Merrill Audio Veritas Monoblock Amplifiers: Are All Class-D Amplifiers the Same?


Have Class-D amplifiers gotten a bad rap? Despite my colleague Guido Corona's enthusiastic review of Merrill Audio's Veritas amplifiers (HERE) some four years ago, the sound and performance of all Class-D amplifiers still tends to be lumped together and in the words of the immortal Rodney Dangerfield, "…don't get any respect."

Benchmark AHB2 Amplifier


I've had my fair chance at messing with all sorts of amplifier technologies, from Class A, to AB, D, even T—you name it, and each one carries their own sonic signature.
