Bang & Olufsen Beocreate 4 Amplifier
Vintage speakers can still sound good. Many even prefer their warmth. The Bang & Olufsen Beocreate 4 Amplifier lets you upgrade your old drivers for modern use. It combines a powerful four-channel amplifier, digital-to-analog converter, and digital signal processor on a single board designed to fit inside older B&O speakers. AirPlay, Bluetooth, and Spotify Connect are all supported, as is the Raspberry Pi for DSP customization.
