It would be helpful if you could spell out what you mean by "220W D Biamped". I think you mean either two 220 Watt per channel Stereo amplifiers or possible one amplifier Biwired. Are you really suggesting 3 stereo 140 Watt per channel class AB amplifers saying "triamped"??? Anything is possible.
I do agree that using multiple amplifiers on one speaker -of reasonably high caliber- that more power will be delivered.
I also think that for a recommendation you should find the amplifier that you find most pleasing of suitable power and use that one or that one pair of monoblocks.
