There are 2 camps of thought, believers & non-believers in break-in. I'm a believer...

I usually subject any new audio gear to app. 100-200 hours of "stress". For your 1050, leave the tuner turned to a station that plays lots of dynamic music while you're at work or not home. Set it to some mode that drives all channels. Set the volume control to about 35-40. Leave it on 24 hours a day. Do this (with the speakers connected) for a couple of weeks. That should do it.

Most change usually happens in the first 20 hours. The preamp in my 1050 is not the quietest I've ever heard. It's driving a VERY quiet (Bryston 4B ST) amp which is connected to a pair of B&W Nautilus 804s. The major change I heard was less hiss from my speakers. BTW, before the 1050, I heard NO hiss from my speakers...
