Re: Sunfire TGA-7401 vs. Parasound Halo A51 vs. Wyred 4 Sound MC5x500
As for the Sunfire/Bob Carver Designs, he has been using what he calls a Tracking Downconverter. It is a Switching Power Supply Design that predates designs like the Bang & Olefsen ICEPower, Behringer, et al.
Where a great deal of the electricity a Class AB or Class A draws becomes heat, Amplifiers like the Sunfire are claimed to be 95% efficient. As with all things, there are those who find that Class D Amplifiers are best used for applications like Subwoofers, but that perception really seems to be changing.
