I just recently took a ride to the city and went to do some window shopping. I ended up in B&O shop and had a chance to demo Beolab 50 and Beolab 90 speakers. 50's sounded great but 90's were just awesome. The price for the 90's were about $100 000 USD a pair. This got me thinking how much bang for the buck they actually offer compared to the others? I tried to find a comparison of this price range speakers online but no luck. I also felt like most of the reviews I found about Beolab 90's were more or less biased. I would like to hear any neutral perspective about these particular speakers or similar ones from other brands. I am talking strictly about the sound, not design or other factors.
