1,000 hours? (6 weeks)
2,000 hours? (3 months)
That has to be a new record with audio gear.
Used to be 50 to 300 hours was plenty.
I'll have another listen to the XR45 sometime when the snow thaws I guess. Report to follow.

I have an amp that I bought in 1993 - I wont tell you the name. But it is still breaking in. I dont want to tell you how it sounds because it wouldn't be fair.
Forever hopeful

- NAD 3020 right??? - longtimequadowner 18:56:32 01/03/04 (1)
  Do I get partial points for guessing NAD even if not the correct model number????
  Just kidding, try not to take it seriously. Your posts are abundantly clear - so I based my guess on that, and a model number circa 1993 - could be wrong on the production dates though...
  NAD is a fabulous brand, and the 3020 a clear classic by all acounts - but an open mind is priceless.
  - The 3020 was introduced in the late 70's... (nt) - DeKay 23:45:52 01/03/04 (0)

I'm only relating my direct experience, with a component I've had in my home for 8 weeks now - but aging takes a long time, longer than hours or even hundreds of hours (after all only 10 days is 240 hours already - Paul on the PS Audio power forum says even his Xtream Statements take 2 weeks minimum, just for power wire transmission!).
I listen to the panasonic anywhere from 3 to 5 hours per day, and since I'm listening to an all digital cablefeed, I am hearing largely new music that I have no preconceptions about. Still, you hear the songs in heaviest rotation at least once daily, enough to appreciate the differences over time.
I'm not suggesting the Panasonic will then overtake stereophile rated class A components, but in my personal experience (and I posted them on this page at those times/dates) there was an easily perceptible change in overall dimensionality, focus, and musicality - easily in some of the areas you mentioned it was weaker aka "air and ambiance". I'm not doubting your conclusions for a minute, and am not questioning them since I have no direct experience with the other equipment you mention.
I know many feel breakin is a joke and cop-out, but if you ever listen to a new component from day one with no other tweaks, component changes, speaker movements, interconnect changes, etc - it's really not that hard to hear. Not daily, but weekly for sure. How many people on this page go for 6 whole months without changing a single thing? Sometimes I wonder...
