Mobile Fidelity Sound Lab
The first recordings on the Mobile Fidelity label began during the late 1950s and 1960s. Back then, most pressings were on superheavyweight vinyl in order to maintain sound quality. As more and more record companies began to pop up there was an industry wide move to cut production costs which resulted in those flimsy records that your folks had in their collections (think actually being able to bend an LP into a tube shape! Definitely NOT MOFI spec!).
Mobile Fidelity Sound Lab (MFSL) has stayed the course with their production ethos which is definitely more costly, but the sound quality is unbeatable. All albums are remastered from the original analogue master tapes, without compression, and with minimal equalization. During mastering, sound is transferred directly from magnetic tape to disc while the cutting lathe moves at half speed.
Half-speed mastering takes more time than typical mastering, and it presents technical challenges. All technicians involved in creating each record bring an incredible level of expertise, it's a fact that the company has had only a handful of engineers in its history.
So basically, if you want the best in the business handling your record pressing, its MOFI all the way!
