Rooze...The bridged zr1600 is good for 1600 watts into 4 ohms, and biwire makes no difference.
However, neither the Carver or the Krell is delivering anything like this power. If it did, I don't know if your ears or your speakers would blow out first! There are characteristics of an amp that just naturally go along with high power capability, and these characteristics, rather than the high power per se, are what makes a high powered amp sound better.
I tend to believe that the 600 watt capability of the Carver is enough of a good thing for your Maggies, and that bridging them is overkill. I am not surprised that you found the single stereo amp configuration equal to the bridged one. The only rational use for the second Carver would be biamping, using an electronic crossover.
I think that the "giant killer" description refers to a modified Carver. There is a lot of low level signal processing that is useful for the pro sound application but unnecessary for home audio. This circuitry is easily bypassed.
However, even in stock form I think that it's a damn good amp, and using it instead of one of those "giants" makes it possible for those with limited funds to spend several grand more on speakers. Such a speaker upgrade more than equals any subtle improvement through other amps.
