There is always "different" but "better" is harder to come by. :)
What is it you are missing? Is your imaging, sound stage what you want? Do you care about air and space around notes of more intimate music?
It’s a great thing to be happy with what you have. Don’t underestimate it.
Now, about more weed. Modern weed is stronger, with more THC, but also has more tar and nicotine in it. Just because it's missing all the crap they put into commercial cigarettes doesn't mean it's safe to smoke. Any time you burn things and inhale you are risking your lungs. I'm also not calling it the demon weed, just suggesting caution. A new dac would not cause lung cancer, or leave you in danger of driving or operating heavy machinery for days afterwards. Now that I think about it, yes, you are safer buying a new DAC. :)
Best,
