Gilmore Audio Raptors are wonderful!

These are 500 watt per channel monoblocks that stay cool no matter how much power your Maggies demand. Mine are MG-20s.

In order to audition them, I had to rewire my crossovers to go back to full-range operation (I formerly used hybrid biamp with separate amps and cables for bass and mid/treble). The rewire is now a tri-wire setup with the tweeter crossover and cables completely separate after the spade connectors.

Even with the stock Magnepan outboard 132 microfarad midrange high-pass caps and bass low-pass (with augmented R-C filter on the bass panels and replacement mid/treble crossovers), the sound is better than anything I had before. I thought I had good bass-midrange integration before, but the control offered by these amps tames several speaker resonances and gives a bass and midrange delineation that is hard to believe. Their output impedance is far lower than the InnerSound amp, and they use no feedback to be confused by stored energy in the speakers.

I was concerned that the class-D operation would cause treble veiling, but these amps are the cleanest and quietest I've heard in my own or any other system. They use a chip set made by a well-known manufacturer, but have linear power supplies to avoid the noise issue with switching supplies.

It is too soon to say anything definite about the noise rejection, but they seem to be more immune to the RF noise in my environment than my previous setup (OTL monoblocks for mid/treble and InnerSound ESL-300 for bass).

Very highly recommended!
