I have grown to like the mic idea. The font in #1 seems to fit best for me in this design. It helps maintain the overall feel. I like the font in #39 a lot, but the mic in the middle doesn't seem to match the font feel.
Just wanted to let you know that your design got a lot of praise and votes. From the the very beginning...clean, classic, mature and indicative of my business. Thank You, Brendan!
