You have come to the point of recognizing that what measures well doesn't ensure sounding well. Conversely sounding well doesn't necessarily correlate with measuring well. IMHO listeners are in the long run much better off choosing audio components that sound best to 'their own ears. It doesn't matter what others may think or hear differently than you. It's purely subjective. Just be happy and select what you determine to be the better sounding more satisfying component.
As this thread has clearly demonstrated people are simply going to disagree on how a particular audio component sounds. Some posters here find Benchmark to sound excellent and others aren't impressed with them by any measure. In my own encounters with this brand's products they struck me as clinical/analytical/sterile. If you find the P.S,Audio DAC more enjoyable and engaging, trust your own ears. I wouldn't obsess over the measurements at all.
