They're quite different, with the Susvara excelling in transparency, separation, air, clarity, nice low end textures and a very lovely natural timbre and mid range. It has a very clean presentation and just this ease of delivery.
The VO delivery is less precise, less technical, but manages to present music in such a way that when listening with the VO, I find myself not analysing the music as much, or scrutinising the individual elements, but rather just kicking back, letting it flow and enjoying it as a whole. The VO sounds a lot thicker with music filling in all the gaps. Its bass is full on all the time with no lack of punch, and the top end is more rounded off than the Susvara.
