Welcome to the forum and to the Atlantic Technology thread.
Your receiver is a THX Select2 receiver. The 8200e system is a THX Ultra2 speaker system, while the 4400 System is a Select system. Either specification will provide full Dolby and THX Reference Level, but they are certified to do so in different sized spaces. The Ultra2 certification is for larger rooms, >3,000 cubic feet and viewing distances greater than 12', while Select certification is for smaller rooms of around 2,000 cubic feet, and shorter viewing distances:http://www.thx.com/consumer/home-ent...ce-categories/
So, the pertinent questions are: How big is your room, and; How loud do you like to listen? If you're in a large room and you want full Reference Level, (105 dB at the seats), you'll need the 8200e system, and then you'll likely want an outboard power amp to drive them. The 135 wpc of the 807 is good enough to push speakers to RL in a smaller room, but it will struggle in a larger room.
If your room is small to moderately sized and you don't want to listen at the ear-splitting levels of full RL, then the 4400 series speakers should work extremely well for you.
Another deciding factor is how much subwoofer you're interested in. If you want full RL from the speakers, you'll also need full RL from the subs. The LFE has a 10 dB boost, and the Bass Management system redirects all the bass from the main speakers to the sub. This raises the subwoofer SPL requirements to about 120 dB for full RL.
That kind of subwoofage is not cheap, and it usually involves some significant real estate in the room. If you are thinking of using just one sub, and you want to keep the subwoofer expenditure under about $500, then a Select2 speaker system will match up better with that level of subwoofage.
Atlantic Technology does not currently make an Ultra2 subwoofer system. In fact, in order to hit the Ultra2 specification, dual subs are required. There are other companies that make THX Ultra2 certified subwoofer systems:http://www.thx.com/consumer/home-ent...pe=&category=8
If you are going to get the 8200e system, I strongly recommend a subwoofer system capable of keeping up with the SPL capabilities of the speakers. I use 3 Seaton Sound Submersives in my system. I'm not suggesting you need to go that route, or spend that much. I'm just providing an example of what kind of subwoofer capability you need to match up well with the capabilities of the 8200e speakers.
AT does make a Select subwoofer system:http://www.atlantictechnology.com/default.asp?NodeId=51
This sub would work well in a small to moderate sized room, although there are many other subs that will work just as well, and are better "values", (IMO).
Good luck, and be sure to let us know what you decide.
