Harman Kardon has upgraded their line of multi-room music speakers and they are now called Omni+. They all have 24Bit/192Khz HD audio, Spotify Connect, Chromecast built-in, Bluetooth and digital and analog input as well.

The previous version, Omni, lacked support for both Spotify Connect and Chromecast which made them almost unusable for most people. Now an Omni+ product, can re-broadcast Spotify Connect to first gen products.

The speakers are set up with the Harman Kardon controller app for iOS and Android.

OMNI 10+ fits small rooms and costs $249.95.

Omni 20+ is for larger rooms and costs $349.95.

Omni 50+ is portable and weatherproof, for use both indoors and outdoors. Has a rechargeable battery. Costs $499.95.

ADAPT+ connects to an existing system and lacks own speakers. Not released yet.
