1) try to find out the QUAD distributor and ask them;
2) the Quad will provide much greater transparency and tonal accuracy than the Mags. This does not mean you will like the Quad better but it is a far superior speaker in virtually every musically important area.
3) I believe the efficiency of the new Quads is around 87 dB and any good 50 wpc amp should be enough. With the Quad it is more a question of the quality of the amp than the amount of power available. I have always preferred them with tubes but I know several who have used good ss with considerable success.
