[quote user="Chrisreunion"]When you go & visit each B&O shop after landing in a new city, does that make you obsessed? [/quote] I'm asking myself same question.... Actually, my wife asking herself same question over and over again

[quote user="Style"]The main benefit of class D is effiency. AB is soundwise equivalent and even better when it comes to high frequencies.[/quote] hm ... Does it mean that class D mid's and high's in to BL5 are there for "purely marketing" reason ? Or it is not "audiophile correct" to sell 18K speakers D+AB ?

[quote user="henrik"]And possibly also a matter of prestige in using their own ICE-technology in their TOTL speaker?[/quote] Interesting point ... I'm not that technically educated, but can you go digital with mixed amplifiers ? D+AB BL5 are all D and they have digital input.

[quote user="tournedos"]Therefore, using class D for the higher frequencies as well would add a lot of cost and technical difficulties with practically no benefits.[/quote] Interesting, what about 5's then ? Is there any down sides with this setting D+AB ?

Does anybody know why they used class D for bass and AB for mid and treble ?
