Quite agree, Tol! I couldn't tell it better! The thing is that there are so
many softwares and "gadgets" out there that looks beautiful, but often works
quite different. Better go for the best possible copy, but that is sometimes
easier said than done! Another fact is that especially British HMV discs
often looks quite mint, but plays with lot of crackle.
All the best

Hi Jan,
I think it's a fool's errand to find anything analog or digital that can
sort out music vs background noise beyond a very small degree. Ticks and
pops are relatively "easier" because they are impulse noises, higher in
level than surrounding music. However, as we've discussed, most automated
tick and pop removers also decimate musical transients if used to any degree
beyond very conservative.
You can't pick the diamonds out of the turds with grooved disks, it just
doesn't happen. So your best bet is to spend your money and time trying to
acquire the very best-condition examples of disks you love and then learning
how to clean them properly (ie create a situation of more diamonds and fewer
turds). Then, invest in good playback gear, the right stylii and a preamp
with multiple EQ curves. Trying to undo wrecked records just never works.
