GRACE AUDIO Bluetooth Digital Stereo Amplifier
Grace Digital's GDI-BTAR502 100 Watt Digital Integrated Stereo Amplifier is a nice, compact bluetooth amplifier with flexibility in how it can be used. It is not as incredibly powerful as some people are characterizing it. It's 50w x 2 into 6 ohms. As a point of comparison, my self-powered speakers that I use for my Mobile DJ business, Electro Voice ELX112P, have a 1000 w Class D amplifier built into them.
