I agree. The DAC is one part of the audio chain, a chain in which a parts need to not only be of high quality, but work well with each other.
Connect a terrific super ultra clear, made by virgins, designed by God, DAC to a mediocre preamp, the end result is mediocre audio. Connected the same DAC to a ****ty preamp, ****ty audio.
Take not too bad DAC (bur considerably worse than the one above), connect it to a well equalized decent preamp (optimized for the DAC), you'll get pretty good audio that people are likely to praise and desire.
I'm simply illustrating, as you did, that obsessing over the DAC alone may lead you down the wrong path.
And don't get me started on the effect RAM and a CPU (don't) have on audio quality.
