I think measurements give you important information about a product that complements use and listening experiences. For loudspeakers, especially, knowing the actual performance parameters can tell you a lot about how you might react to the product over time. For example, a big mid-bass bump, or being a little too hot in the upper frequencies, might produce an exciting demo, but then later on you're finding the technicolor presentation a little tiring, and it might be difficult to correct the perceived problems with conventional means (like room treatment, placement, or equalization).
Even for electronics I appreciate measurements. I like to see really low SNRs, pristine distortion plots, and, for amplifiers, some evidence of what their power output characteristics are into varying loads. All of this stuff tells you so much more than a singular THD number or a simple watts per channel rating.
Personally, I think the Audioholics reviews are shaping up very nicely. And you still need trained interpretation of the results, because as anyone that produces measurements and metrics for almost any field knows, you've got to know something about how the measurements were generated, what was really measured in context, and how they describe (or really don't describe) the big picture. The poster child for this need for interpretation was the recent Velodyne DD18+ review. The measurements were revealing, but it was clear you needed to know what you were looking at.
