Granted the Imperial Bar is not cheap, but it performs its service 1A. The Pair devices run smoothly and the devices are coupled to first always recognized. The sound comes (digital) in top quality on my system, and also the range is depending on the device used, good to very good, is 6-10m depending on the partition walls are loose inside. Functionally, in the Imperial Bar so everything TipTop!
One shortcoming there are unfortunately still what in the price leads to a star deduction. There is no power switch, ie the Imperial Bar is as soon as you plugged into the outlet, permanently turned on and search for devices. I now Bypass this disadvantage by a radio-controlled socket that has once tasted a few extra Euros.
