I performed a full set of measurements on Schiit Audio's Ragnarok 2 using my Audio Precision SYS2722 system (see the January 2008 "As We See It"). I preconditioned the amplifier by running it at one-third the specified power into 8 ohms for 45 minutes. At the end of this period, the temperature of the top panel had stabilized at 106.0°F (41.1°C), while the heatsinks measured 126.9°F (52.8°C). This amplifier should be placed in a well-ventilated location.
Looking first at the small-signal measurements with line-level input signals, the Schiit amplifier's…
