Agree. The Gilmore Raptors have substantial linear supplies.
This is one feature that allows them to produce very little RF noise of their own. When I added them to my system, I was able to track down and ameliorate external RF noise sources in my house. It turns out that every major appliance these days has a computer and a switching power supply inside, and most of these run continuously even if the appliance is idle.
For example, our dishwasher and clothes dryer are significant RF noise sources just sitting there. Appliances such as microwave ovens and digital video recorders are obvious, but it is amazing how much the audio system improves by just switching off the power to the dryer at the breaker panel.
