Muralman1, your Acoustic Reality amp is solid state! Solid state essentially means that the circuits utilize transistors rather than vacuum tubes. Truly digital amplifiers, not those with just a digitally regulated power supply, amplify the audio signal in the digital domain. They generally have complex semiconductor chips (containing lots of tiny transistors) that save space and are more energy efficient in comparison to using a circuit board with discrete electronic components amplfying in the analog domain.
To this point, I believe that the major benefits of digital amplifiers are for the manufacturers, not the audiophile. Digital amps make sense for computers and products that must be physically small. When used with more traditional audio components with analog outputs, their use requires unnecessary steps of digital to analog and analog to digital conversion.
