I used a crown cm11 mike with a shure reciever.A wonderful mike[same one Garth Brooks uses].Also used by Cher on her farewell tour.I was very happy with it unless I was doing a big ballad that needed lots of vocal dynamics and mike technique.It kind of defeated the pupose of hands free when I had to physically move the mike away from my mouth when attacking high notes. There are probably better set ups with some of the high end sennheisers etc. But most people consider the cm11 the industry standard for the price. Terry
