I had the 6900 for 2 years and it is a wonderful sounding unit. I started with Monitor Audio RS6 and they sounded fantastic, then went to the Synchrony Ones and it sounded even better. The 6900 strained a little at the loudest levels ( I'm talking 3/4 on the volume control--big watts) but was magnificent at normal listening levels. I had the LED kit installed (got it from Audioclassics) to avoid bulb issues. If you like to hammer music at times, you might want to go bigger. If not, the MA is musically sublime.
