That's quite an endorsement of its realism and is much appreciated! I'd be curious to know what other DACs you've heard or your system details so we have a point of reference. Thanks for sharing your experience with us and enjoy it in the best of health! 
Well, I have had a few of the mid-range Audio-GD DAC's, the NuPrime DAC-9 and DAC-10, plus the internal DAC's in the IDA-8 and IDA-16 (I also have the MCX-4 and STA-9). You could say that NuPrime has a rather loyal customer here.
It's very hard to describe the effect, but it is simply way better than anything else I have listened to. The overriding theme is tone and realism for me. it is at odds with the visual cues....I see speakers, but they seem to have nothing to do with the music I am hearing. On many of the recordings I listened to, it no longer sounded like a very well done reproduction. I feel (at times) like I have snuck into the studio to sit in with the artists, and fortunately they don't see me so they can't call security to get rid of me.

I will now try to sell off most of the other NuPrime gear, and set my sights on the Evo Ones. I will probably keep the DAC-9 and the IDA-8 (for a small bedroom system) and sell off the rest. I can only imagine how the Evo Ones must sound if the DAC is this spectacular.
