Company page · written by KirmussAudio · confirmedDiscovered in 2014 where there is a pressing oil/release agent that surfaces at the pressing plant that allows a record to "pop out" of the press, that when cools, not only is there an oil present, but as it cools, contaminants around the press that land onto the oil get fused into the record's groove, cause of those nasty pops in new records. In 2017 the KA-RC-1 was released: a process that uses ultrasonic technology coupled with record ionization, that removes the oil and the fused in dust particle(s). There are also films left over from prior cleaning processes that are air, vacuum or spin dried onto the record. The needle fights with this, the release agent, as well as sandwiched between both, the film deposited by the outgassing of the plasticizer while in the record’s sleeve. Cause of most of those visible scratches on the record and ticks heard. Where other processes surface clean and shine for look, Kirmuss patented ultrasonics with resonance and record ionization lets your needle discover the music once hidden. “After 1 year of testing: "Best of all when I played it, (after record restoration), HOLY CRAP!“, “The top end fully restored, the backgrounds were super quiet, transients were sharpened, the inner detail in Peter Townsend’s rhythm guitar strings (Tommy) produced an almost new listening experience.” “I wholeheartedly endorse the Kirmuss System”. “It does not clean, it does restore!”.. “AND ITS AFFORDABLE!” Michael Fremer, Stereophile A recommendation: “While skeptical at first, Charles Kirmuss has proven to me everything he advertises is true and I cannot disprove. Recommended. Restores, not just surface cleans.” Michael Fremer, TrackingAngle.com Now at the CAF 2026 show, Marketplace Booth 9, the North American premiere of our compact cassette tape cleaning and rejuvenation machine!
