Aesthetics and Portability

It’s a little thing, and it looks like a piece of artillery. Shiny and boxy with a hint of je ne sais quoi. Using the Bluetooth function, you can easily keep it in your pocket. Just watch out for the volume knob; an unfortunate movement near your jean pocket can blast your ears into oblivion.

SOUND – iFi xDSD Hi-Res Bluetooth Portable USB DAC Review 

Thumbs up on this one. You’re not going to get much color out of the xDSD. Rather, it just enhances the sound you already have. Perhaps it widens the soundstage a bit. But in general, it’s just optimizing your existing mix. The bass boost is subtle, but definitely noticeable, especially listening to pop music with deep bass. The 3D function introduces a little refinement and spaciousness to the music. It crystallizes the sound nicely, taking a little bit of muddiness out of the mix. The differences between the 2 filters (“measure” and “listen”) are slight, but “measure” enhances the frequency a little. High cymbals, for example, come out a tad clearer and crisper.  The “listen” mode improves the transient response, giving your music that extra sense of snap. iFi did a fantastic job here.

And how does Bluetooth sound? To be honest, it’s hard to compare the wired and wireless connection because it takes too long to switch between the two. But the fact that I can’t tell is a good sign.
