We at Pauler Acoustics have developed a new record format (DMM-CD), which contains only the desired sound and typical tonal qualities of a vinyl record. Our method is based on the fact that the "vinyl sound" in the first place is created as a result of transferring an analogue or digital master on to a copper-coated stainless steel disk (Direct Metal Mastering).
The crucial step to DMM-CD:
Our Neumann VMS-82 cutting lathe functions as the original record player, because after the cutting process, we leave the copper master on the lathe held firmly by vacuum suction. This way the disc has no vertical or lateral movement, which would affect the tracking of the pick-up stylus.
Using the best possible components, we play back the signal from the freshly cut groove. The components used are: an EMT TSD-15 Pick-up, a factory built special version of EMT’s legendary Broadcast TONDOSE TSD-15 and incorporates a diamond made from a square natural rod. This diamond is refined with a highly sophisticated shape with multiple facets resulting in a frontal parabola measuring 17 x 25 µ. This diamond quality secures not only very little distortion, but also very low FIM (Frequency Intermodulation Distortion). Moreover we decided to use an EMT 997 pick up arm and a top of the range EMT JPA66 valve pre-amplifier. With critical listening tests, this combination has proven to us to be the optimal chain when it comes to obtaining a sound as close as possible to the master.
The output of the JPA66 cutting curve equalizer transfers the analog signal to the A/D converter, a "Meitner EMM Labs adc 8 MK IV". This is still regarded as a reference for the best possible conversion to the 1-bit Direct Stream Digital format. The DSD signal is then recorded at a sampling rate of 2.8224 MHz on to our SADiE DSD8 mastering system. Later, on the finished Hybrid-SACD, you will find this true 1-bit DSD layer and also a generated CD format at 16-bit/44,1kHz.
To enhance the tonal quality of the DMM transfer for the DMM-CD, we cut the music programme at 45 rpm, and basically only use the area between the two zero crossings of the cartridge arm. This is the area where the geometry of the pick-up arm is optimal. However, this decision costs a few copper blanks more, as it reduces the running time per side as opposed to the pressed vinyl LP.
With this new sophisticated process, a new digital recording media (DMM-CD) has emerged retaining the original sound of a Vinyl-LP but without the unwanted side effects. The DMM-CD/SACD gives you the direct sound of the DMM Copper cut - without having to go through the stages of pressing a record.
Direct Metal Mastering is a quality term for authentic records dubbing. We have deliberately opted for the then current state of the template cutting technology - just before the CD 1982 their (alleged) triumphant launched.
The DMM copper master knows no pre-echoes and no loss of high frequencies, provides longer seasons and has much less noise than a cut in nitro lacquer film "Urschallplatte". A reduced electroplating DMM dies in the pressing plant also benefits the quality and the price.
Hendrik Pauler is home Pauler Acoustics / stockfish specializes in the demanding process of records dubbing. Here the stockfish vinyl productions are not only cut, but also numerous other labels use the long-standing experience in Disc Cutting Pauler Acoustics. In Northeim the Direct Metal Mastering system VMS 82 of the Berlin company NEUMANN is used for.
