Are Receivers subject to Break-In Periods? I swear my Yamaha RX-A3050 sound better today than last week.

I have read thread after thread on subwoofers, for years in fact, I used to have a Mirage Omni S12 about four years ago. I liked it. But after using it for a few years (I bought it in 2005, sold it in 2008). It started to fatigue my ears, if that makes sense. At first I really liked it...

Did you guys know that we offer the best sounding sub-woofers that money can buy? We really do. And, we offer it to the DIY market so the customer can build it themselves and save hundreds of dollars. For a sealed box application you'll need one of our SW-12-04 woofers...

I just bought a new Denon 2808ci. It replaced a Denon 3805. While I like a lot of the new features of the 2808 the sound seems to be lacking. I've seen elsewhere mention of break-in periods for electronics. Do receivers have a break in time? I could see how one could theoretically "break-in"...
