Hi Chctap,
For active speakers, most of the brands are coming from pro audio industry, but there are some made HiFi brands make for home theatre that you can also use for HiFi listening. Some of the brands you can consider are
Adam Audio
Eve Audio
Yamaha
Mackie
KRK
ATC
KEF
Focal Audio
PMC
What kind of budget range you have in mind?
I believe you can get most bookshelf under $1k, but the better one usually cost much more. Floorstander will be even higher.
