Very interesting to see what a thread this has become.

I have another question, back to the HK AVR520. What about testing the M80Ti's with the bridging bars removed and seeing if the 520 still goes into protection mode?

In the mean time, I have set up the M80Ti's in the receiver as "small" speakers, and have handed over the bass handling solely to the EP350 subwoofer. So far, this seems to be working OK. Still, I definitely want to resolve this and I guess if that means buying an amp, so be it.

Thanks,

Doug
