Remember the first time you played your favorite record? Wishing you could make it sound as vibrant as the day you brought it home? Layers of grime may stand in your way, but with Revolv’s Supreme Clean Record Cleaning Solution, you're ready to do battle. Supreme Clean is the first solution specially formulated to target the root cause of dirty records: household dust. Biological dust makes up over 80% of household grime by volume, and this is where our solution excels. Biological dust contains a smorgasbord of biota including dead skin cells, insect fragments, pollen, mold, and - wait for it - dust mite feces. In addition to being downright disgusting, it makes your vinyl sound funky, and not in a good way. Once we found our prime target, we put a Ph.D. biologist and a turntable engineer in a room with a stack of dirty records (and plenty of dust), they called a chemist and Revolv Supreme Clean Record Cleaning Solution was born. The proprietary solution reduces surface tension on groove-bound organic substances and disintegrates them on contact. The remnants get washed away along with any inorganics (that remaining 20%) and voila, there you have it: a just-out-of-the-press clean record.

The advantages of DMM (hard surface material) over acetate lacquer cutting (soft surface material) are both sonic and practical: because of the rigidity of the master disc medium, no groove wall bounce-back effects take place after the cutting has been completed. This preserves the original modulation details in the groove walls much better, especially those involved with sudden fast attacks (transients). The improved transient response, as well as the more linear phase response of DMM improve the overall stability and depth-of-field in the stereo image. In addition, disturbing adjacent groove print-through sounds (groove echoes) are reduced in DMM. Also, there is no need to rush the finalized master disc directly into a refrigerator for groove preservation, as in conventional lacquer disc cutting, before processing the master disc to produce matrices for the pressing of the records.

 Direct metal mastering (DMM) is an analog audio disc mastering technique jointly developed by two German companies, Telefunken-Decca (Teldec) and Georg Neumann GmbH, toward the end of the 20th century after having seen the same technology used by RCA Princeton Labs for its Selecta Vision videodiscs in the late-1970s.

Records manufactured with this technology are often marked by a "DMM" logo on the outer record sleeve. Many current production high quality pressings, as well as standard production LPs from the 1990s, only indicate its use by inscribing "DMM" in the lead-out groove area of the disc.

Neumann was responsible for manufacturing the actual DMM cutting equipment as part of its VMS80 series lathes. Unlike conventional disc mastering, where the mechanical audio modulation is cut onto a lacquer-coated aluminum disc, DMM cuts straight into metal (copper), utilizing a high frequency carrier system and specialized diamond styli, vibrating at more than 40 kHz (i.e. 60 kHz) [1] to facilitate the cutting.
