The one-step LP boxes from MFSL are the benchmark in the area of ​​audiophile re-issues and are qualitatively superior to the other productions of the most famous remastering studio in the world. What is special about the LPs is not only a new vinyl granulate without carbon colorants, which is used at RTI in Camarillo, but above all the one-step process of LP production. You can only get closer to the sound of the master tape in the MFSL studio in California.

This means the following: In normal LP productions, the lacquer cut is transformed into a first “father stamp with an inverted groove structure”. A “mother stamp” with the correct groove structure is then created from this. This then creates the actual pressing stamp with an inverted groove structure and is used to press the actual LP with the correct groove structure. This approach allows you to press almost any number of LPs with just one varnish cut.

In the one-step process, this is all much easier. The actual lacquer cut itself is converted directly into the press stamp with which the LP is made. So two steps of mechanical conversion are eliminated. Unfortunately, you can only make a limited number of LPs with each varnish cut. If more than a few hundred LPs are to be produced, several varnish cuts are required. MFSL has issued the motto that a new set of press stamps should be used every 500 copies. This means that with a print run of 7,500 copies, fifteen sets of four varnish cuts are used. Since things sometimes go wrong in production, 18 sets are usually created at once. This means that 72 varnish cuts are created from the master tape using the half-speed mastering process for the double LP. By hand, one at a time. Every day the created lacquer cuts are flown expressly to RTI for reworking and then a test pressing has to be created for each side and also listened to in the MFSL studio. A time-consuming and also expensive process that results in an expensive product and high collector demand.
