Do you want to listen to them during break-in?
THE most efficient way to break in the amps is to put connect them to some VERY large load resistors, like 250 watts @ 8 ohms.
Feed the amps a wide bandwidth signal, like the FryKleaner offered by Jim Hagerman. Measure the output voltage and set the input level so you end up putting out about 8 watts continuous. Keep this up for at least a week if not two.
For something a bit less complicated, hook the amp up to a pair of speakers in a location other than your listening room. Point the speakers directly at each other with the front of the speakers almost touching. Wire up the speakers so that one amp channel to speaker is in-phase ( + to +, - to -). Wire the other amp channel to the other speaker with inverted phase (+ to -, - to +). Cover the speakers with some heavy blankets and play a wide range mono signal. Pink noise, or any of the various break-in tracks from Stereophile, etc.
This will get the job done quicker, but you would not be able to hear exactly what changes the amps go through.
It is sometimes a PITA but I think you will find the changes very educational.
Spirit, It was a pleasure to meet you at RMAF. I hope you have had most of your questions answered by listening to the various systems and talking to the different vendors.
