"Excellent sound mating with Gallo 3.1."
This is probably because Anthony Gallo develop his speakers AND , as a rule, display his speakers (CES 2009, I am not sure about RMAF 2009) with class D amplifier - Musician III by Spectorn Audio.
As a matter of fact many other speaker designers like late John Danlavy, Albert von Schweikert use Spectron amplifiers as well in their speaker developments
All The Best
