Speaker manufacturer Denon announced a refresh of its HEOS wireless speaker line this week, adding Bluetooth functionality to the entire line, as well as support for various hi-res audio files. The new line, designated Series 2, ranges in price from $200 to $600 and is available for purchase now.
The HEOS speakers are similar to Sonos in that they are Wi-Fi connected and controlled by a proprietary app. Owners of the Series 1 line won't be able to get the new features unless they add a Series 2 speaker to their system or use a Bluetooth dongle. The hi-res file types supported by the new speakers include uncompressed WAV (PCM), ALAC (Apple Lossless Audio Codec), and FLAC (Free Lossless Audio Codec). Support for DSD and AIFF files is expected to arrive in the near future. Unfortunately, it doesn't look like Denon's system will ever get Google Cast support, despite earlier plans to do so.
