Despite an excellent sound I have returned the device with a heavy heart again. The designer should sometimes ask how I think such, not exactly cheap Appliance clean, it would not be a problem, you could unscrew the upper part and clean. Possessions seen the Aura from a dealer, after a year covered in dust from inside and outside totally scratched. As well as the most amazing sound is no longer fun. Property me then for the corresponding Onyx eliminated. I would not recommend this unit unfortunately.
