Id say look into Class D as well
. Wyred, or Bel Canto maybe. With the right SS preamp, maybe the NuForce amps.
Ive heard a few Legacy units. Focus, IIIs, Studio. Each one had diff amps. The better the amp in terms of quality, as much as power, were the better sounding units. Rotel, Yamaha, and Harmon Kardon.
They are eff speakers but have a low imp range
newer ones, with their own sub/bass amps, are easier loads.
Id want 200 300 wpc minimum
myself.
Maybe a Rowland Capri preamp, and some D amps, Audience, Voodoo, SR, Kimber, Harmonic Tech or Audio Art wires and you should be hot to go.
For a tube pre, the VTL 2.0 sells here often enough, so does Horizon and Monarchy
for pre solutions in the not too pricey but pretty good camp.
Class D power is probably going to be your best value in the cost per watt arena these days
and the non Hybrid Legacys like power.
