No need for Amir's AP to test this. Just use digital loopback to feed into REW or Multitone or other measurement software and use your favorite player with this VST enabled to see the result. Here are some examples:Amir. Can't you try this for fun? This eternal rant about the cozy tube distortion sound you know. At least that way we know if the program delivers the distortion it claims. After that, people can test for themselves and see how cozy it is (in the long run) with a lot of distortion.![]()
What is PKHarmonic?
PKHarmonic is a VST plugin for Windows, designed to add second and all the way up to the 8th harmonic by simulating a device non-linearity. A simple slider control for each harmonic lets you fine tune the level from -200dB to +10dB in real time, as you listen. This makes it possible to configure your playback software to generate similar levels of distortions to simulate a tube preamp or an amp, or another device with some level of non-linearity.

PKHarmonic VST Plugin - Audiophile Harmonics Generator | Distort documentation
PKHarmonic 1.0 is the initial release of this software. Use at your own risk!distortaudio.org
It is perfectly sufficient for me with the tests you performed.No need for Amir's AP to test this. Just use digital loopback to feed into REW or Multitone or other measurement software and use your favorite player with this VST enabled to see the result. Here are some examples:
H2 set to -60dB at 0dBFS 1Khz, using Foobar2k to play:

REW measurement of a 0dBFS 1Khz sine shows H2 at -60dB:
View attachment 428515
Same PKHarmonic setting, but now playing a two-tone DIN250/8k test signal at -1dBFS:
View attachment 428516
Let's add a higher level harmonic, H3 at -99.8dB:
View attachment 428521
Let's see if this does the right thing by measuring in REW. H2=-60dB, H3=-99.8dB, as expected:

And add higher-level harmonics:

Result: all harmonics measure exactly as set in PKHarmonic:

And with DIN250/8k signal:

Any other tests that you'd like to see?

Yes, one and the sameAre you the one who created the PKHarmonic VST Plugin? Well done I must say.![]()
Actually, I don't think we have seen measurements for a Purifi 1ET6525SA based amp yet. I'd be keen to see these, especially the power sweeps at different frequencies (as these are not on the datasheet).We need another chinese DAC review or Purify/Hypex power amp review like we need a hole in our head.
I'd like to see more AVRs etc being measured too.Home theater devices are more problematic, very common, and not as often reviewed. I think this is where some efforts would pay dividends.
Its going to be in the upper end of the scale with the only blemish being mediocre distortion above 7khz and 10w.Actually, I don't think we have seen measurements for a Purifi 1ET6525SA based amp yet.

I have two AVRs here waiting to be tested.I'd like to see more AVRs etc being measured too.
No, it is not you. It broke when we upgraded our underlying server APIs. Developer is working on fixing it....Speaking of which, I used to be able to go to the "Reviews" tab and select whatever product I wanted to see; I don't see that selection anymore. Is it somewhere else now or am I totally missing it?
