Look into Blackgate capcitors. This is something I have saved. I have Blckgate caps in my Denon 5910 plus other little goodies. The unit sounded great at 500 hours and it was not done cooking. 1000 hours and another blanket was lifted from the speakers. I am sure equipment varies in break in period but It happens and it can happen in a big way.
It can take many hundreds of hours before the maximum sonic benefits can be heard in audio circuits that use Black Gates. This long settling-in procedure is often a controversial issue when auditioning such equipment, as the frequency responses will tend to shift around greatly during this period - making the equipment sound different from one audition to another. Once completely 'burnt-in' however, the benefits can be heard clearly.
