IHF power, usually IHF peak power is power output from a 20 millisecond tone burst. There are 1000 milliseconds per second. IHF peak power is usually used by lower quality gear to give a higher output rating. Most amplifiers can produce more instantaneous peak power for a very short time. I would be concerned about an amplifier's RMS power output.

The IHF Standard on Methods of Measurement for Audio Amplifiers (IHF-A-201) of 1966 is in itself a revision of the earlier IHF standard of 1959. In particular, this new IHF standard recognizes that amplifiers can have more than one channel of amplification (i.e., a two-channel stereo amplifier) and that these 290 channels can interact with each ...

IHF-A-Network vs New IHF S/N specs. mgallant over 8 years ago. Below are some S/N specs. from a ~ 1986 Yamaha AX-900U power amplifier. What is the difference in measurement setup for the "IHF-A " versus the "New IHF"? I'm only interested in the "CD etc" results. It looks like the "signal level" is not mentioned for the CD results.

For analogue audio output, the D/A circuit is one of the most important circuit blocks since it recreates the original analogue waveform from a digital source, such as a CD. For the D/A converters, Asahi Kasei Micro devices’ top-of-the-line DAC AK4497, with their high S/N ratio and low distortion, are isolated for the left and right channels.

Googling “IHF A-Network” didn’t get anything meaningful. However, I found at the Rane Professional Audio Reference that the “IHF (Institute of High Fidelity) is the old organization of North American hi-fi manufacturers that created voluntary industry standards for testing and specifying consumer electronics. The IHF merged with the EIA ...
How to write (and read) audio specifications
http://www.sengpielaudio.com/Mathew-AudioPrecisionSpecifications.pdf
audio analyzers, this is a key speci fication, one we would like to tout. We claim ≤ –112 dB residual THD+N in a 22 kHz bandwidth. You can see that for most amplitudes above 400 mV the THD+N is well below this. If you are working at a 2 V amplitude, it is …
Audio system measurements - Wikipedia
https://en.wikipedia.org/wiki/Audio_system_measurements
Audio system measurements are a means of quantifying system performance. These measurements are made for several purposes. Designers take measurements so that they can specify the performance of a piece of equipment. Maintenance engineers make them to ensure equipment is still working to specification, or to ensure that the cumulative defects of an audio …
