Denon launched their HEOS multi-room audio system in 2014. Originally, the line consisted of only three speaker models and a WiFi extender, however the line has grown to include a sound bar and preamp among other items. Today, Denon’s proved that they have a few more tricks up their sleeves.


HEOS will now support Hi-Res audio. The updated line which is being called HS2 by Denon, supports Hi-Resolution audio delivered via your network or a USB drive. WAV (PCM), Apple Lossless Audio, and FLAC files at up to 24-bit/192kHz quality are all supported. AIFF (Audio Interchange File Format) will be coming soon with a future update.


The hardware for the HS2 line will also get a refresh. Bluetooth will come built-in to the speakers. The internals of the system also features an ARM A9 1.25 GHz Processor with 512 MB of flash memory and 256 MB of RAM. Denon says that the speakers of the new HS2 line are backward compatible with older HEOS speakers and can easily be added to an existing HEOS ecosystem.


The HEOS speakers are controlled by an app which is compatible with Android, iOS and Fire devices. When HEOS first launched, its streaming options were limited. However, a variety of streaming services are now available such as Spotify®, Pandora®, TuneIn, Rhapsody™, iHeart Radio, TIDAL, SiriusXM, Soundcloud® and Amazon Music.


Denon’s HS2 line should begin arriving at authorized retailers such as Amazon soon. More information can also be found on Denon’s web site.
