Curt, I got the repaired amps hooked up today. I've been trying to burn them in pushing them medium playing...just like you said. Well, I couldn't push them hard. I turned the music up until it was hitting 108db peaks. So, I guess pushing them medium will have to do
I've had them up there for about 7 hours now 
Glad ta have'em back!
thanks so much for the great service!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!+1more!
ps...I've been in the basement cleaning 
See I told you we would get you back up quickly. Happy to hear everything is back to normal. That is if 108dB for seven hours straight is normal

. But, I think we all enjoy days like that from time-to-time
Now that you have the DC Mods, can you hear any difference? Using the MB-100s for bass it should be tighter, better defined, with slightly more detail, all-in-all a bit more immediate and real sounding.
So, don't worry in the future, not only do the MB-100s sound great but they are easy and inexpensive to fix. IRD will support them (original and used owners) well into the future.
So, what's next? How about cleaning the attic

Enjoy.
