Amplifier distortion

0dBV into Amon corresponds to 90dB, but only 76dB into Hathor. Hence why I measured at higher Voltages for Hathor - to put things into context.

The Ragnarok has a very interesting bias scheme, which is why it is especially hard to measure. The distortion I get with the sweep appears to be higher than it would be with a tone burst, at least according to the stereophile measurements.

15dBV corresponds to 10W into Hathor.

The Ragnarok is a very interesting amplifier, with its microprocessor control allowing it to pass and amplify DC signals, while continually adjusting bias so that the quiescent DC bias is set so the output DC is zero. This works surprisingly well.
