Beo;
Two different components. One quite mobile, one more stationary. Both very enjoyable.
The Beosound 1 is a single unit of 5 speakers, and can be moved around relatively easy. Left, Right, angled, 3 metres over, outside, etc. There are optional wall mounts, a metal stand on a single leg, and a swivel-mounted metal cabinet, open at either side for CDs.
I can place my BS1 next to a TV, and then below the TV, and there is different sound quality. You can unplug it and take it in the next room, terrace, garden, or to a neighbor's house. Very good sound ( FM Radio, CD, MP3, TV ) all from one unit.
Using the AUX cable attachment at the bottom of the BS1, it will accept an MP3 player, or the stereo sound from a TV or SAT box, as a quick Home Theatre unit. . The BS1 is slightly angled, so the sound is best at ear level as Tom mentioned, or angled to be facing up towards the listener. I can place mine out on a table, and then against a solid wall, and there is a difference in the sound of the music. It's fun to play around with this way, as I'm sure it was designed to be.
The BL 4000 are single speakers only, well amplified, and not designed to be moved around in the manner the BS1 is. The speakers come with wall mounts in the box, and as mentioned previously there are metals stands (similar to the BS1 stand ), and small plastic table stands as options. Better sound quality I think.
When I bought mine, I tried all the options at home first before deciding. This is one benefit of having a good relationship with a B&O store and staff. The metal stands looked good, but didn't work for me: Interested guests, kids, etc. led to the possibility of one or both being knocked over. The wall mounts did not stop the ingenuity of the kids getting up to them, using a chair or climbing up the Plasma. When you place them too high up the wall, you lose the sound quality ( at ear level ) Tom has mentioned. It depends on your household.
I chose to place each speaker on a solid surface, each on either side of a Plasma. About a month later, I went back for the small plastic stands, as the sound angle seems to me to be slightly enhanced this way in the living room. They remain placed this way.
So, as an possible action plan, I would suggest that you consider starting out with a BS 1. Many of us did. The unit can be moved about, sounds great, and the AUX connection has a many applications today. Then consider adding to your AV system , or collection if you will, and move up the ladder as you like.
I wouldn't reccommend that you wait for the " Ultimate System " from Struer, as it suggests some finite termination, and really doesn't exist. The designs from Struer will keep coming down the Danish expressway, and will continue to do so, evolving as demand, creativity, and technology allow.
Like Skiing, if you wait for the " perfect powder " to hit the slopes, another year will go by.
