If you are constrained for space (as is my case), I think you should consider the A2 above the A5s.
I've not personally listened to the A5s so I can't comment on how better they sound, but all the reviews I've read say that the A5s are pretty good. The A2s themselves sound pretty good except for an occasionally annoying midbass hump. This is not an issue with movies at all.
If you are thinking of A5s and you do have enough space, you can also think of a pair of entry-level Wharfedales (9.2?) + Norge 2060 combo. These will cost just a bit extra, but would sound a bit better (esp. for music). But then you'll have to manage two units (speakers & amp).
The A2s and A5s are active, so the amp is built in -- lesser components to place/manage. I think the Edifiers also have a built-in amp.
The A2s and A5s are magnetically shielded. You can place them right next to the TV or magnetically sensitive devices with no issues. And yep, they work right out of the box. I got only a pair of EP to EP cables with the A2s, so you will need to buy an EP to RCA (pair) cable or an RCA (pair) to RCA (pair) cable separately to connect them to the TV.
As I just mentioned, in the case of the A2s, you can connect them to the TV with either an EP to RCA (pair) cable or with a RCA (pair) to RCA (pair) cable. The A2s have two inputs -- EP socket and RCA pair. If your TV has variable outs you can control the volume from the TV's remote, or if your TV has fixed outs, you'll have to control the volume through the A2s.
The A5s, and especially the A2s, are best when they are at ear level (when you are in your viewing/listening) position. So you might need to place them on stands to elevate them, depending on whether you have space on your TV rack.
I'll confuse you a bit more

and give you one more option at 10K:
M-Audio Studiophile AV40 20W + 20W Powered Reference Monitors -
These (the M-Audio AV40s) are also supposed to be pretty good, and some people prefer these over the A2. I haven't listened to them personally but I think Thad E Ginathom uses these.
