I’m talking about the Audio Precision’s auxiliary AUX-Filter which goes between the Class-D and the AP Analyser, it’s a 52db per octave passive low-pass filter and can only take low power, it eliminates the Class-D’s switching noise for testing purposes only can’t be used for real music levels, even Stereophile state they can only put low power wave forms through it with it in use.

I said it years ago if you have a look in their comments, when Stereophile first started using this AP AUX switching noise filter, I complained they weren’t showing us anymore what is representative of what comes out of the speaker terminal of Class-D with this AP filter in between the Class-D’s output and the AP Distortion Analyser, especially the screen shots of the 10khz square waves.
As you can see years back Stereophile used to show with (top) and without the AP low pass filter, and it’s always used at very low power.
Today they never show the square wave "without" the filter in line (bottom), which is not representative what’s coming out of the speaker terminals.

I am going to guess I have far more experience with AP equipment and getting the most out of it than the average Stereophile writer who is a casual user. Hint that filter is optional dependent on external circuitry and amplifier performance.

Yes your the best, and yes your a"Dreamer".

JA (John Atkinson) would have so many more hours than you on AP test gear it’s not funny. That all he does all day every day, is measure everything Stereophile reviews and subcontracts out as well.

Stop "trying" to big note your self, and go back to saying how good OTL amps are for driving bad speaker loads like the Alexia’s, that only made you look half as bad, we can’t follow two ridiculous claims at once.
