Optimizing McIntosh 7300s as monoblocks


I have been lucky enough to find 2 MC7300s to drive a pair of Cello Strad Premieres in a BIG room. Can anyone tell me the best way to connect the tri-wire Cello Strings to the amp taps? They are bridged and using just the 4 ohm taps, as recommended, isn't cutting it. Is it risky to use the 2 ohm taps (remember: bridged, thats 2+2=4, and 4 is the minimal impedance of the Cellos). 6 is nominal. So should I use the 2 ohm taps for bass and the 4 ohm taps for mid and high?

Thanks one mil...

Went with the 2 ohm taps and found a lot more room. So I'll probably go ahead and just experiment with using the 2 ohms for bass and the 4 ohms for high & mid, one reason being I'd like to connect (triwire) all three pairs of speaker terminals to the amp with the Cello Strings (the Mac binding posts barely let me squeeze 2 spades onto a tap). But...

Should the bass get the lower impedance or should the high & mids? While the bass demands the most, lower impedance doesn't equal power so much as headroom, right? At 4 ohms, the bass seems looser while the highs and mids are walking around like they own the place. This may all be due to new interconnect config, so......
