Ultrasonic cleaning with kirmuss and loss of high frequency details.


I just purchased the kirmuss US machine and diligently followed their instructions to cycle through minimum 3 cleanings of 5 min each with their surfactant applied each time. Upon testing my favorite vinyl and critically listening through my headphones I am convinced I’ve lost high frequency details. My background is completely silent and ticks and pops have been reduced by 95% or more. So cleaning wise it did the job. Anyone here ever experience loss of high frequency detail after repeated US cleaning? Now I’m worried I permanently damaged my favorite vinyl somehow. Please let me know, thx.

Personally, I hope I never get to @lewm ’s feeling. I feel that the cleaning process brings me even closer to "the connection" I feel with any particular artist’ music.

Truth in advertising.... I struggle with this all of the time. This ONE thing that really keeps me from coming close to bringing any product to the public (in my dreams). It seems the norm is to exaggerate your products strengths, all the while knowing those so-called strengths are maybe 1% of anyone's (end user) best experience. I HATE thinking about it!
My experience with US cleaning leads me to conclude with @bdp24 on the frequency aspect. I own a Audio Desk and a DIY machine as @rushton proposed w/the filtering system. I recently saw a US machine with a frequency sweep mode, although it still operates at 40khz, seems to make sense. I’ve noticed from experience with my 6 liter tank and the Vinyl Stack spinner, that even with a 4 lp ability, I find the best cleaning is done with two lp at a time @ 45C, on the slowest rotation, for 40 minutes.

Kirmuss notes his positioning of his four devices as critical to the cleaning performance. That makes perfect sense in a way but as a layman, I’d question that somewhat, as these frequencies are being transmitted through water. It seems to me that water would break up the flow of these frequencies? So, this machine I saw on Amazon w/ the "sweep" mode @ under $300 makes sense.

Kirmuss makes a lot to do about the application of his fluid (with the same brush, over & over) yet says not one word about using the same fluid/water over & over without a filtering system. Very surprising!
