Scary thought that peaple can be so easily misled, what kind of a world do we live in when people start comparing Chip amps to solid state and tube stuff, I have been installing Gear for many years and those multi-room B&O systems were nothing but underpowered and can't drive any kind of a load peices of junk, present one of them with a 4Ohm load and see what happens. And I wouldn't give that much credit to those guy's that write the reviews, I have had experiences with those guy's too and well, they arn't all that. Let you ears do the decission making, High current and Low impedence is the way to go baby!!!
