I've often found that my enjoyment of a product is inversely correlated to how it measures (at least traditional measurements like THD and signal to noise). The only measurements that I've found to be at all meaningful in my evaluation of audio products are input and output impedance, and speaker waterfall charts.
The impedance numbers give some indication of likely compatibility between components. I'd never purchase a speaker based on its waterfall chart, but if there are obvious ringing or decay problems, I won't waste my time auditioning them because this does tend to correlate to my likely enjoyment of them.
