Does anyone know if they can properly drive them UNbridged, where one drives left and right Tweeters and other drives left and right midrange/bass.

Maybe you can get that fixed. Did new ones do that?

Later DR series amps have soft-start and speaker relays to fix this. A repair guy told me that sometimes this pulse is caused by failing supply caps. Be advised that this pulse is MUCH larger when the amps are bridged for monobloc use. I smoked a pair of boombox speakers when connected this way. The boombox speaks handled a single amp just fine. Dispite the low power but high quality of the sound these things produce DON'T run them directly connected to a tweeter in a bi-amp or tri-amp setup with out some sort of low and midrange blocking arrangement. Great sounding amps though!! I love mine.
