I had since now Beovox/Beolab Penta, BL 4,Bl 3, Beolab2000, BL 2, Beovox 3000, BL 8000, BL 6000, BL 4000, BL 1 and BL 5.
Beolab 5 was sold last week! Lab 3 last month!
I decided to keep only my beloved BL 1 and BL 4000(all black). I really love the design and the sound. The black color is really stunning.
IMHO BL 6000 does not worth it. BL 8000 could be a solution for you, however you have to listen this speaker: you may find that it sounds metallic.
So, go for BL1. It is IMHO the most beautiful speaker made by B&O. It does not sound like BL5, but it is not far for it.
Just my 2 c.
