can i know why r u saying that the users of these speakers r really happy with them if u check the comments.
I auditioned Sony SRS-D5 & D8 at sony showroom some months back.
The bass is not satisfactory, highs aren't crisp, overall the SQ is poor for what u pay.. And about the reviews, they might never had a chance to listen to other speakers in the same price range.
The creative inspire T3100 - 2K has better SQ & some punchy bass than D5..
About the T6160, - 3.4k in local market.. They lack highs, which are better in T6100 - 3.5K
Can't comment on the philips SPA 5300 haven't auditioned them..
