I agree with you 100%. That Audio Refinement Complete integrated bench tested out poorly in someone elses review. It is sort of confirmed by the fact that YBA won't publish a 4 ohm rating (and a number of other stats) for the Complete, but they do publish all those stats for every other amp they make. But anyway, the Complete sure does sound pretty good for what it costs.
I can remember some reviews in HiFi Choice where one one component they'll said something like, "it sounds very good, but we can't explain why,". Then on another they will say: "It tested out very well, but we don't like how it sounds".
