May I ask what you are feeding your terminator?
Personally, I have found the source to be as important as the DAC. Now, if you don’t care for the tonality of your existing unit, that is not likely to change with a better source, but some of the other elements could very well. Then again, you might have this well sorted out already. As the Terminator is well regarded, and I have never heard it suggested that it’s deficient in any way, it may be that you just want a different flavor. Or it may be that you’ll benefit from feeding it a better source.
Of course, that does lead down a rabbit hole of sorts and you might end up searching for both devices and cabling, etc. For example - I had a nice DAC but upgraded from a souped up and optimized Mac mini to a dedicated streamer which yielded a nice improvement. I then went to a higher end streamer which again yielded nice benefits. That lead me to upgrade my DAC significantly, which didn’t yield as much improvement as I expected. At least not until I upgraded the USB cable. Then I changed the connection type (USB to stock Lightning Link “LL”). Then I upgraded the LL cable and incorporated some network filtering. All those changes yielded as much or more improvement than the original DAC upgrade. I’ve recently also added an upsampling processor so I’m still down my own rabbit hole but am ready to climb out. Attention to source and these small details has yielded a digital front end that is fully competitive with some state of the art systems in direct comparison.
If you still want some DACs to consider in that price range that are different than your Denafrips, I can suggest you consider auditioning the Simaudio 680, and the Auralic Vega G2.1.
Good luck,
