Lightning quick DYNAMIC amp in the under $1000 range

You would need signal into the amp for everything to cook properly. I would recommend some audible output on the amp. You can take a source directly into your amplifier and use the input level controls on the amp ( you have a tube pre, right ? ). Bypass the pre for this break in period. You might actually like it without the pre, as this would be a " passive " hook up. If you cannot do this, it will all just take longer. But as I mentioned to you earlier, if you listen every day, the amp will do you so much better, in sq, if left on all of the time. It is also possible to unplug your speakers, as many solid state power amps are ok without seeing the load of a speaker. I would ask Behringer, or a tech of some kind, if it would be ok. My 3 Yammie pro amps have no problem with this. Maybe someone else here will jump in at this juncture. Tube amps like to see a load.

bstat, anything to report ? or is it too soon ?

You know what, I've only put about 5-6 hours on the Waudio PC, but I do believe I hear an improvement in the bass - just seems a bit more meaty - long ways from total burn in, however. I will report back in a few weeks (as I do't think I can get away with constant playback -wife/kids great room gets used a LOT)
