Also, I agree with Ralph that the tick and pops are indicative of album condition and tonearm tracking, not the medium.@minorl You may have missed my point- just checking; while the above is true, most ticks and pops are actually the result of poor RFI and overload margins of phono preamps. IOW I am saying that you can change out the phono preamp and thus rid yourself of a lot of ticks and pops.
The reasons why this is so are pretty technical- I can go into it if you like.
