From the Savant thread:
"I used to own a pair of N4C, which I sadly lost a few weeks ago. I then ordered the N4, the Savant, and the K10U from Noble to try them out. At first I did not like the Savant as much as the N4, noting the slight, slight difference in their brightness. (Don't take me wrong, Savant is 95% as bright as the N4, and it took me 20 mins to notice this slight difference.) But later one thing changed my mind: I noticed how much better the K10U was able to create an amazing sense of space, which N4 lacks. In the end I decided that I didn't like the heavy bass of K10U, which made the low notes of a piano sound like double-bass - it was too muddy for a instrumental fan like me. But I also discovered that I could not turn back to the N4 anymore, having experience the sense of space that K10 creates. This was when I realized the merit of Savant. It's between the N4 and the K10. It has both the clarity of the N4 and an improved sense of space (though not as great as K10). The slightly emphasized bass(compared to N4) revealed a not-insignificant portion of the bass line of some music pieces, which were undiscovered due to the absence of bass of the N4. This was the reason why in the end, I decided to keep the Savant, and I'm happy for the decision. "
