Sound on Sound magazine. Not only do they give reviews, but there are interviews with pro engineers, tutorial on DAW's, Q&A, and tips on improving recordings....people send CD's of ther recordings. SOS listens to them and then give advise on how to improve them. WE are able to hear the before and after on line. Also have DVD's quarterly that have cool things like going to Rode in Australia and seeing how they make thier mikes, so going to a project studio and showing the before and after.
