According to the affable grandpa of high-end audio, Paul McGowan, PS Audio will start publishing measurements made with an Audio Precision analyzer before the end of this year.

Paul McGowan throws in the towel (Not really but it’s movement in the right direction)

It’s a win for the consumer and at least they are upfront about the reasons for doing this.
Well, this place does have some influence after all...
Not bad for "a bunch of data nerds on a forum". (random quotes from random audiofools).

I think I heard that before from someone else
I guarantee you did.

Absolutely... accusations there of incorrect measurements, "happens all the time". I'd like to see Paul prove that... no point making comments like this without hard data to back them up. Now blaming ASR for reduced sales... you must be joking Paul.
I watch further... he says some people should have their AP's taken off them, then makes this face;
Then suggests they have taken 50 years, but now will get around to publishing measurements... better late then never I suppose.
ASR has pulled PS Audio into measurement submission... will be interesting to see if these measurements compare to others.

He's hardly "throwing in the towel". PS Audio has had AP test stations for decades longer than most.
And whoever did overdrive one of their integrated amplifiers with 4V if the specifications clearly stated a much lower sensitivity for full rated power, did absolutely make a knuckleheaded move. But that wasn't Amir I don't think.

To me, as an an electronics layman, his arguments against publishing the raw data make sense to a certain extent. Since yes, there is probably no way one can hear the difference between 0.0001% and 0.00000001% distortion. Or what have you. However, these measurements don't say much, if anything, about other important characteristics of an electronic device. Like safety, durability and usuability. And still, publishing these measurements will convince some people to buy a device solely based on this. Cause "this is clearly better".
Anyway, like often, the truth lies somewhere in the middle.

If I recall correctly, he didn't measure any integrated amp from them apart from the Sprout (by the way, worst audio product's name ever)
Two power amps, tho :
Review and Measurements of PS Audio S300 PWR Amp
This is a review and detailed measurements of the PS Audio Stellar S300 Stereo Power Amplifier. It is on kind loan from a member. The S300 costs US $1,499 from the company. Fitting the design language of the rest of the PS Audio and using similar enclosure, the S300 is quite hefty considering...

PS Audio M700 Monoblock Amplifier Review
This is a review and detailed measurements of the PS Audio Stellar M700 Power Amplifier. It is kindly sent in by a member and costs US $2998 for a pair from the company direct. The M700 is quite heavy for a class-D amplifier. I picked it up by hand and nearly hurt my back trying to hold it...

Let's hope that once they start measuring, they will see and address obvious sources of noise and distortion. I suspect that is part of the plan and hence the reason they are giving themselves 6 months to do this. But too hard to admit it now.
As to differences in distortion specs, they already provide that number so that comment is non sequitur.

Let's hope they would take the same way Schiit did...

I hope this goes better than it did with Max Townshend. After more than a year of waiting for proof, the unfortunate end result was still a big fat nothing.
Really though, Paul should have been providing measurements long ago. One of his “power conditioners” was found to do less than a Noma power bar.

Should be fascinating to hear their explanation for their products poor measured performance.

That's a good move from their side.
It can be only beneficial in a long term.

Not sure about good... necessary for sure.
We'll see... when people can compare their products to others, see the measurements are similar but the price isn't. Well, that may well not work to their advantage at all.

It will, people who buy their products already doesn't care much abut measurements.Not sure about good... necessary for sure.

People who care won't feel cheated as they will know how it measures, so it will be conscious decision to buy or not to buy.
And in the future they might actually care more about objective data (and "fixing" some of the "problems"), which will cover folks from both objective and fully subjective side.
Hope that helps.
