I'm sorry, but if I'm spending £2,000+ on a speaker system, it would not be on a B&O speaker system. It's flat, dull and lifeless. And spending £8,000 or so on their top of the range speaker is just silly. You really cannot compare B&O with proper audiophile equipment.
The idea of these "one trick ponies" as you put them is to provide the ultimate in sound quality - not to put your discs in the right place or percolate your coffee. You simply cannot pitch a B&O system alongside a well-research and expertly picked audiophile system - it'd lose on almost every count!
You haven't listened to the B&O systems I'm talking about. The top B&O speakers are £11.5k, and sound like they should cost far more.
You simply can pitch a B&O system alongside a well-researched and expertly picked audiophile system. A lot of B&O systems would yes, but BeoLab 9s or BeoLab 5s alongside a BeoSound 9000 or BeoSound 4 would give any other kit serious issues when it comes to 'sound per pound'.
B&O have had bit of a turn-around. Their older speakers, such as the BeoLab 6000s can be easily outperformed by speakers of the same price from other manufacturers (although they are kinda remarkable for their size). However, since 2001 when the BeoLab 5s came out, and earlier this year when the BeoLab 9s came out, things have changed a lot. Sad thing is, people are still viewing B&O with the same frame of mind they would have years ago.
Before you judge B&O any further, have a listen to some correctly set up (I cannot emphasize this enough) BeoLab 5s or BeoLab 9s. You will be very pleasantly surprised.
