Looking for a simple, affordable entrée to the world of streaming music? Bremen delivers! Compact, feature-rich and easy to use, Bremen might be bargain-priced but make no mistake: it offers High-End audiophile performance. Like Silent Angel’s upmarket Munich Series, B1’s hardware and software were designed without compromise, for sound quality that will amaze serious music lovers.
