My experience is with the V1s.
If it puts some perspective, I chose to actually run S4 fronts, S2 rears and a sub.
There was something about the upper mids that was, to me, and in the store, better on the S2 and less good moving to the S4 and again to the S8. On the other hand, the low-end opened up with the S4. It opened a bit more with the S8 but... price being a factor: for me the smaller speakers with a sub worked better.
No idea on the V3s, but I would love to afford to find out.
