Sound on Sound is an excellent resource - they also have a great archive of articles on-line that non-subscribers can read. They do tend to be pretty high end, so it's mostly not written at newbie level, but if you're prepared to put some time into it the information is very good.
Audio Technology is also very good. In fact I just subscribed to it after buying 3 or 4 issues. What's appealing so far is that it has a comfortable balance of content. I'm not experienced enough to want to wade through something that's just solid tech-speak from cover to cover, but AT has plenty of articles and interviews with the people who actually use the gear - both artists and engineers. So you get not just the technical stuff, but info on how it's used. Good tutorials in the mag too.
