Watched V1 in it's entirety and just a bit of V2.
V1 definitly sounds like groove damage. The pop-clicks are not random as if it was merely entrapped dirt dust the pop-click would be a lot more random. The pop-click is regular, at a certain part of the LP possibly due to a major scratch.
When you hear the pop-click, make a mental note of where on the label the stylus is at the exact time you hear the pop-click..... ie right when the needle passes the "d" in SIDE 1.
Remove the LP from the tt and then radially move from the spindle hole to the "d" outwards towards the edge approxmately where the tonearm tracks into the song / cut. Look for groove damage, scratches.
I've had very good results with my Spin Clean, however, if there is additional noise ie in V2 (as the noise / pop-click is more random) I further concentrate / clean / scrub using my MoFi brush:
around where I hear noise.
This will eliminate most all of the dirty / dusty noise on LPs, leaving me with pops-clicks from physical damage done to groove walls.
As mentioned in a post above, I find the SC cleaning solution somewhat lacking and use my a homebrew with good results.
Other possible explanations for more perceived pops-clicks:
1. Have you recently upgraded your needle? from lets say a more foregiving conical?
2. Changed VTA and / or tonearm height?
3. Changed cartridges?
4. Have you aligned everything perfectly?
5. Adjusted VTF?
6. Have you examined the SC's brushes? are they nice and smooth with NO hard protrusions? ie a stiff nylon corner, plastic protrusion, trapped staple?
Do you have any new LPs? that you've put through the SC? and have them come out with more noise?
For me, the SC does a nice job of removing filth especially on older used garage, thrift store, flea market, etc... LPs.
Fred and try a different cleaning solution / homebrew.....
