Sorry not what you want to hear but yes the LRS sound great but need lots of power. I have bi-amped Audiosource Amp Three amps putting out 200 watts into 4 ohms and they still get hot. I have thermoregulated fan units for them. I blew up an old cheap 80 watt Yamaha amp trying to drive an old pair of MMGs and the LRS are even less efficient. The Amp Threes can be found cheap used and I think they sound fine.
They need time to break in and power to make them sing, but they sing. Being able to easily move them around is cool also.
