Another problem with Actives is that if anything malfunctions, you have to send to the entire unit back for repairs. With repair/replacement times in India, I've seen it extend to 2-3 months for even high selling brands such as Q Acoustics. I shudder with KEF, especially a higher end unit.
Unless you've got a spare system, you'll out of luck (and music) for an extended period of time. Much easier to get/have a spare pair of speakers/amp for a passive system if something fails.
The problem with most people when they go for actives is that they don't exactly think through the benifits/disadvantages of active vs passive and many a time, they labour under certain delusions.
The biggest delusion/misunderstanding that most people have with respect to Active Speakers is that cables are a non-issue and it's easier to get a tidier and less cluttered setup.
Nothing could be farther from the truth. It's much harder to get cabling to look tidy in an active setup, Especially if you want to do more than just wireless streaming.
Plug an optical cable/hdmi/USB to the back of a KEF LS50II or Q M20 HD and you've got cable clutter that's much more difficult to manage compared to speaker cables.
The least cluttered active option is to go with one that is similar to a passive one i.e. those that come with a central hub (such as Buchardt A500 and the Mission LX-2 connect).
