It's that time of year. In less than two weeks I'll be en route to Schaumburg IL for the Audio Expo North America (AXPONA). Due to the growth in exhibitors, they have moved the expo to the Renaissance Schaumburg Convention Center. In addition to seminars, they have added "master classes" to display a few new products, plus there are live music events Friday and Saturday night. I'll post a few highlights each day, time permitting.
