Looking for a DAC that's better than Mc C47

Hi guys, I'm looking for a DAC upgrade to improve my current setup.  Using the Mcintosh C47 digital preamp as the main interface source for a few years.

I find the C47 lacking in rich harmonics tones and 3D-ness in digital music playback.  Budget around USD1000. 

I've heard Denafrips Aries II and it doesn't even sound close.  Topping, SMSL & Gustard around this price also not close.  The C47 is good sounding already, just wanting to better it.

Any recommendations?  Thank you.
