I still subscribe and read UHF. The entire principle of having a dedicated listening room as reference is an idea I like. The panel of three listers giving a review on the same product makes sense as well. They provide measurements as well.
My ONLY knock on them is because they're so small, and only 3 reviewers, they don't move through alot of manufactures. They tend to review one company's peice, and the same brand shows up for months. I remember one year it seemed like all they ever reviewed was Copland. Lately they've reviewed a ton of stuff from China. Not my cup of tea, but they still teach principles to users.
The latest issue has a great article on Digital Interconnects and why they can sound different. Very few magazines actually teach anymore, they have to devote most of their pages and time to advertising (Factory tours, panel discussions from CEO's or marketing heads) UHF is still small enough they don't have to do this. Heck they still print in black and white!
