Balance v BL9s

I like the functionality of the Mozart platform so much I am considering replacing a pair of BL9s with a Balance. I know that sounds strange. The 9s are in my bedroom connected to a V1. Being in my bedroom they are used at low volume levels. Any comments on the sound quality of a Balance compared to 9s at low volume levels? Would I be losing a lot of sound quality? I ask this as someone who likes my 28s much better than the 50s I had previously.

Thanks!

Maybe my reading comprehension is failing, but I thought the conclusion of the recent thread (Mozart speakers in stereo with Line input - (beoworld.org) was they don't work well for TV applications (without an AppleTV) because the line-in introduces a non-configurable audio delay.  Note that this is not a problem with the BL28s because they have a PL socket, but the Balance does not.

No, my question was poorly worded. I use the 9s with the V1, but only with the V1 as a music source. Because of the relative positions in the room of the V1 and the 9s, when watching TV I use only the V1’s built in speaker. The Balance would also be used only for music, not with the TV.
