Sound on Sound totally sucks! My wife picked up a copy last week, and she said: "What's that? A product catalog?". She was right on: nothing but plain boring gear review. No journalism what so ever. There's absolutly nothing to learn from that magazine (except specs of gear), and its very pricy in the US.
I actually enjoy reading EQ a lot lately, and I've even subscribed ($14/year only). Its a nice mix between interviews & featuring artists and how they made an album.
Tape Op is interesting & fun to read, but the style of journalism is very amateurish IMHO. I'm also rather upset that I have to spend $4.- for each issue coz they NEVER add my name to the list of subscribers, no matter how many emails I drop them! *grrrrrrrrr*
MIX is way too much "gossip". I'm not interested at all who was appointed the new CEO or XYZ Studios, and I never got interested in the obituaries either. Its also a lot of info on "live sound" which for me, as a semi-studio owner, is not interesting.
