WAV files preferred
would prefer to NOT have MP3, MP4, WMA ie compressed files, tho I won't totally exclude them if there is no other choice.

It is possible to clean up recordings in some cases.(but we still can't make a silk purse....) Technological advances have given us some handy tools to tweak issues.

And yes we are also more aware of quality and audio levels (normalisation)

I don't think it would be in our interests to specialise, or theme the CDs. The variety of the previous set was IMHO a great assett to the series.
If it came to choosing between two artists, one of whom was on the first series and one not, then the newcomer would get my vote.
