1) Visit our KirmussAudio YouTube channel. Two short video clips show two records that were brought in by their owners at the CONSAM and Kirmuss-Margules audio event in Mexico City this past November.

Records brought in for us to restore were previously cleaned using a vacuum based cleaning machine and a 120KHz ultrasonic.

As we do at all events, a before and after auditioning was performed.

Connected was a spectrum analyzer. See, hear and feel the results of Kirmuss Record Groove Restoration. The KA-RC-1 is not a surface cleaner or shiner.

Unlike peers, we state and guarantee a 1.3 to 1.4 dB gain over floor and an 8% increase in frequency response in new pressings,.

Between 3 and 4, at times upwards of 9 dB gain over floor and 18-28% increase in frequency response in vintage records or records of provenance unknown.

2) Visit us at the SOUTHWEST AUDIO SHOW, Dallas, Texas at the Hilton Anatole, March 15-17 2024, across from the registration desk!
Bring us a record to restore!

3) Also, at AXPONA 2024 in Booth 9200, we are INTRODUCING ALPHASON tonearms from the UK. Mike Knowles in 1985 developed most of the tone arms sold globally, some sold by SME and of which his 100S saw 25% of its production sold to the US through SOTA. Absolute Sound in those days called it the best tonearm in the world. Meet Mike at the show and see his new products in our booth!


Q: How many records can I clean with one "bath"?

A: You can clean two 33 1/3, one 45, and one 78 at the same time. The spacing between the records is crucial to the process, any larger number of record within the same space reduces the advantage of the ultrasonic that works the surfactant into the record grooves.

To the bath: We suggest you change out the distilled water with the 1.4 ounces of 70% IPA in the tank after restoring between 15 to 20 records or when the water becomes murky. Severely contaminated records will show up with murky water in the tub. Do not let the water stand in the restoration system overnight. It will grow fungus once the alcohol has evaporated. Please discard.

Q: How long will that Surfactant bottle last before I need to replenish it?

A: You should be able to clean between 100 and 150 records before requiring a new spray bottle. (60 mL). The number of applications depends on the number of 5 minute cycles that you require to restore the record. Eight applications would see less records restored, around 60.

Also available: a 300 mL refill bottle. This is approximately 20% lower in cost.

"...To say that I was pleased with the performance of the Kirmuss was to issue a laughable understatement. The KA-RC-1 not only removes troublesome  noise efficiently, to give new life to your vinyl, it also provides a level of sonic transparency that is truly astounding. Once you hear the effects yourself, you’’ realize that you’ve never actually heard your record collection. 

...Not properly."

"I have to declare that the KARC-1 is the best record cleaner on the market. Bar none.​"​


HiFi World Magazine (January 2019)

"The Kirmuss KA-RC-1 is the best commercial ultrasonic cleaner currently available on the market."

The Audioman

(on-line review January 2019)

"Kirmuss Audio’s "In The Groove" Ultimate Ultrasonic Vinyl Restoration System makes the process of using this technology more affordable. You can RESTORE your 33 1/3, 45's and 78's simultaneously!​​"

Andre Jennings


The Kirmuss system should not be seen as simply a record cleaning machine, it is a professional grade archival system that has been made affordable to anyone wanting to preserve or restore their vinyl collection and as such thoroughly deserves 

Hifi Pig’s Outstanding Product Award.

"Billed as a record groove restoration system (and not a record cleaner), You will be rewarded with a better soundstage and truer instrumental timbre". " As such receives Absolute Sound's EDITOR's CHOICE AWARD".



"I wholeheartedly endorse the Kirmuss System” ;   “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." 


 “Works as promised,  and it’s reasonably priced.”     

MICHAEL FREMER, "Dr. Analog to many."

Stereophile Magazine July 2019

“Dr. Kirmuss, I want to share my absolute delight and astonishment with your system.  Over the past five decades I have used many DIY and professional cleaning systems ,.none of those systems have come close to the sonic benefits I am experiencing with this system, …it is like opening a window, simply dramatic. What I now hear from them is a revelation. This cleaning solution is simple, effective and impactful.” Thank-You, Kind Regards,
