How easily can you distinguish between different DACs?

I find it very easy to tell the difference between DACs and I am not some golden ear guy. But as you read in several replies, some can and some cannot tell the difference. Would save me a lot of money if I couldn’t, but I can. 

Been listening to a Qutest compared to my other generic entry DACs for a week now.  In very focused listening for a difference, yes, there is a tiny bit of detail in the Chord.    Detail over maybe not quite as smooth vocal sibilance or trumpet glare? $1600 worth?  There by remains the questions. 

Real test on how significant: If I walked out of the room and a DAC was swapped, or not, when I came back in could I tell which was which?  No.  Even when I am just sitting my chair listening for the sake of enjoying music and not digging for differences, I don't hear a difference. Those differences are ONLY on a very few of my CD's and only in fairly quick repeating of a short segment of music.  Older DTD, some newer ones.  That extra information is flat not there on say, Rubber Soul. Probably 90% of my music was recorded pre 1980. Quite a bit earlier.  If you were streaming DSD or some newly high end mastered high bitrate, there may be more of a difference.  Some folks seem to like very bright speakers, not me, so maybe there lies more differences.  So it depends. 

Funny some recordings.  I have a Stern/Ma recording and the cello moves around with the note.  But if you just sit back to enjoy the music, it sounds fine.  Message is, after I pick the end game, I am not going listening for flaws or differences, just listen to the music. 

The technology behind DAC is way more advanced than it was 10 years ago. You can get a DAC with a 120 dB signal to noise ratio no larger than a thumb drive. It is at the point were all dacs operating at the same rates do exactly the same thing, accurately crunch number. Any sonic difference is in the analog section and all sorts of Tomfoolery can be done there to produce a "house" sound. Personally, I do not want the house sound. I want THE sound without any pontification. 

@mijostyn  so you just choose the DAC that has the output stage built on the chip because it measures great, would you buy a preamp that uses an opamp output stage because it measures better than a discreet output stage?
