I know that EITHER one of the amps by itself will be perfectly fine with the 4-ohm load. NADs are capable of delivering huge amounts of current. Its the nature on bridging that creates the problem.

I'll start out by un-bridging the amps, using the 370 as pre-amp only, and drive the M80s with the 270 only. 'Only' in this case a 120w/ch, so I should be OK.

If anyone has any experience with bridging, I'd be interested to hear it. Alan has chimed in and recommended following NADs advice, and not to bridge due to the 4-ohm load.

In any case I'm eager to get the speakers and have a go. I ordered them on Thursday and got the shipping email on Friday, and am waiting for them to show up on the DHL tracking site! I assume Axiom uses a freight forwarder in Canada to get them to the USA, where DHL takes over. That would explain the two day delay in the tracking numbers showing up. When I get other international shipments from DHL, I can track them all the way in.
