is it safe to plug the speaker into a ups (pure sinewave) or automatic voltage regulator?
Yes, you can plug the speaker to ups.

Hi Edifier, just want to ask, is M3300SF stop producing? Because I placed an order (with deposit) to a shop, but they told me that this model doesnt product anymore. Is this true? Quick and confirm reply (from anyone) is appreciated. I want to take back my deposit if this is true. Thanks.
M3300SF still available and we are running out stock at the moment, new batch will reach in 2 weeks time.

Eh, is there any bass or treble control for R501?
EDIT: Tempted to get Edifier DA5000 Pro...anyone know where can get it cheap in Penang Island?
EDIT 2:Edifier DA5000 PRO and Edifier C6XD...seems like I can get C6XD for a cheaper price...but is it good? I like C6XD's volume knob

but I like DA5000 Pro overall look

In terms of bass, treble and sound quality which is better?
Spec wise does say DA5000 Pro is better

Edifier already stop produce DA5000 pro. The replacement model will be DA5100 and it will available in 2 weeks time.
In term of SQ, personally i prefer DA5100 more than C6XD.
