Unique for sure.
If you have other DAC that sounds cold as ice (which doesn't mean "sibilant" or "treble-forward"), there may be a similar effect, but I don't have such DACs.
I strongly suggest every Pro 82 and E06 owner to invest 9$ in EL-D01, even if you have to skip your morning cappuccino for that.
Any special hints on sellers you recommend buying from or avoiding?
The price is right on this one ( $9.02 ), and from an eBay seller with a high rating:

But this one is about $5 more ( $13.93 ) but notes an "ELNA capacitor" (that means nothing to me but I suppose it's a differentiator?)
