MoFi UltraDisc One-Step

Instead of utilizing the industry-standard three-step lacquer process, Mobile Fidelity Sound Lab's new UltraDisc One-Step (UD1S) uses only one step, bypassing two processes of generational loss. While three-step processing is designed for optimum yield and efficiency, UD1S is created for the ultimate in sound quality. Just as Mobile Fidelity pioneered the Ultra High-Quality Record (UHQR) with JVC in the 1980s, UD1S again represents another state-of-the-art advance in the record-manufacturing process. MFSL engineers begin with the original master recordings, painstakingly transfer them to DSD 256, and meticulously cut a set of lacquers. These lacquers are used to create a very fragile, pristine UD1S stamper called a "convert." Delicate "converts" are then formed into the actual record stampers, producing a final product that literally and figuratively brings you closer to the music. By skipping the additional steps of pulling another positive and an additional negative, as done in the three-step process used in standard pressings, UD1S produces a final LP with the lowest noise floor possible today. The removal of the additional two steps of generational loss in the plating process reveals tremendous amounts of extra musical detail and dynamics, which are otherwise lost due to the standard copying process. Every conceivable aspect of vinyl production is optimized to produce the most perfect record album available today.

UltraDisc One-Step: The Future of Hi-Fi

Everything begins with the meticulous cutting of a set of lacquers for a strict number of records to be pressed. After being cleaned with a proprietary chemical, the lacquers are rinsed in de-ionized water and dipped in stannous chloride, enabling pure silver to adhere to the surface. This leaves a pristine, extremely intricate silver layer. The lacquer is then mounted onto a conductive copper bar and immersed into a tank with nickel anodes at 98 degrees. As electricity is applied to the silvered lacquer, the nickel begins to deposit onto the lacquer, while preserving the integrity of the grooves. The nickel-plated silvered lacquer is then placed into a high-speed rotary tank at 120 degrees and spun at 88RPM to ensure the even application of a nickel layer. Once the desired thickness of .012" is achieved, the disc is removed from the plating tank and the nickel convert is separated from the lacquer. At this point, the convert is formed into a single-use record stamper. This first-generation convert is used to make the pinnacle of audiophile vinyl that literally and figuratively brings listeners closer to the music.

SuperVinyl

MoFi SuperVinyl is a new proprietary compound developed by NEOTECH and RTI to address two specific areas of improvement: noise floor reduction and enhanced groove definition. The vinyl composition features a new carbonless dye (hold the disc up to the light and see) and produces the world's quietest surfaces. This high-definition formula also allows for the creation of cleaner grooves that are indistinguishable from the original lacquer. Mobile Fidelity Sound Lab feels SuperVinyl provides the closest approximation of what we hear in the mastering lab.

GAIN 2™ Mastering Technology for UltraDisc UHR™ Hybrid SACD and UltraDisc II™ 24kt Gold CDs

For over twenty years, Mobile Fidelity Sound Lab has continually searched for the ultimate audio experience. During this search MFSL engineers and associates created The GAIN™ System, a proprietary mastering technology which brought warmth and ambience to the compact disc format. A few years ago - with higher resolution formats on the horizon - the vision of GAIN 2™ began. As it stands today, GAIN 2™ is one of the greatest technical advancements in analogue and digital technology in the last ten years. It consists of a series of critical modifications and new components to Mobile Fidelity's proprietary mastering chain.

We feel that GAIN 2™ has come extremely close to meeting this goal. The key accomplishments of GAIN 2™ System are 1) the ability to extract all the musical information as possible through the Ultra High bandwidth analogue tape playback system with proprietary custom tape playback heads, reproducer electronics and 2) transparently capturing and storing that information with the Direct Stream Digital recording system.

GAIN 2™ Ultra Analog™ System for Vinyl

GAIN 2 Ultra Analog™ is a proprietary cutting system built and designed by legendary design genius Tim De Paravicini, with consultation from one of MFSL's founding fathers – Stan Ricker, an audio engineer responsible for many of MFSL's most heralded past releases.

The GAIN 2 Ultra Analog™ system is comprised of a Studer™ tape machine with customized reproduction electronics* and handcrafted cutting amps that drive an Neumann SX74 cutting head on a restored Neumann VMS-70 lathe. (*It is worth noting that independent studies have confirmed that the GAIN 2 Ultra Analog™ system can unveil sonic information all the way up to 122kHz!)

First and foremost, we only utilize first generation original master recordings as source material for our releases. Our lacquers are then plated in a specialized process that protects transients in the musical signal. (Due to this process, there may be occasional pops or ticks inherent in initial play back, but as the disc is played more, a high quality stylus will actually polish the grooves and improve the sound). We further ensure optimum sound quality by strictly limiting the number of pressings printed for each release. These limited editions, in addition to being collectors' items, ensure that the quality of the last pressing matches the quality of the first.

As you can imagine, all these efforts involve a tremendous amount of time, technology, cost and effort. The introduction of GAIN 2 Ultra Analog™ maintains Mobile Fidelity Sound Lab's position as the world's leading audiophile record label, where a passion for music with extraordinary sound quality matters most.
