So it was with the Micromega AS-400 digital source/integrated amplifier ($4495), the anonymity of which was compounded, in my case, by a generous helping of forgetfulness: I suppose I was told, ahead of time, that this was a class-D amplifier, but at some point in time before my first at-home audition I apparently…

To perform the measurements on the Micromega AS-400, I mostly used Stereophile's loan sample of the top-of-the-line Audio Precision SYS2722 system (see the January 2008 "As We See It" and www.ap.com); for some tests, I also used my vintage Audio Precision System One Dual Domain and the Miller Audio Research Jitter Analyzer. Before I did any testing of the Micromega AS-400 I ran it at one-third power into 8 ohms for an hour, which imposes the maximum heat stress on an amplifier with a class-AB output stage. As the AS-400 is a class-D design, one of the benefits of…

Many, though certainly not all, musicians of most genres dream of composing, crafting, birthing a hit record—one they will forever be known for, and that will make them enough money that they'll never have to sleep on another hard floor or friend's stained couch as long as they live. Very few fulfill this dream, and those who do often don't know why or just how it happened…
We went to a record store near Dupont Circle quite often. I don't know how my mother found out about new recordings, but she always seemed to be picking up something to listen to. I had a record player in my room and listened to…
