I just hooked up my Phillips CD recorder to my stereo to duplicate the vinyls and it works correctly. I do not use special filters. I do have special digital cables when recording Cds, though , but for analog (Vinyls) recordings they are the good old quality cables I always had!
I am happy with the results and it does not fade away as taping vinyls on cassettes , however good the brand (Maxxell XL II-s) was my fave until I switched to Cd-Rs.
The sound difference is noticeable : on some compilations I make, there are Cd track and then Vinyl tracks and there are scratches and pops but who cares.... nothing shocking
I do not trust computers in transferring analog to digital or even digital to digital! Many copies of cd-Rs from friends have problems playing in most decks. I never have the problem as I use the Hi-fi option.
