Transparent? Yes, very much so. It does a remarkable job of showing the differences in recordings, even between different tracks on the same album. It's neither clinical, warm or overly coloured, but neither is it dry or antiseptic in its character. It's hard to describe but it manages to thread the needle between honesty and neutralness while not imparting an overt sound signature. There's always a sense of "rightness," a feeling of calm control no matter the situation. Now there are DACs out there with a stronger, more in-your-face character that emphasise detail or rhythm over everything else and while that can be exciting, at least at first blush, those DACs have tendency to impart that sound signature upon every recording, leading to an "editorialising" that breeds uniformity and takes away from the individual sound of the music played.
I found that with my Naim NDX that the La Scala replaced. It imposed its sonic character upon everything that I found robbed the music of personality over time, despite enjoying the sound in isolation.
The Aqua calls a spade a spade, and if the rest of your system isn't up to snuff or the recording poor, it'll tell you. But it never makes recordings unlistenable, even with many of my music being metal albums of questionable mixing, just tells you that there's good and bad out there.
Anyhoo, that's just my view. Give it a try if you can.
