I have the same machine. I don’t do what they do. All I do (for brand new or never cleaned records) is to manual wash and vac with a traditional machine then throw it in for a 5 min cycle. Then rinse clean and vac dry. Works well and it unlocks an amazing amount of detail. Mostly spatial information. No detectable loss in high frequencies. For previously cleaned records, I just throw it in for a 5min cycle, then rinse and vac dry.
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.
