Thanks, I had wondered about doing the RIAA filter in DSP . . . It will be interesting to see how they have factored in cartridge loading and how adjustable this is.

Currently I am using a home built Phono preamp that I have disabled the riaa filters in.(quite a simple procedure..I'll look for and paste the link to the DIYAudio thread)
This gives me simple gain to line level and the ability to adjust for cartridge loading.

Having the files recorded without riaa compensation I then run them through the declicker which seems to do a much better find and kill process than if the files were flat response.

Also worth trying....
(and despite this being primarily for speech it works very well on music..and is free)
