Dear pro,

Im in a dilemma at the moment on which to choose between Edifier S760D, Edifier S550 or Logitech Z906 (I have a c3 at home at the moment) (price is not a major factor).

I don't have a chance to listen to Edifier S760D. One of the salesman at lowyat told me that basically the S760D and S550 sounds the same. The only difference is only the Dolby Pro Logic II and DTS. Without these two they would sound the same. Is this right or just some wrong fact being thrown at me?

As to my knowledge, Edifier produces better quality sounds and have more details and separation but less bass, whereas Logitech produces higher pitch and bigger bass.
I watch movie more than i listen to music. so which is better for me?
Will Edifier S760D produces bigger/smaller or the same bass (solid) than logitech z906? 
Logitech having 500RMS while Edifier having 540RMS.
I didn't have the chance to listen to both edifier properly as the demo units they have are faulty.

Any help is appreciated.

Thank you.
Cheers

Thx everyone for the tips.

Have anyone of you heard the actual set? Is the S760D bass comparable or superior to the Z906?
