V25 vs 300 Soundtouch

[VdaSilva]

my parents own the v25 lifestyle and now want to buy the 300 soundtouch, is the sound and the function better?

I'm not sure I would make the switch unless something was wrong with the V25 or you wanted to get rid of some wires.  I have a Bose 300 with rear surrounds and bass module that I like very much, but I doubt it sounds any better than what your parents already have.
