Check the output impedance of your source against prospective attenuators. From something I once read, I think there are ways to mismatch and lose the highs. Your might have better luck with a passive pre in between for impedance matching. (Schiit Sys $49)
Unless there is something else you don’t like about your DAC, it’s probably worth trying the low cost passive or attenuators first. Not sure where your current DAC lies on the spectrum of what’s available, but if you’re curious about a different sound there are a lot of choices, a lot of comparisons, and browsing is free.
