There are a bunch b&w have always liked krell the bottem end deserves it but you would have to get a tube pre to sweeten the mids also perhaps a threshold one of my favorites was the sa 3.9 60 pure class a now there is sweetness and punch another is the classe dr 9 but once again you need tubes or a matching pre to really enjoy it ... you can pick up the krell ksa 150 ...$ 1700-1900 the threshold sa 3.9 ...$ 1500 and the classe dr9....1300-1600 think krell the 801 need the control in the bottom end also if you have stands fill them with sand that helped when i had them good luck enjoy
