Thanks for taking the time to do all of that Nando. In the time between my question and your reply, I've researched the heck out of these Sugar Cubes.
As a side note, I'm kicking myself for not jumping in on the Indiegogo campaign. I recollect seeing this kick-start product and didn't take it serious at the time.
It would have been cool to get one at the campaign price instead of these current list prices - which I think are a bit excessive.
In any event, through my research I've learned a lot about these 'boxes' and after some exhaustive time on YouTube, I actually found some thoughtful demo's that show just how effective this click/pop removal process is - on outer grooves, between tracks and even with albums that had literal cracks in the plastic.
What I found even more intriguing is that even though the genesis of these was click, pop and essentially digitized scratch removal... these Sweet Vinyl guys are saying that they have plans to introduce low-level surface noise removal and rumble type conditions too. Pretty amazing stuff and obviously a product that is going to evolve. I can envision this tech being licensed and incorporated directly into turntables some day...
Here's a prime example, one I was looking for, where the dude compares the lead-in grooves with & without the processing.
You'll notice that it does take the 'magic' a few seconds to kick in but when it does, the click/pop/crackle attenuation slope is obvious.
High resolution needle drop comparisons. Take note that at the time of this video it was 2018 and early on regarding firmware development.

I don't know if I would be torturing a nice cart with something as severe as clean breaks in the pressing, but again - pretty damned impressive !
