yes I test Creative Inspire 7700 (7.1) and there is no comparison, the Logitech is 5x the power of creative (creative 90 watts rms, 505 watts rms logitech!), I use them for DVD and music creation and they are very good, very good reproduction of low frequencies.
Beware the subwoofer should be located 60 cm from the pc or tv cause waves magntiques!
I find the report correctly as they qualitprix intgrent a DTS and Pro Logic II
Yes I would do the same choice!
