Featuring a virtuosic lineup that counted a trombonist, trumpeter, keyboardist, guitarist, drummer, bassist, woodwind expert, and several vocalists, Chicago peruses territory on its multiplatinum 1969 effort that remains singular in execution and delivery. Here, hard-driving rock gets paired with a similarly forceful power brass section that yields energetic aural cross-sections that marry loose improvisation and focused creativity like nothing heard before. 

Chicago Transit Authority has its cake and eats it, too, traversing both avant-garde approaches and pop techniques. Such pioneering methods earned the group three hits—“Does Anybody Really Know What Time It Is?,” “I’m a Man,” and “Questions 67 and 68”—all longtime standards. Breaking down borders, the unified jazz and R&B strains speak to compositional possibilities that, arguably, initiated fusion’s entrance into the mainstream. 

Mobile Fidelity believes that mastering systems should be neutral and transparent. The essential idea is to unveil all the detailed musical information on the original master recording without adding deterioration, coloration or other sonic artifacts. 

It is worth noting that Mobile Fidelity Sound Lab stands out as one of few record labels that independently invests in research and development of audio technology. With proprietary innovations such as GAIN 2™, general music enthusiasts and audiophiles alike have reaped the benefit of a higher consumer audio standard without investing in costly new hardware. Mobile Fidelity is pleased to work with a variety of engineering legends and companies including Tim de Paravicini, Ed Meitner, Pass Labs, Theta Digital and Sony Electronics. 

Our joint efforts to seek out the ultimate audio experience, has resulted in significant advances for the technology of music reproduction. 

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.
