I have B&W 802's seires two with the protection cuircitry
removed.I have driven them with the Arigon 4004 Mk2, Chord 860, and most resently Bel Canto Evo 200.2 as mono blocks. By no small margin has the Evo's 200.2 out preformed the others.I might also add to the list of amp's used the Briston 4B ST. Extremly fast, liquid, airy detail without any harshness. Some find vocals a little resessed as I also did until I added good quallity silver interconects.
