New toy.
Being a cheap bastard, I do a fair amount of software synth. When I got my first Raspberry Pi, I tried my usual setup on it, just to see if it would work, and it kind of did. Tried it again more recently and found it was terrible, huge lag between hitting a key on the keyboard and getting sound. Plus the on-board audio isn't great in general, just 11-bit, and I wanted some improvement.
So I got this HiFiBerry DAC/sound card with XLR outputs and a case to fit it all in, and it's pretty sweet. Went with the XLR outputs so that I could hook it to my multitrack recorder without having to screw with random cables and adapters and crap. And now I can do soft-synth stuff without needing my music station to be near my computer desk. Very important now that I've upgraded to a 24-track recorder.
