There are a number of reasons as to why this is a major improvement, but the main ones are: Range dia Bluetooth has a range of around 10m. With Wi-Fi, the only range is your internet signal. If you get the internet at one side of your house / garden, you will be able to control this amplifier. Reliability and Connection - Wi-Fi is much more secure than Bluetooth so no unwanted connections can occur. Wi-Fi is also much more stable and is less likely to drop signal or break up like Bluetooth App Control dia This amplifier has its own (FREE) Phone / Tablet app that allows you to link your Spotify / Amazon Music / Apple Music / Digital Radio all through one simple app. No need for a separate remote. Simply hide the amp away and you can control everything without needing line of sight. App is Compatible with dia ANDROID dia and dia iOS. Multi-Room / Zoning The clever app allows you to set-up and control multiple amplifiers from a single device (app). This is perfect for multi-room / multi-zone applications where you would like to control the volume of each system separately / combine zones into 1, all from your phone / tablet. Depending on the level of music streaming service you use, you can also play different things in different zones at the same time and control all volumes separately. This is an incredibly versatile piece of kit and a fantastic alternative to dia SONOS.Power dia The amplifier may be small, but it packs a punch, at peak, this small unit will pump out an impressive 80W max @ 4OHM (2x 40W). However, thanks to the latest, CLASS-D DIGITAL sound reproduction technology, this little stereo amplifier sounds much louder than the figures suggest It really is impressive!
