What it means to be from Boston
First and foremost, Boston is an engineering company,
and every Boston system is optimized to meet the highest
performance standards (our own). Of course, performance
is only one measure of value. So we’re careful to build all our
products with strict attention to everything from the choice
of materials to the details of t and nish. It’s how we’ve
been exceeding the expectations of serious listeners for
more than thirty years.
