Peg, I believe that the consensus of the previous replies is correct. Although that site is generally a very reliable source of information, that particular point seems questionable at best. The outputs aren't "combined" and 240 watts don't result. Each half of the speaker is driven by a separate 120 watt amp section and can't "borrow" from the other amp in the unlikely situation that more was needed. As Alan points out, there's still just one power supply section in the 3805 to supply all of its amp channels. It would appear that at most there would be a reduction in the total load carried by the output transistors in two amp sections, but this wouldn't create any audible benefit and it would be uncertain if the service life of the sections involved would be significantly lengthened. In my view not worth the bother; in most setups the 3805 should be fine with the M80s as is.
