Yes. At least I haven't heard of any audio gear that won't produce sound until you calibrate it. (And I doubt the 950 is the first pre-pro to start doing something that unusual.) I'm at a loss as to why you're getting no sound.

Meanwhile, any chance you can give us a mental snapshot of your system: i.e., what's hooked up to your 950, how the 950 is hooked up to the amp and how the amp is hooked up to your speakers?

Thanx,
