I both bought the Spirit and this smaller unit here. I phantom powered them with a Vovox unshielded premium cable and first thing I noticed that this one is not capable of suppressing the hum introduced by an unshielded cable (whereas the bigger one greatly does). Obviously, with a normal XLR this problem doesn't apply.
Secondly, This unit's noise fairly low but a bit too crispy on the very high spectrum, where the bigger brother has instead a really low, browny noise, basically inaudible while you record your signal, you can always hear it on this unit here instead.
Last, sound quality is really OK but... there's no comparison with bigger brother Spirit: at 100 more bucks, you get a wider and natural sound, with great Neumann-like dynamics and spectrum clarity, things that you're not gonna find on this mangled little brother.
My advice: bank on the Spirit, it really does worth the price, more than this unit would possibly ever do.
