Notwithstanding my respect for @yyzsantabarbara I disagree and find the Musetec 005 neutral, though I agree with slightly smooth. In that regard it is unlike the conventional wisdom of DACs using an ESS chip. It is, though, very revealing of the details inside the music for it resolves low level detail really well. It is, as we always say, very dependent on the designer implementation and on the system in which it is used. I use it with a Rogue tube system.
For some agreement on the neutrality see this, a review comparing it to the Holo May.
