I have Alien Ears. I have a 5-driver set (3 low, 1 mid, 1 high). They are fantastic. So good I ordered anther 8 driver set (4 low, 2 mid, 2 high). Can't really tell the difference. So, I primarily use the 5 driver set and keep the 8 as backup. The best part is no hauling around amps. I do have a Gator rack with my 2 wireless units and a Furman in. I'm using a QuadCortex to feed FOH. Amp sim, Parametrix, Compressor, noise gate. As well as a completely dry channel. My sound has never been better. I do miss my amps sometimes.
