Can anyone tell me what amplifiers go well with the B&W 703s/705s?

Ideally an amplifier should be a constant voltage source.That is ,for a given input signal,the amplifier should produce a constant voltage across the speaker terminals whatever the load.Each time the load resistance is halved,the amplifier should double its output.To make this happen,the amplifier's power supply must also double its current delivery to the output transistors.The continued doubling must stop at some point and ,if carried too far,could end in disaster.Either the power supply will run out of current and fail to maitain the amplifiers output wattage, or worse , go beyond the capability of the output devices,creating excessive heat and eventually destruction of the transistors. The best amplifiers are unconditionally stable with any load and any signal.

So to summmarize ,the amplifier needed to match your B&W speakers should :

(1) Have enough clean (continuous,rms) watts to drive the speakers without distortion.

(2)Be able to deal with impedance variations supplying the necessary current to the speakers without audible distortion

(3)And to be unconditionally stable with any load and any signal.

.It is not important what brand you choose as long as the amplifier meets these requirements.
