I would disagree with the audio output side.  Aesthetically the BL8000s are excellent but I would personally prefer to listen to a pair of BL9s than a pair of BL8000s with a BL2.  Try them out - everyone has a personal opinion!

I have alreday listened to a pair of BL9 but they do not give so much bass and woofer efect than BL2. But otherwise sound better than BL8000, because of the lens.

I am also thinking about design of BL9 if this design suites BS 9000, here they dissapoint me very much as BL9 s are so small. The only part in aluminium by BL9 is the lens, this is not so beautiful than polished aluminimum housing of BL 8000.

The decision is very hard, as I would have to sell BL8000 with BL2 and pay another 4.000,-€ more just to have a pair of BL9s.

Would prefer BL5 but price for me is to high at this time.

BL9 is more hifi than Beolab8000s coupled with BL2. As you know the BL9s have more radiating surfaces ( drive unit area) to reproduce the bass region which really translates to better dynamics/ precision and lower distortion in the bass region than the BL2. Having more bass doesn't mean having better bass quality. Ask any audiophile and they will suggest that you get the Bl9s instead of the Bl2. You get more bang for your buck with the BL9s. For the BL9s you get a dedicated mid range unit which you don't get with the Beolab8000s and you also get more uniform sound dispersion characteristics. If you want to listen to a truer sound, go for the Bl9s but if you prefer more boom and tizz then maybe not. 

But I suggest you keep the Beolab 8000s and Beolab 2 for other purposes instead cos you are not getting their values worth. You were going to pay 4000 euros extra for the Beolab9s? That's crazy. 

you have a nother choise. Sell your BL8000, keep the BL2 and buy a pair of BL3.

The BL3 has a better sound in the top than a pair of BL9 and with your sub you also get a better buttom, more powerfull bass.

I had a setup like yours, but sold it at got me a pair of BL5 + 4*BL3. Have also lissent alot to BL9 but dident like the sound in the top or midrange, compared to BL3.

One of BL9 biggest flaw is the hight of the speaker. The lens is spreading the sound to the sides, not op and down, that means that when you stand or sit in a chair the speaker is way to low and you dont get the hole sound fraom the top. 

You dont have that problem with BL3, when you hang the speakers on the wall. But dont hang them under 1 meter over the floor.

I completely disliked the BL3 + BL2 combo. The BL2 couldn't keep up with vaguely fast electronic music. The BL3s - for audio playback - are way better on their own.

However, if you're only going to use this combo for movies (BL3/BL2), it's far more effective.
