I did not buy this unit as mentioned in my review. It was a review unit provided by Edifier

I'm not too sure about the exact price but it's around RM2000+ and you can get it at lowyat sri com or all it if I'm not mistaken. Usually the new Edifiers are always there

I really appreciate the answer. Can I get in touch with someone from Edifier that can answer me via email? In my country (Italy) there's no Edifier Multimedia dealer so I've bought it via Amazon Marketplace (external seller from Poland which uses Amazon as a store). For warranty claim I need to send the system through international shipment. Prior to spending a lot of money for shipment (due to high volume/weight) and have in return "the same system" (new but that works in the same way), I would like to know if the S760D, by design, have the bass-management as I explained above (reading the OP review, I would say that it is a design problem since he's confirming the same results with another unit). I can send a lot of "test files" which can clearly shows where's the problem. I really would like to fix this (for me but also for Edifier). The system, when working correctly, is really good but actually has so many flaws that it is almost not "usable" for some serious work/listening. All the similar systems from Logitech or other brands are almost "toys" (but have bass-management working as expected) so Edifier is the only choice available for a pc environment (excluding higher priced studio monitors).
Thanks.

Another week... another no-response.
The only PM I've received here is from another user who is suffering the same problems... I'm just starting to think that it is Edifier (the company) itself who don't want to have a debate at all.
