David-
You win! You have all the record cleaning machines together in one room. You are able to create a stand alone and various combination cleaning of each of your records. I know this is an invaluable experience because you can test, experiment and make your determinations of what is prefered and not prefered. No moral decisions here, just trade offs.
What you could help us all with is document your
standards for clean and dirty. It does not have to be complicated, like
"I removed .03 grams of particulate matter from Record X.." - though I am sure some of our astute hobbyists that read this may want to see some true objectivity. (
And if you can help David and us on this, please come forward)
For your
standard of clean, please take a moment in your own words, document with logical examples of what a clean record is to you. This way the reader has an understanding of what a standard of clean is.
Please do the same for the
standard of dirty. It can be that record store find, that Discogs Disc that arrived from Greece, or the effect of pet dander, dust and oily human hands. Something to that effect that makes the record unsatisfactory to play on your turntable.
What is interesting is this cleaning machine, which includes both "Sonic" and "Vacuum" technologies.
1 What do they know that VPI, KLAudio, and Autodesk doesn't?
2 What have they learned?
3 Is this your next machine?

Beyond this,
4 what other resource could you use to determine that one record machine is better than the other?
5Who could possible tell you what is what when you have all the RCMs right there in front of you?
First my answers to questions
4 &
5:
4: Myles B. Astor or Michael Fremer are verbose in all thing Vinyl. They are professional reviewers that stand as critics that many trust their judgment. (and I forgot someone, please add them because I don't know everyone or everything.)
5: More people who are either invited your house

or has the an
agreeably high performing audio system to confirm what you are telling us. I am sure the people in Q
4 have seen all this in one shape or another, but have not done the extensive test that you have- for one reason or another.
I conclude that you are doing great things for the art of music, vinyl and music enjoyment. You are not a magazine or a website with financial motives. Your quest is the truth. It may not be the absolute truth, but you have climbed the mountain, looked around and you can see things that many cannot. This reason to be, makes you
THE expert, unless someone should challenge your findings. (Then life will get a whole lot more exciting for us in the audience). Keep up your "Audio Philanthropy" and be that maven for all of us to learn from.
