished sapphire thrust plate with zirconium bearing. The SOTA self-sensing record-hold-down system uses a high-tech pneumatic sensing circuit to provide vacuum clamping and maintenance of exact low-pressure vacuum hold-down. The synthesized sine-wave drive 24-pole A/C stepper motor, designed for critical computerised motion use, has electronic speed control and speed change.
Our latest assault on the State-Of-The-Art in LP playback equipment offers several custom finishes to include American Cherry, Piano Gloss Black Acrylic and Exotic Woods as African Rosewood and Macassar Ebony. Your custom choice may too be accommodated. SOTA's latest design enhancement will also feature a removable belt access cover for easy drive belt access.
The COSMOS Vacuum Turntable includes the Cosmos Armboard, for universal tonearm compatibility, and a Reflex Clamp. The Cosmos Armboard is multi layers of acrylic, aluminum and lead in a constrained mode and high polished. The ultimate mechanical clamping system, the SOTA Reflex Clamp assures intimate contact between the record and the mat over its entire surface. The clear beveled-seamed acrylic dust cover with tension hinges is available as an additional cost option.
The Cosmos may also be upgraded to the new top-of-the-line turntable, the Millennia.
Save on your dustcover cost if you buy together with your SOTA turntable.

"... rich and smooth as a brulee"
- Absolute Sound Best Choice, 2009 Buyers Guide
"This classic turntable boasts superior tonal neutrality, soundstaging, background silence and isolation"
- 2008 Editor's Choice Award, The Absolute Sound, Issue #185
"After two years enjoying a Stabi Reference ($8000), it was quickly apparent that the Sota Cosmos ($6600) is sonically superior and closes the gap with the sound of live music. ... this new Cosmos is technically refined, beautiful to see and use, and performs spectacularly. I don't plan to make the same mistake again by selling my Sota. This one may be the last turntable I own."
- Jerry Seigel, 10audio 10/10 LPs
..."its equal cost over twice to multiples its base price...while I know of none...its superior."
"My new Series III Cosmos threw a cavernous stage that was evenly illuminated from front to back and from side to side. The oiled-rosewood cabinet was eye-poppingly gorgeous, with a rich, vivid, high-contrast grain and painstakingly crafted corner joints."
