MEASUREMENTS

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”¹). 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 maximum voltage gain, measured at the loudspeaker outputs, was 29dB into 8 ohms with the gain set to “25,” 18.6dB with it set to “8,” and 5.9dB with it set to “2.” (Schiit specifies gain in multiples—2×, 8×, 25×—instead of the usual dB units.) These gains were identical for balanced and single-ended input signals, and, on the 8× and 25× settings, match up well with the
