Well Alan, I'm not familiar with Nyquist's theorem but I would suggest that it is unlikely that it can be used to "prove" superiority, since in the area of hearing as opposed to scientifically measured frequency response etc., this is an entirely subjective judgement. I do seem to recall however that double blind testing showed no identifiable characteristic for either reproduction system which led to a consistent preference by the listeners.

Anyway enough of this.

I, like most of us I'm sure, have a lot of tapes which are getting past their sell by date and insist on self destructing in the middle of my favourite songs, so I am interested in transferring them to CD. You mentioned that you use "Cool Edit Pro" to clean up tracks, and I've had a look at their site. Did you get your copy locally or direct from the site? ie is it any cheaper at the local retail level in Oz? Secondly, you mention capturing the tracks in MP3 format, what software do you user to do this, is it still "Cool Edit"? I would be grateful for any info on the process and products you use. I imagine it would be of interest to everyone, but please contact me directly if you think that would be preferable.

Thanks
