Musical Fidelity has the solution to your low power problem. If you have an older receiver or integrated amp with no preouts that has everything you need aside from loads of power, you can supercharge it! If your receiver or integrated can output at least 50 watts per channel this thing can supercharge it to 550 watts, and should be able to take any load you throw at it with all your new found power. The supercharger is a monoblock amplifier with high and low level inputs for full flexibility, or at least as flexible as monoblocks get. Musical Fidelity Supercharger
