One of the things I neglected to explain is that I rejected online resampling, not only because it is difficult to ascertain which resampler to use and because it adds processing load etc. It is because I can make poorly mastered audio files sound much better for the music that I want for keeps.
Attached is the FFT analysis of a bad sounding file where there is evident hardness in the treble. Repeated FFT plots using the cursor show that the large spike just below the sampling frequency is always there, due to faulty mastering. The large excursion from the 'sound' floor is likely to cause intermodulation distortion on playback. By using a FFT filter and removing this very narrow band spike, SQ can be improved markedly. One particular brand of CDs contains large hf double spikes on much of the material I have analysed and it is not surprising that these do not sound good in the treble.
The resampling process takes time but it is the quality FFT analyser and the large number of filters in Audition 3 that score for me.
I mainly use a high sampling frequency high roll off filter for playback as none of the filters on boxes that I have sound permanently best, and it is very distracting to be changing filters as playback progresses from file to file.
